Past and Present Award Winners
NOMINATION PROCEDURE - The 2009 ASPB award nominations will open January 2, 2009. The deadline for submissions is February 27, 2009.
Adolph E. Gude, Jr., Award
This monetary award honors the Gude Family, who made possible the establishment
of the Gude Plant Science Center. The award, established by the Society and
first given in 1983, is made triennially to a scientist or lay person in recognition
of outstanding service to the science of plant biology.
Adolph E. Gude, Jr. Award Committee
The 2007 winner is...
Winslow
R. Briggs
Carnegie Institution of Washington
Winslow Briggs will receive the 2007 Gude Award for his outstanding service
to the plant science community. Winslow was a member of the editorial board
of Annual Review of Plant Physiology and Plant Molecular Biology
for 33 years, including 21 years as editor; served as president of the American
Society of Plant Physiologists, the California Botanical Society, and the American
Institute of Biological Sciences; organized several Gordon conferences and international
meetings; and, for 20 years, was director of the Plant Biology Department of
the Carnegie Institution of Washington.
Many students have been mentored and many visitors hosted in Winslows
laboratory. His contributions have helped shape the fields of plant physiology
in general, and of photomorphogenesis in particular. Our present understanding
of blue light photoreception comes in large measure from his 40-year personal
quest. Winslow has shown by example how great science and great humanity can
go together, how great science is always a team effort, and how joyful it can
be. For his many contributions and years of service, it is most fitting that
Winslow Briggs should receive the Gude Award.
Charles Albert Shull Award
Created in 1971 to honor the Societys founding father and the first editor-in-chief
of Plant Physiology, this award is designed to recognize young researchers.
It is a monetary award made annually and is given for outstanding investigations
in the field of plant biology by a scientist who is under 45 years of age on
January 1 of the year of presentation, or who is fewer than 10 years from the
granting of the doctoral degree. The recipient is invited to address the Society
at the annual meeting the following year.

Sheng
Luan
University of California, Berkeley
Sheng Luan is this year’s recipient of the Charles A. Shull Award for outstanding
investigations in the field of plant biology by a scientist who is under 45 years of
age. Sheng received his BS degree in biology from Laiyang Agricultural College in
1982, his MS degree in 1985 from the Shanghai Institute of Plant Physiology, and
his PhD degree in 1991 from Harvard University under the direction of the late
Professor Bogorad. He then continued at Harvard with Professor Schreiber for
postdoctoral research, where he identified immunophilins as abundant chloroplast
proteins and also identified a novel calcineurin-like signaling system in plants.
Sheng then joined the faculty at the University of California at Berkeley and
attained the rank of professor within 10 years. Major discoveries made by Sheng
and his colleagues have opened up new horizons and have stimulated new areas of
research, thereby enlightening the future.
Pioneering contributions have been made by Sheng and his colleagues in four
major and distinct areas of plant biology. In calcium signaling, a major question is
how plant cells interpret calcium changes specific to a particular signal. Sheng’s
work over the past 10 years has established a complex molecular network that
decodes calcium signals involving calcineurin B-like proteins (CBLs) that, unlike
their animal counterparts, regulate a large family of protein kinases known as
CIPKs (CBL-interacting protein kinases). In response to low K-nutrition, myristoylated
CBLs target CIPKs to the plasma membrane, where they activate an inward
voltage-gated potassium channel (AKT1) responsible for high-affinity potassium
uptake. The channel is then inactivated by a specific PP2C-type protein phosphatase
to reset the signaling cycle. Thus, Sheng has elucidated a complete signaling
pathway responsible for plant response to nutrient stress. Another major
contribution to the field of membrane transport involved identification of Mg
transporters, MATE-like transporters for alkaloids, and an HKT-type transporter
critical for salt tolerance. Of particular significance is the HKT-type sodium transporter
that was recently shown to be responsible for salt tolerance in rice. In collaboration
with rice breeders in China, Sheng found that expression of this gene
in elite rice varieties increases salt tolerance. As a result of this pioneering work,
it will be possible to grow rice in saline soils, thereby reclaiming unused land to
cultivate crops. Following the trail of signal transduction, Sheng was the first to
demonstrate the role of tyrosine dephosphorylation in plant cell regulation by
identification of a bona fide tyrosine phosphatase. The tyrosine phosphatases play
a key role in regulation of MAPKs and surprisingly in regulation of starch metabolism
in plastids. Sheng and colleagues demonstrated that a specific tyrosine phosphatase
(DSP4) binds to starch granules in a light- and redox-dependent manner,
thereby establishing a new mechanism by which starch metabolism is regulated
on a daily basis. The fourth area is also plastid based, and involves the
immunophilins that are localized in the thylakoid lumen. Sheng demonstrated that
these enzymes are regulated in an unusual way; they are activated by oxidation,
consistent with their operation in an oxidizing environment. They function as
chaperones involved in the assembly and maintenance of photosynthetic complexes.
