Tien C. Tso - Inducted 2005
Tien C. Tso joined ARS in 1952 and retired in 1983. He was a leader in
laying the foundation of organic metabolism of phytochemistry: the roles of
organic compoundssuch as sugars, organic acids, amino acids, sterols and
polyphenolsin plants, and their metabolism in the plants. His research
findings have broad applications. For example, he developed a group of fatty
acid compounds that are widely used in the fruit and flower industries for
thinning purposes. Much of his work supports medical and nutritional uses of
tobacco plant constituents. In the early 1990s Tso played a key role in
establishing a scientific team that helped resolve a major wheat trade issue
between the United States and China, resulting in increased U.S. wheat exports
to China.

Wayne W. Hanna -
Inducted 2006 ![Camera: Link to video](littlecam2.gif)
In Wayne Hanna's 35 years of research in turfgrass breeding and genetics, he
has improved the very surface of the earth we walk on. His bermudagrass
varieties have more vigor and resistance to pests and heat and need less
fertilizer, pesticides and water. His bermudagrasses are widely used for forage
and on golf courses, ball fields and lawns. He developed new pearl millets for
forage that cost farmers less to grow while producing higher yields of
high-quality pasture. Hanna's seminal research on apomixis (plant cloning) is
directed towards producing true-breeding cultivars that retain superior
characteristics and hybrid vigor in crops for which traditional hybridization
is not economically feasible and in which apomixis does not occur naturally. He
has also done vital work on gene transfer in millet. Hanna was based at the ARS
Coastal Plain Experiment Station, Tifton, Ga.

Ray D. Jackson -
Inducted 2006 ![Camera: Link to video](littlecam2.gif)
The "Father of Remote Sensing," physicist Ray Jackson developed
methods used worldwide to evaluate crop health. His methods provide quick,
inexpensive, noninvasive assessments of plants and soils. Jackson's insight was
to determine directly from plants what their condition wasby observing
the difference between their remotely sensed "body temperature"
(emitted infrared radiation) and that of the air and soil. Jackson's crop-water
stress index better detects yield-robbing crop stress and can indicate when to
irrigate. Because of his work at the ARS U.S. Water Conservation Laboratory in
Phoenix, Ariz., commercial sensors soon became available. The technology
expanded to use of airplane/ground systems and then orbiting satellites. Today,
remote sensing of vegetation condition is commonplace around the world

Vernon G. Pursel -
Inducted 2006 ![Camera: Link to video](littlecam2.gif)
Vernon Pursel is recognized worldwide for reproductive and genetic
technologies in farm animals. His influence on gene engineering and his
development of frozen swine semen profoundly influence animal and biomedical
science. Freezing of swine semen for artificial insemination was unsuccessful
until the 1970s when Pursel developed a procedure that is used to this day.
Advances resulting from his research have increased use of artificial
insemination to include over 80 percent of the U.S. swine herd. In 1984, Pursel
was the first to successfully transfer foreign genes into farm animals. His
centrifugation technique made methods used in mouse experiments possible in
pigs and cows, and he proved gene transfer is practical in farm species.
Transgenetic technology promises better animal growth and milk production,
enhanced disease resistance and higher quality food, as well as inexpensive
farm production of human medicines.

Dennis Gonsalves -
Inducted 2007 ![Camera: Link to video](littlecam2.gif)
Dennis Gonsalves was a trailblazer in applying pathogen-derived resistance
to the development of virus-resistant plant varieties and in related research
into viral diseases of fruits and vegetables. After years of studying and
improving disease resistance in cucumber, grapevine and other fruits and
vegetables, he and his research team developed methods for transferring
specific virus genes into host plants to create resistance to that virus. His
ringspot-resistant papaya saved the small-farm-based Hawaiian papaya industry.
This new variety was so successful that it became the first commercialized
transgenic fruit crop. Gonsalves further adapted papaya varieties for local
conditions in Africa and Bangladesh. These improved varieties will help in
overcoming vitamin-A deficiency in children of those areas.

Johnie N. Jenkins -
Inducted 2007 ![Camera: Link to video](littlecam2.gif)
Plant geneticist Johnie Jenkins' realization of interdisciplinary teamwork
on host plant resistance brought great advances in reduction of damage to
cotton by insects and nematodes. Investigating differences in germplasm
resistance to pests, he pioneered the understanding of the effects of chemical
differences among cotton strains on the variability of damage done by pests.
Cotton farmers can thank Jenkins for less damage by boll weevils,
Heliothis, tarnished plant bugs, and root-knot nematodes. Jenkins also
performed seminal work on cotton fruiting, retention, and yield, developing the
technique of "plant mapping."

Janet C. King - Inducted 2007
![Camera: Link to video](littlecam2.gif)
Janet King, a nutrition scientist, is internationally recognized for her
research on energy and zinc metabolism in adults, and especially in pregnant
women. Her work has profoundly influenced our understanding of maternal and
infant health. She showed in a groundbreaking study that maternal nutritional
statusparticularly fat storesat the inception of pregnancy strongly
affects the pregnancy's outcome. This led to the Institute of Medicine of the
National Academies establishing differing weight-gain guidelines fior
underweight, normal-range and overweight expectant mothers. King chaired the
2005 Dietary Guidelines Advisory Committee for the U.S. Departments of
Agriculture and Health and Human Services, which guided revision of the Dietary
Guidelines for Americans and the Food Pyramid. She also chaired the National
Academy of Sciences' Food and Nutrition Board, which established a new paradigm
for U.S. Dietary Reference Intakes, and a United Nations committee on
international harmonization of dietary standards.

Robert E. Davis - Inducted 2008![Camera: Link to video](littlecam2.gif)
Plant pathologist Robert Davis's 1979 discovery of spiroplasmas, a
previously unrecognized form of life, revolutionized the worlds of plant
pathology, medicine, and animal husbandry. The fundamental understanding of
this entire group of lifeforms rests on his work. A form of bacteria without
cell walls, spiroplasmas cause diseases of crop plants and of insects and are
suspected in some human maladies. By showing the scientific world that this
lifeform exists, Davis opened new categories of research. He showed the
scientific community how to culture these smallest of microbes and how they
survive outside plants on flower petals. Davis developed techniques to detect
and identify spiroplasmas, and discovered spiroplasma diseases of honey bees
and other pollinating insects. He conceptualized and led the project to
sequence the spiroplasma genome. Davis even discovered a pathogen of the
pathogena virus that infects spiroplasmas across species.

Andrew N. Sharpley - Inducted 2008![Camera: Link to video](littlecam2.gif)
Soil scientist Andrew Sharpley is internationally recognized for his
invaluable contributions in promoting soil and water conservation strategies
that are both economically beneficial and environmentally sound. Sharpley's
research on non-point-source pollution led to involvement in developing
Comprehensive Nutrient Management Plans that increased recreational use of
waters, improved shellfish harvests, reduced fish kills, and lowered drinking
water treatment costs. Sharpley's research on nutrient cycling in soil-water
systems demonstrated the movement of nutrients in agricultural systems and
their impact on water resources. This led to equations that predict the
transport of elemental nutrients in runoff, including the Phosphorus Index
(widely known as the "P Index") for identifying agricultural fields
at greatest risk for nutrient loss. The P Index serves as an educational tool
that shows the results of management options to provide flexible strategies for
keeping nutrients in the field and out of surface and ground water. Sharpley's
research recommendations and technological innovations have been widely adapted
by regulatory and resource conservation agencies worldwide.
