San Diego, California
January 17, 1999The U.S. Department of Agriculture announced here today that it
will establish a new gene data research center at Cornell
University in Ithaca, N.Y. USDA also will acquire eight new automated machines
allowing the department's researchers to speed their analyses of plant, animal and
microbial genes, said Judy St. John. Based in Beltsville Md., she is Associate Deputy
Administrator for Crop Production, Product Value and Safety with USDA's Agricultural Research Service.
"Together, these two initiatives will accelerate genetic discoveries to benefit our
agriculture, food supply, environment and consumers," St. John said at the Plant and
Animal Genome VII Conference held today through Jan. 21 at San Diego's Town and Country
Convention Center.
"The new DNA analyzers are very fast, highly automated machines," St. John said
at a conference workshop on federal funding of plant gene research. "These
state-of-the-art tools will make USDA's Agricultural Research Service the single most
powerful force in genome sequencing within the public agricultural research sector."
The analyzers should begin arriving this spring at ARS labs in California, Florida,
Georgia, Iowa, Maryland, Nebraska, New York and Pennsylvania.
ARS will operate the new Center for Bioinformatics and Comparative Genomics at sites in
Ithaca and Geneva, N.Y., where ARS already has research labs, St. John said.
Genomics is the study of the genome, which refers to essentially all the
genetic material of an organism. Bioinformatics is the use of computers
to help researchers answer life-science questions, mainly through studying genetic
information in electronic databases.
"The USDA-funded center at Cornell," she said, "will aid researchers around
the country and the world in the quest to discover all the genes in grains--like corn,
wheat and rice--and plants in the family that includes tomatoes,
potatoes and peppers."
"ARS and Cornell," she said, "already maintain the foremost computerized,
publicly accessible data bases for information about the structure of genes in grain
crops and the Solanaceae family that includes tomatoes, potatoes
and peppers. The center will establish a new partnership
to strengthen this effort."
"This partnership will bring in the expertise of Cornell's computer theory center to
apply advanced computer tools to analyze gene information. This research is urgent,
because databases are required that can handle the deluge of information these gene data
banks will receive as a result of increased federal funding of gene-sequencing
projects," St. John said.
Once a gene's structure is discovered, scientists can use computers to look for similar
structures in genome databases of plants, humans, mice and other life forms.
Similar structure often connotes similar function, thus shortening the time to find out
what job a gene performs. And once a gene's function, such as disease-resistance, is
identified, biotechnologists can begin experiments to see if that gene can be re-built to
make it more effective.
Plants with improved resistance to disease, for example, should require less chemical
pesticides. Or, the genes could be moved into plants that currently lack resistance.
St. John said plans for the Center for Bioinformatics and Comparative Genomics at Cornell
will be implemented through increased ARS funding, with the addition of several ARS
bioinformatics specialists. Cornell faculty in the Department of Plant Breeding and
Biometry and the Cornell Theory Center will
join the ARS staff in the new genomics center.
ARS bioinformatics specialists and Cornell faculty in the Plant Breeding and Biometry
Department currently maintain the gene data banks known as GrainGenes, SolGenes (for
solanaceous crops) and RiceGenes.
The ARS labs receiving the new DNA analyzers are in Albany, Calif.; Ft. Pierce, Fla.;
Athens, Ga.; Ames, Iowa; Beltsville, Md.; Clay Center, Neb.; Orient Point, N.Y.; and
Wyndmoor, Pa.
"The machines will greatly accelerate the speed at which the researchers discover the
structure of genes of plants, farm animals and other living things, such as microorganisms
important in food safety," St. John said.
At ARS' Plum Island Animal Disease Center in Orient Point, N.Y., scientists will use the
new instrument to detail the genetic makeup of microbes deadly to livestock.
"Discovering the genetic structure of those microbes," said St. John,
"could enable researchers to develop new, more
effective techniques to protect farm animals."
At ARS' Beltsville (Md.) Agricultural Research Center,
researchers in the Livestock and Poultry Sciences Institute will put their DNA analyzer to
work on genes important in cow mammary glands. The scientists want to find genes
responsible for resistance to diseases of the mammary
gland.
In Albany, Calif., biotechnologists will use one of the instruments at the ARS Western Regional Research Center and at the Plant Gene Expression Center operated by ARS and
the University of California, Berkeley. The scientists will examine genetic material from
microbes as well as from rice, wheat and a flowering plant called Arabidopsis thaliana, a
member of the mustard family.
"Arabidopsis has become a premier model for hastening discovery of important genes in
crop plants," said St. John. "The new DNA analyzers should enhance USDA's
contribution to international projects to sequence all the genes in Arabidopsis
and rice."
The Perkin-Elmer ABI model 3700 DNA sequencers purchased by ARS can boost a lab's
productivity an estimated 50 times and decrease costs, according to Perkin-Elmer Corp.,
Norwalk, Conn. The sequencers can run unattended for 24 hours, enabling labs to process
tens of thousands of samples a week.
ARS research on plant genomes is a critical federal component in support of the National Plant
Genome Initiative. Through research in the public and private sectors, the initiative
aims to improve plants to address regional, national and global problems. These include
problems of food supply, human nutrition and health, environmental quality, agricultural
and forestry resource
supply and quality, energy supply, and rural economies.
The NPGI is coordinated by an interagency working group of the cabinet-level National Science and
Technology Council. Federal competitive grant funds in support of the initiative come
largely from USDA, the National Science Foundation, the
Department of Energy and the National Institutes of Health.
More than 1,000 scientists and others from around the country and the world have
registered to attend the Plant and Animal Genome VII Conference. USDA is a co-sponsor
along with universities and nonprofit and industry groups.