Thus, these studies have relevance to photosynthesis and bioenergy, and may also have commercial application for production of medically important proteins
in transgenic plants.
In addition to research, Sheng is active in teaching and service to the scientific
community involving editorial assignments. He has served on the editorial board
of Plant Physiology and is currently an associate editor of Plant Signaling and
Behavior and founding editor-in-chief of Molecular Plant. For his collective contributions,
he richly deserves to be honored with the Charles Albert Shull Award.
Charles F. Kettering Award
This award was established by an endowment from the Kettering Foundation in
1962 to recognize excellence in the field of photosynthesis. It is a monetary
award to be given in even-numbered years to an individual for meritorious work
in photosynthesis.
Charles F. Kettering Award Committee
The 2008 winner is...
Robert
E. Blankenship
Washington University
The Charles F. Kettering Award of the American Society of Plant Biologists for
2008 is awarded to Robert Blankenship. This award, established by the Kettering
Foundation in 1962, is intended to recognize excellence in the field of photosynthesis.
In Bob’s 30-year career, he has set very high standards in research, teaching,
and service.
Bob’s impact on the field of photosynthesis has been broad and multidisciplinary,
encompassing photosynthetic bacteria, algae, and terrestrial plants. His many
publications in highly regarded journals are testimony to his seminal and varied
contributions in areas as wide-ranging as primary electron transfer events, antennae
structure and function, the origin and evolution of photosynthesis, and even in astrobiology. In his extraordinarily diverse research, he has studied photosystems
using fast spectroscopy and many other biophysical approaches. Bob’s research
has been key to our understanding of the antenna systems and reaction centers of
plant photosystems I and II, cyanobacteria, and the purple and green bacteria, and
he has pioneered investigations of unusual photosynthetic organisms such as the
heliobacteria and a newly discovered green sulfur photosynthetic bacterium living
near deep-sea hydrothermal vents that utilizes light from geothermal radiation.
Bob’s interest in the evolution of photosynthesis was kindled during his early
experience in teaching as assistant professor at Amherst College. Since then, he
has developed a world-class research program producing far-reaching insights
through use of molecular and genomic approaches to explore the evolutionary
pathway between anoxygenic and oxygenic photosynthesis. The structure-based
sequence comparisons of reaction center complexes performed by Bob and his colleagues,
across most groups of phototrophs, resulted in a widely accepted proposal
of a unified evolutionary tree in which horizontal gene transfer has been a central
feature.
While chairman of the Department of Chemistry and Biochemistry at Arizona
State University, Bob was instrumental in attracting federal funding to establish the
Center for the Study of Early Events in Photosynthesis. Under his leadership over
10 years, the center gained widespread recognition as the leading group of investigators
in photosynthesis, all of whom Bob recruited.
Bob has provided unparalleled service to the field of photosynthesis, of which
three contributions stand out as particularly significant. He was editor-in-chief of
Photosynthesis Research for 11 years, and his hard work was important to the success
the journal enjoys today. Subsequently, he served as president of the
International Society of Photosynthesis Research, 2001–2004. Finally, his 2002
textbook, Molecular Mechanisms of Photosynthesis, was a tremendous undertaking
to cover the molecular basis of the life-essential processes of photosynthesis; it
is recognized as a standard primer in the field. Bob has obviously been interested
in the big picture of how photosynthesis evolved, its diversity among organisms,
and the variations of mechanisms that organisms use to harvest and utilize solar
energy. His exceptional personal and organizational skills, enthusiasm, and interest
in education have also made him a very effective advocate for general scientific and
photosynthetic research. His achievements exemplify the qualities recognized by
the Charles F. Kettering Award, and the Society is pleased to present this year’s
award to Bob Blankenship.
Charles Reid Barnes Life Membership Award
This is the oldest award, established in l925 at the first annual meeting
of the Society through the generosity of Dr. Charles A. Shull. It honors Dr.
Charles Reid Barnes, the first professor of plant physiology at the University
of Chicago. It is an annual award for meritorious work in plant biology; it
provides a life membership in the Society to an individual who is at least sixty
years old. Membership is not a requirement for the award, and, if appropriate,
every fifth award should be made to an outstanding plant biologist from outside
the United States.
Charles Reid Barnes Life Membership Award Committee
The 2008 winner is...
Tsuneyoshi
Kuroiwa
Rikkyo (St. Paul's) University, Tokyo, Japan
Tsuneyoshi Kuroiwa is the recipient of the 2008 Charles Reid Barnes Life Membership
Award. Tsuneyoshi received his SciD from the University of Tokyo in 1971 and
subsequently held a faculty position there until his mandatory retirement in
2003. He currently holds a position at Rikkyo (St. Paul’s) University
in Tokyo.
