Summary Program Rationale
Crop yields are increasing by approximately 1 percent per year in the USA.
This increase is the result of coordinated advances in plant genetics, crop
science and agronomy, crop protection, soil science, agricultural engineering,
and global carbon dioxide increases. As good as this record is, though, it is
unlikely to keep pace with increases in world food demand over the next 2 to 3
decades. In addition, it is clear that quality, safety, diversity, and security
of the food supply must be improved even as production is increased. Better food
safety and security, crop protection, crop yield, and crop quality are immense
and difficult problems whose solutions require fundamental scientific
breakthroughs.
Often, when complex problems seem to defy solution, new approaches are
needed. New approaches, however, require new knowledge. These gaps are filled by
this program of fundamental, long-term targeted research. The importance of a
long-term, fundamental research program is highlighted by current advances in
agriculture. Many of today's exciting developments are based upon yesterday's
fundamental research, most prominently molecular biology and genetic
engineering. Bioengineered herbicide-resistant crops, for example, are
revolutionizing the way in which herbicides are used, offering not only better
weed management, but also conferring significant benefits to the environment.
New molecular technology is increasing the scope and the pace of plant breeding.
Soon, one or more plant genomes will be completely sequenced, providing access
to any gene in that DNA and enabling the identification of similar genes in
other plants. The benefits of this advance have barely been tapped.
The technological advances leading to today's agriculture have depended upon
knowledge of the mechanisms of biological processes, i.e., the individual steps,
as well as a more holistic knowledge of how the processes affect characteristics
of the integrated organism or plant community. Fundamental long-term research
into mechanisms creates the knowledge from which science can improve biological
processes, and thereby improve crop performance or crop characteristics. In a
real sense, this research gives the United States security of its food supply in
a hungry world. Nonetheless, fundamental long-term research, by its very nature,
is high-risk. This means the usefulness of the new approach is not known until
substantial effort is invested and new knowledge is generated. In addition, it
is by definition reductionist, with a focus on understanding systems 'one piece
at a time.' As a result, it can often be highly specialized.
Addressing these special circumstances by ARS requires organizing a national
program with long-term, fundamental research as its major theme. The Plant
Biological and Molecular Processes National Program is intended to group core
fundamental research initiatives for long-term advances in crop production,
protection, product value, and food safety. This Program will be distinguished
from other National Programs by its emphasis on knowledge of biological
mechanisms, but it will overlap considerably with other National Programs that
focus primarily on applications of knowledge to solve problems. Thus, the Plant
Biological and Molecular Processes Program will be important both to those who
depend upon generation of new fundamental knowledge, and to those who aim to see
that knowledge put to use to solve agricultural problems. Through close
associations with other national programs that are more product-oriented, the
Plant Biological and Molecular Processes National Program will identify
innovative possibilities and work to turn these into reality.
