Forming a Living System. Deinococcus radiodurans
is a completely sequenced microbe capable of cleaning up environmental
pollutants in high-radiation enviornments. Understanding how it (and other
microbes) work from their roster of "parts" is the challenge of the Microbial
Cell Project. |
Future Directions
While the DOE MGP and MCP focus
primarily on environmental, energy, and biotechnological areas, it is
worth noting here that there will be spinoff applications in medicine
and agriculture as well. Potential biomedical benefits from comparative
genomics studies include insights into the specialized, shared systems
used by disease-causing organisms (pathogens) to disable or destroy human
and animal cells. Comparing these genomic data with those of other microbes
may help scientists understand a diverse range of pathogens that have
remarkably similar methods for infiltrating organisms with protein-coding
genes capable of sneaking past human, animal, or plant defense systems.
These protein structures may provide ideal targets for developing completely
new types of antibiotics for people, or new ways to protect animals and
plants from disease. Thus the MCP will have great value to other agencies
and academia, as well as to the private sector. While the MGP will continue
to sequence microbial genomes of mission relevance to DOE, its objectives
are to mine genomic information from sequenced microbes, improve tools
for annotation and analysis of sequence data, develop high-throughput
methods for determining gene function and gene expression, and develop
methods for examining protein-protein and protein-nucleic acid interaction.
The MCP, arising from the MGP, has a bolder goal, to understand a microbial
cell in its entirety. Information about the organization and functions
of the parts of a simple cell, in its limited complexity, will relate
directly to more complex cells and multicellular organisms. We also recognize
that perhaps the most significant impact of these programs will come from
the delivery of new science, new insights, and new approaches to the difficult
challenges that DOE faces in carrying out its varied and demanding missions.
The future promises many exciting
developments as the fruits of the DOEinitiated microbial genome and
microbial cell research programs mature. Already, we have become more
appreciative of the extent of the microbial world's effect on Earth, realizing
how little we know about microorganisms and wondering at their potential
benefits to our worldif only we are wise enough to discover them. Much
work lies ahead, from defining a roadmap for the MCP, with clearly delineated
deliverables and benchmarks, to assembling the teams from DOE labs and
academia, as well as the private sector, to move towards the goals of
this ambitious program. This effort will begin in the near future with
a series of workshops to define the specific components of the MCP and
build the required roadmap. DOE already is planning to coordinate and
partner with other interested federal agencies, and this will be important
to ultimate success. But the ultimate goal, critically dependent on DOE
facilities and technologies, as well as DOE's most valuable asset, her
interdisciplinary teams of first-rate scientists, is to figure out just
how a cell, in its entirety, actually works. Then biologists will have
a set of genetic building blocks, and the real adventure can beginto use
them intelligently for assembling useful and specific microbial tools
to address the nation's needs.