Tsuneyoshi is a pioneer in the cytological analysis of chloroplast and mitochondrial
dynamics in plants and algae. By combining a variety of sophisticated imaging
technologies with the creative use of model systems, he has made outstanding
contributions in two important areas of plant cell biology: 1) Mechanisms of
organelle division. Tsuneyoshi detailed studies of the plastid and mitochondrial
division rings that have been instrumental in establishing the assembly and
disassembly dynamics of the division machineries in these organelles and laying
a foundation for understanding the functional roles of organelle division components
at the molecular level. 2) Mechanisms of maternal inheritance of organellar
genomes. Tsuneyoshi discovered that inheritance of organellar DNA in algae,
plants, and animals involves active digestion of the paternal DNA. In the context
of this work, to better visualize organellar DNA, he developed an improved fluorescence
microscope, later marketed by Olympus.
Tsuneyoshi also spearheaded the recent sequencing of the genome of the primitive
unicellular red alga Cyanidioschyzon merolae, which he has systematically
developed as an evolutionarily important and experimentally tractable model system
for analysis of organelle division and other aspects of organelle biology in photosynthetic
eukaryotes. In all, he has published over 360 papers throughout his
career and continues to publish groundbreaking research on organelle biology and
evolution in the top-ranked scientific journals.
Tsuneyoshi has been an influential member of the Japanese scientific community.
He has trained and promoted the success of many young scientists and served the
plant biology community generously in a variety of editorial and other professional
capacities. He is past president of the Botanical Society of Japan and the Japanese
Society of Plant Morphologists and is a member of the Science Council of Japan.

The 2008 winners are...
Chu-Yung Lin
National Taiwan University
Chu-Yung (CY) Lin has successfully motivated several generations of prominent scientists
to study plant biology, many of whom are currently training the future generation(s) of plant biologists in the United States and abroad. A few notable examples
of former students and current ASPB members include Renee Sung, David Ho,
Heven Sze, and Tony Huang. After a stellar academic career that spans five
decades, CY is currently professor emeritus at the Botany Institute, National Taiwan
University (NTU). He has also been an active ASPB member since the 1960s and
continues to regularly attend the annual Society meetings.
CY's undergraduate education was in Taiwan, and he obtained a PhD degree from
the University of Oklahoma in 1963. His thesis was on plant hormones, a Awards
Citations topic that he continued to study as a postdoctoral fellow with Joe
Key at Purdue University. This collaboration continued after Joe moved to the
University of Georgia, and a number of classic papers emanated from this long-term
association. CY returned to Taiwan and NTU in 1966 and quickly rose through
the ranks to become professor of plant biology in 1975. During his tenure at
NTU he served as chair of the Institute of Plant Biology and dean of the College
of Science. His substantial research achievements have been duly noted by the
Taiwanese funding agency, the National Science Council, with the award of six
Research Distinguished Awards and three Distinguished Awards. In 1998 CY was
elected academician in the Academia Sinica, Taiwan.
The distinguished scientific achievements of Chu-Yung Lin mainly center on the
response of plants to abiotic stress, namely anaerobiosis and heat stress. He was
the first to show that under anaerobic conditions, polyribosomes rapidly dissociated
and a subpopulation of polyribosomes reassembled to direct the synthesis of
new proteins including ADH. Following return to aerobic conditions, the full complement
of polyribosomes was regenerated and the synthesis of normal proteins
restored, in the absence of new mRNA synthesis. This exceptional body of work
was published in numerous publications in top-tier journals like PNAS, Journal of
Molecular Biology, and Plant Physiology. CY has also been a pioneer in understanding
the function of small heat shock proteins (HSP) during plant stress
responses. Notably, he showed the accumulation of HSP correlated with the acquisition
of thermotolerance. And, similar to the anaerobic response, loss of polyribosomes
following heat stress was restored upon return to normal growth temperatures.
CY was the first to suggest involvement of the small HSPs in thermotolerance
by protecting cellular proteins from thermal inactivation. Again, this seminal work
was published in several publications appearing in PNAS.
Federico Sánchez
Instituto de Biotecnologia, UNAM, Mexico
Federico Sánchez is a full professor (Investigator Titular C) at the Institute of
Biotechnology (IBT), Universidad Nacional Autonóma de México (UNAM) at
Cuernavaca. UNAM is arguably the premier research university in Mexico, and
Federico is considered by many to be Mexico’s leading plant biologist. He was born
in Mexico City and received a BS in chemistry and an M.Sc. in biomedical research
from UNAM. His graduate work and PhD in the area of microbial genetics was
supervised by Francisco Bolivar and Raphael Palacios at UNAM. During the late
1970s, he came to the USA and the lab of Brian McCarthy at the University of
California, San Francisco. It was during this period that Federico developed an
interest in molecular and cellular studies of the cytoskeleton, through work on the
tubulin and actin gene families of Drosophila. He returned to Mexico and was
appointed investigator at the Institute of Nitrogen Fixation, UNAM-Cuernavaca,
and rose through the ranks to associate professor before switching departments to
the IBT. He also twice served as chair of the Department of Plant Molecular
Biology, UNAM, was the director of the Centro Internacional de Ciencas, A.C., and
is past president of the Sociedad Mexicana de Bioquímica.
Federico’s research focuses on nitrogen metabolism in nitrogen-fixing nodules of
legumes and on the role of the cytoskeleton during nodule formation. His early
work uncovered roles for the enzymes glutamine synthase and uricase using a combination
of molecular biology and biochemistry as nodulin genes in the common
bean, Phaseolus vulgaris. A decade after leaving UCSF, he rekindled his interest in
the cytoskeleton and developed a continuing collaboration with Peter Hepler to
study roles for actin and profilin during the signaling response of root cells to rhizobial
bacteria. This has led to an active exchange of many students between the
USA and Mexico, many of whom continue to bridge the fields of plant cell biology
and molecular biology/biochemistry while establishing their own independent
careers. The choice of common bean as a research organism is important for the
Mexican agricultural industry but has not been without limitations. However, a
major one—the ability to reliably transform this crop plant—was overcome in
2006 by a report from this group of a fascile transformation protocol. Research
from Federico and his collaborators is routinely published in the very best journals
in the field of plant biology, including Plant Physiology and The Plant Journal.
Federico Sánchez’s impact on the plant biology community extends well beyond
Mexico and the United States. He has been an editor and/or served on the editorial
board for numerous international journals, including Molecular Plant–Microbe
Interactions, Planta, and the Asia-Pacific Journal of Molecular Biology and
Biotechnology. He has organized major symposium sessions at past ASPB meetings,
with Carmen Quinto co-organized and hosted the 5th Mexico–USA
Symposium on Plant Molecular Biology (2003), and is chair of the XII International
Congress on Molecular Plant–Microbe Interactions. Importantly, he is actively participating
in the organization of the upcoming joint meeting of ASPB and the
Sociedad Mexicana de Bioquímica in Mérida, Mexico.
Alessandro Vitale
Instituto di Biologia e Biotecnologia Agraria, Italy
Alessandro (Sandro) Vitale is the leading plant cell biologist in Italy, but his impact
on plant biology is truly international. Sandro is currently research director at the
Institute of Agricultural Biochemistry and Biotechnology (IBBA) of the CNR in
Milano. He obtained a PhD from the University of Milano in biochemistry and has
been on the scientific staff of IBBA since 1982. He also conducted postdoctoral
research in the lab of Maarten Chrispeels at UCSD, where he worked on the
biosynthesis and intracellular transport/processing of bean phytohemagglutinin.
Sandro is an internationally recognized expert on protein trafficking and plant cell
biology. He has made significant contributions to our understanding of protein folding
and quality control in the endoplasmic reticulum, the site of protein import for the
endomembrane system. He has also pioneered work on the biosynthesis and targeting
of vacuolar proteins in plants, the ultimate destination for many storage proteins
and major site of protein degradation. These findings are routinely published in the
very best plant biology journals, including Plant Physiology and The Plant Cell.
Exploiting this knowledge of protein targeting, Sandro has recently extended his
research into biopharma. His group created an artificial storage protein, zeolin, which
shows great potential for adding an essential high methionine trait to protein of low
sulfur content crops. Emphasizing the promise of this research for third world countries,
the Gates Foundation cassava improvement project has chosen this topic to
increase the nutritional value of cassava and promote its use as a staple in Africa.
Sandro Vitale has provided valuable service to the ASPB community, including a
five-year stint as co-editor of The Plant Cell during which he set very high standards
of quality and fairness. Furthermore, Sandro continues to serve on the editorial or
advisory boards for several international journals of plant biology, including Planta,
Journal of Experimental Botany, and Plant & Cell Physiology. He has also organized
numerous symposia in Italy and elsewhere in Europe. Through review articles, the
popular press, and other avenues for educating the public and politicians, Sandro
has been a strong proponent and ambassador for plant biotechnology issues in Italy
and the EU.
Dennis R. Hoagland Award
This monetary award, established by the Society in 1985 with funds provided
by the Monsanto Agricultural Products Company, honors Dr. Dennis R. Hoagland,
recipient of the first Hales award, for his outstanding contributions and leadership
in plant mineral nutrition. The award, to be made not more frequently than triennially,
is for outstanding plant research in support of agriculture.

The 2006 winner is...
Dennis
Gonsalves
USDA-ARS-PWA
Dennis Gonsalves has distinguished himself among academic scientists in many
areas, including research, teaching, and technology transfer. Most well known
to the scientific community is Dr. Gonsalves's involvement in the development
and commercialization of the first genetically engineered fruit crop, papaya.
This endeavor involved leadership not only in distinguished plant science research
directed toward solving an important crop production problem, but also in assuring
that these accomplishments passed regulatory scrutiny and were accepted by and
transferred to the farming community. A theme common to all his activities over
the years has been the improvement of the situation of small farmers, especially
those from underdeveloped countries.
The early work of Dr. Gonsalves focused on plant viruses-attempting to identify
solutions to control viral diseases in crop species. In the early 1990s he expanded
his research to include controlling disease caused by papaya ringspot virus,
which threatened the papaya industry in Hawaii. At a time when transformation
efforts were in their infancy, Dr. Gonsalves successfully led an inter-institutional
research team that was able to obtain engineered papaya lines with durable viral
resistance.
After this technical success, a number of other hurdles had to be resolved
before commercial success could be achieved. Dr. Gonsalves orchestrated the
deregulation of the engineered papaya varieties for commercial use, which involved
demonstrating consumer (FDA) and environmental (EPA) safety, as well as field
evaluations (USDA). He negotiated freedom-to-operate agreements from several
corporate, university, and government patent holders so that the varieties could
be commercialized-no small feat as anyone involved in these activities will
recognize.
The culmination of this work was the commercialization of the world's first
genetically engineered fruit crop and the end of the dramatic decline in papaya
yield that occurred between the outbreak of the disease in 1992 and availability
of the transgenic varieties in 1998. During the period from 1998 to 2001, after
the new varieties were introduced, papaya yields increased by 50 percent over
the lowest yields experienced in 1998. Dr. Gonsalves's efforts did not stop
with helping Hawaiian farmers. With the support of USAID, he began to develop
locally adapted papaya varieties for Africa and Bangladesh-efforts aimed at
alleviating vitamin A deficiency in those countries.
Perhaps most pertinent to this award is not Dr. Gonsalves's personal accomplishments
in plant research, although these are clearly exceptional, but what he has accomplished
indirectly by setting an example that demonstrates the role academic scientists
can play in the production and adoption of genetically engineered crops to improve
agriculture and human health.
Dr. Gonsalves's contributions to agriculture are direct, obvious, and profound.
Not only has he provided critical leadership that led to a product of importance
in agriculture and human health, but his efforts did not stop there. He made
sure the product he developed passed appropriate regulatory hurdles to ensure
that it would have a positive impact on the papaya industry, not only in Hawaii
but elsewhere in the world.
Excellence in Teaching Award
This award was initiated in 1988 to recognize outstanding teaching in plant biology. It is an award to be made not more than triennially in recognition of excellence in teaching, leadership in curricular development, or authorship of effective teaching materials in the science of plant biology.
Excellence in Teaching Award Committee

Roger
Hangarter
Indiana University
Roger Hangarter is the 2007 ASPB Excellence in Teaching Award recipient. Roger
has been selected to receive this award because of his strong commitment to
undergraduate and graduate education and his remarkable contribution to engaging
students of all ages in the biology of plants. He not only maintains an active,
internationally recognized research program, but also serves as an excellent
teacher and inspiring mentor. He has developed the Plants in Motion
website, which has allowed numerous educators to show their students the fascinating
growth and topic movements of plants. This website has been cited in numerous
articles and journals, including Science. In addition, Roger developed,
together with Dennis DeHart, sLowlife, an art installation including
video pieces, live plants, prints, and pieces created from plants and fungi.
This exhibit has been presented at Indiana University and the United States
Botanic Garden in Washington, DC, serving as a broad educational outreach tool.
Roger also developed Plant Dance, an interactive exhibit about plants
for children. Plant Dance has been on display in St. Paul, Minn., Durham, N.C.,
and Berkeley, Calif., and
continues to travel throughout the country. Roger created Return of the 17-Year
Cicadas, a short film documenting the 17-year cicada emergence in 2004. The
film won the Science and Engineering Visualization Award from NSF and the journal
Science. Lastly, Roger has contributed plant time-lapse movies to educational
agencies and exhibits in various nations.
We in the plant community owe a debt of gratitude to Roger for providing all
of us with the tools to excite our students and for showing the public the dynamic
life of plants. He is a tireless advocate for plant biology and plant biologists.
Martin Gibbs Medal
The Martin Gibbs Medal was instituted by the Society's executive committee
in 1993 to honor Martin Gibbs, editor of Plant Physiology from 1963 to 1992.
The Gibbs Medal is presented biennially to an individual who has pioneered advances
that have served to establish new directions of investigation in the plant sciences.
The winner will receive the medal and will be invited to convene a Martin Gibbs
Medal Symposium at the annual meeting the following year.

Richard
A. Jorgensen
University of Arizona
Richard A. Jorgensen has been awarded the 2007 Martin Gibbs Medal for his pioneering
work leading to the discovery of RNA interference (RNAi). The work on cosuppression
and epigenetic gene silencing, conducted in plants by Rich and his coworkers,
significantly contributed to the present understanding of the scientific and
practical importance of RNAi. For several years following the initial publication
on cosuppression by Napoli, Lemieux, and Jorgensen (Plant Cell 2: 279289
[1990]), Rich was the leading spokesperson for the diversity of RNAbased regulatory
mechanisms in plants. Subsequent mechanistic studies in diverse plant, animal,
protist, and fungal species established the universality of these mechanisms.
The seminal contributions to this field made by the Jorgensen laboratory over
the past 17 years make him particularly deserving of the high level of recognition
bestowed by the Martin Gibbs Medal.
Cosuppression, as first described and defined by Napoli et al. (1990), is the
reduction of endogenous host gene expression resulting from attempts to overexpress
the homologous transgene. This seminal work demonstrated that cosuppression
required homology between coding sequences and that the epigenetic state was
not heritable in the absence of the inducing transgene. Over the years, the
term cosuppression was first replaced by mechanistic terms such as posttranscriptional
gene silencing (PTGS) and now RNAi. Rich developed petunia as the model system
for his cosuppression experiments because it offered convenient, elegant flower
pigmentation pattern phenotypes, which were useful for distinguishing the sometimes
infrequent epigenetic events. One very important observation was that silencing
of chalcone synthase occurred at strikingly different efficiencies and produced
a variety of flower color patterns depending on the nature of the transgene
construct. Rich and his coworkers made the critical observation that constructs
not engineered for overexpression were only competent to induce RNAi if the
transgene was integrated in the genome as an inverted repeat, leading directly
to our current understanding of the importance of double-stranded RNA in RNAi.
Rich was quick to recognize the potential significance of systemically transmitted
RNA in an information superhighway. He proposed that the capacity
of
plants to traffic RNA via the phloem and plasmodesmata, taken together with
the ability of RNA to imprint homologous DNA in a cell-, tissue-, or organ-specific
manner, might store information in chromatin about the developmental and physiological
history of the plant. This stored memory could conceivably be modified, reprogrammed,
or reset by new information.
The impact on biology, agriculture, and medicine of these new concepts will
surely continue to expand over the coming decades. Richs pioneering contributions
in this area are clearly reflected in the literature and underlie the diverse
array of biological roles played by RNAi. He has influenced the field far beyond
his key publications and review articles. The medical implications of RNAi are
only just beginning to be exploited, including potential therapies for viral
infections (e.g., hepatitis-C, HIV), degenerative diseases (e.g., macular degeneration,
ALS, and type II diabetes), and cancer (e.g., HIV-related lymphoma). These potential
benefits to mankind began with Rich and his colleagues careful and insightful
observations of fundamental genetic mechanisms in petunia.
Stephen Hales Prize
This award honors the Reverend Stephen Hales for his pioneering work in plant
biology published in his 1727 book Vegetable Staticks. It is a monetary
award established in 1927 for a scientist, whether or not a member of the Society,
who has served the science of plant biology in some noteworthy manner. The award
is made annually. The recipient of the award is invited to address the Society
on a subject in plant biology at the next annual meeting.

Peter
Quail
University of California, Berkeley
Peter Quail has made seminal contributions to elucidating the molecular mechanisms
of phytochrome action and red-light phototransduction. These studies were
initiated during his postdoctoral studies in the Biologisches Institut at the
Universität Frieburg and continue to this day in his current positions as research
director of the Plant Gene Expression Center and professor in the Department of
Plant and Microbial Biology, University of California at Berkeley. Peter has also
mentored numerous scientists, served on national scientific panels and the editorial
boards of plant journals, and worked with the Rockefeller Foundation to advance
plant biotechnology in underdeveloped countries.
Peter initially employed biochemical and physiological approaches in the study
of phytochrome, which culminated in purification of the intact protein and for the
first time allowed an accurate assessment of the protein’s spectral properties. Peter
and co-workers then launched the modern era for molecular genetic analysis of
phytochromes by cloning and sequencing the first PHY gene. It was not long before
he showed that phytochromes exist as a family of photoreceptors and began to
unravel their varying regulatory roles in plant growth and development by employing
an increasingly wide-ranging set of biochemical, molecular, genetic, and genomic
approaches.
In recent decades Peter has expanded his studies beyond the photoreceptors
to elucidate key components in the phototransduction pathway. These studies
have resulted in paradigm shifts in our understanding of how transcriptional and
post-transcriptional regulatory mechanisms operate in plants. Significant here
were the discovery of COP1 and the central role it plays in repressing photomorphogenesis,
the uncovering of the transcriptional network regulated by phytochrome,
and the identification of the phytochrome-interacting transcription-factor
PIF3. The PIF family of transcription factors is a central component of the current
model for phytochrome signaling, in which light-activated phytochrome
translocates into the nucleus and then directly interacts with transcription factors
to activate target genes.
For these achievements, ASPB recognizes Peter with the 2008 Stephen Hales Award.
Early Career
The Early Career was instituted by the Society's executive committee
in 2005 to recognize outstanding research by scientists at the beginning of
their careers. This award is a monetary award made annually for exceptionally
creative, independent contributions by a member of the Society who is not more
than five years post-Ph.D. on January 1st of the year of the presentation.

Ping He
Massachusetts General Hospital/Harvard Medical School
Ping He is an exceptionally talented and creative young scientist who has already
demonstrated his productivity in diverse areas of plant biology. Ping started his scientific
career under the guidance of Professor Lihuang Zhu in the Institute of
Genetics in the Chinese Academy of Sciences. His work on pollen culture and QTL
mapping in rice not only resulted in an impressive number of first authored papers
but also contributed significantly to the rice genome project as a whole. As a PhD
student in Professor Jian-Ming Zhou’s laboratory at Kansas State University, Ping
completed three research projects using wheat, tomato, and Arabidopsis on topics
that ranged from allopolyploidy alteration of gene expression to innate immunity.
Building upon his graduate studies on type III effectors in the bacterial pathogen
Pseudomonas syringae, Ping joined Professor Jen Sheen’s laboratory at
Massachusetts General Hospital. A combination of using a protoplast-based assay
system and Ping’s talent, vision, and pioneering spirit resulted in the discovery that
two P. syringae type III effectors, AvrPto and AvrPtoB, block FLS2-mediated
immune response signaling by targeting the FLS2-associated transmembrane
receptor kinase BAK1, promoting pathogenicity. These results help to explain the “gene-for-gene” hypothesis for host response and non-host resistance. Ping’s
accomplishments are described by his current mentor as being of fundamental
impact and others as spectacular and spearheading transformative research on the
molecular mechanisms underlying the plant immune response. Beyond his own
accomplishments, Ping also maintains many collaborative efforts in and outside his
lab and contributes generously to the success of these projects. His current effort
and long-term goal is to examine the interaction between calcium-dependent protein
kinases and MAPKs in various stress response signaling pathways. It can be
expected that Ping will continue to conduct outstanding research fueled by his
energy, curiosity, passion, and dedication.

Steven
Huber
University of Illinois
In awarding the Lawrence Bogorad Award for Excellence in Plant Biology Research
to Steve Huber, we recognize a pioneering researcher in photosynthesis and plant
metabolism. Over his 30-year career, Steve has to his credit a remarkable series
of novel discoveries and breakthrough contributions that have led the way in
shaping our current understanding of the intersection of leaf nitrogen metabolism
and photosynthetic carbon metabolism. In particular, Steve is a world authority
on the mechanisms of protein modification in plant enzyme regulation and signal
transduction. While his various projects connect through the mechanisms of protein
modification, they are diverse in the sense of investigating a wide range of
important agricultural issues ranging from the control of seed composition,
to stressassociated signaling, to the mechanisms of hormone action. A key to
the exceptional long-term success and prominence of Steve’s science is
that as his research projects mature and the underlying mechanisms are revealed,
he moves fearlessly on to the next system and the next question that will drive
the next step in understanding the control and mechanism of leaf CN metabolism.
Steve brings the type of focus and adventurous spirit to his science as was
exemplified in the extraordinary career of this award’s namesake. Steve has never
been afraid to tackle a difficult problem, and he always makes significant progress.
Indeed, the breadth of his success can be measured in several tangible ways,
including his recognition as an ISI Highly Cited author, designating him as one of“the world’s most influential researchers.” Further demonstration of research
impact is whether the work has led to textbooks being rewritten, and Steve’s
research has done just that. His seminal work elucidating the regulatory mechanisms for sucrose synthesis and nitrogen metabolism changed our basic understanding
of both carbon and nitrogen metabolism in plants. These concepts are
now an integral part of undergraduate and graduate plant physiology and biochemistry
textbooks. For example, Professor Hans Heldt notes that his 2005
Academic Press Plant Biochemistry text highlights “the findings of Steve Huber on
the regulation of sucrose phosphate synthase and nitrate reductase.”
Steve is in the midst of a truly exceptional scientific career in plant biology.
In addition to his scientific achievements, he is a dedicated mentor of students
and postdocs, a valued colleague and adviser, and an unselfish promoter of the
discipline. For these many contributions and achievements, Steve Huber is a
very deserving recipient of the 2008 Lawrence Bogorad Award.

Student Prize Committee
The 2008 winners are:
Colleen Doherty
Michigan State University
Colleen is a PhD student at Michigan State University in the laboratory of Mike
Thomashow. Colleen’s dissertation research focuses on understanding how plants
respond to cold stress. Her work focuses on characterizing the regulation of CBF2,
an important cold-responsive transcription factor. Colleen is also interested in identifying
and characterizing novel cold-response pathways that are independent of
the CBF genes. Her studies of transcriptome changes during cold stress have incorporated
computational approaches to model a cold-responsive transcriptional network.
Her research findings are providing a detailed understanding of the transcriptional
changes that plants undergo in response to cold stress. Colleen hopes to
improve her computational skills and has a long-term goal of modeling plant
responses to multiple environmental stresses. In addition to exceptional research
promise, Colleen also shows great promise as a teacher; she has been a talented
mentor to a number of undergraduate students. She is also an active member of
ASPB, currently serving as a student ambassador and as the graduate student representative
on the Membership Committee.
Tracie Hennen-Bierwagen
Iowa State University
Tracie is a PhD student at Iowa State University in the laboratory of Alan Myers.
Tracie’s dissertation research uses a biochemical approach to identify and characterize
protein complexes involved in starch metabolism. Multiple isoforms of starch
biosynthetic enzymes are found in plants, and these have been previously postulated
to function in multi-subunit enzyme complexes. Tracie’s research provides the
first direct evidence for the existence of these enzyme complexes. She has successfully
reconstituted some complexes from recombinant proteins, and she is making
use of mutant maize lines to determine the function of specific isoforms in enzyme
complex assembly. Tracie is the first author on a paper in Plant Physiology that
describes some of this work. She also has a passion for teaching: She served as an
organizer for an introductory lab course for new graduate students at Iowa State
and has mentored undergraduates and high school teachers. Finally, her talents
extend beyond plant biology; for several years she has served as an instructor in
an honors seminar course at Iowa State entitled “Tolkien’s Mythology.”
Charles "Chip" Hunter III
University of Florida
Chip is a PhD student at the University of Florida in the laboratory of Karen
Koch. His dissertation research revolves around characterization of cell wall
biosynthesis enzymes. Specifically, he has been interested in understanding the
roles of two distinct subfamilies of the cellulose synthase superfamily in maize.
Chip has used reverse genetics to identify Mu transposon insertions in members
of the CslA and CslD gene families. This effort has required that he develop and
optimize methods for PCR-based screening of DNA pools isolated from the
UniformMu population. He has developed standardized methods for these
screens that are being used by teams of undergraduates. He has successfully
identified insertions in several Csl genes and is in the process of characterizing
them. His work promises to provide important information about cell wall
biosynthesis. Chip is developing excellent teaching and leadership skills. His
dedication to public outreach and education is apparent from his activities in
mentoring undergraduates and working with high school science teachers. He
ultimately hopes to use his research expertise working toward crop improvement
in an industrial setting.
Michael A. Grillo
Michigan State University
Michael is a PhD student at Michigan State University in the laboratory of Tao
Sang. His research focuses on understanding the genetic mechanisms underlying
adaptation, using wild rice as a model. He has used QTL mapping to identify and
map QTLs that control a number of important adaptive traits. He is now focused
on identifying the genes responsible for flowering time QTLs. Mike is collaborating
with scientists at the Central Rice Research Institute in India (CRRI) to develop field
sites that will allow him to examine how individual traits in wild rice species have
contributed to local adaptation to specific environments. Mike also has a passion
for teaching and outreach. He has served as a teaching assistant in several classes,
and while he was an undergraduate he served as the director of the MSU organization
Science Theater, which presented entertaining science demonstrations to the
public. Mike hopes to continue his career in research as a university professor
studying mechanisms of plant adaptation to diverse environments.
Ajay Sandhu
University of Nebraska
Ajay is a PhD student at the University of Nebraska–Lincoln in the laboratory
of Sally Mackenzie. His dissertation research focuses on mitochondrial biology.
To examine the effect of destabilizing the mitochondrial genome, Ajay used RNAi
to down-regulate the expression of MSH1, a nuclear gene that functions
to maintain mitochondrial genome stability. Remarkably, down-regulation of MSH1
resulted in an array of phenotypes that was conserved in several different plant
species. Ajay found male sterility, leaf variegation, and plant stunting, each
associated with a specific mitochondrial genome rearrangement. He also identified
a mitochondrial genome rearrangement associated with heat tolerance. This research
resulted in a first-author publication in PNAS last year. Ajay’s
research may lead to the development of new approaches for inducing cytoplasmic
male sterility, an important and poorly understood agronomic trait. Ajay hopes
to ultimately conduct research in an agricultural industry.
