The National Plant Genome Initiative: Objectives for 2003–2008 THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M.Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm.A.Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V.Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M.Alberts and Dr. Wm.A.Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

The National Plant Genome Initiative: Objectives for 2003–2008 Preface Since its inception, the National Plant Genome Initiative has become both a national and international focal point for plant biologists, creating excitement for genome scientists, crop breeders and plant physiologists alike. The diverse interests of the plant biology community, whose members work on more than 100 different plant species of economic, agricultural, or purely scientific concern, have converged on the enabling potential of plant genomics. Both the Arabidopsis genome project and the NPGI have leveraged important ties to the international plant biology community to further the field as a whole. This community needs now to exploit the power of “complete” genome sequences, such as the finished sequence of Arabidopsis thaliana, and more recently, the draft sequence of Oryza spp. (rice) to make basic discoveries about plant biology, and to translate these into agricultural use. Additionally, we are poised to determine the genomic DNA sequence of several judiciously chosen additional species, as detailed in this report. There are several reasons why complete genome sequences are powerful enabling tools for discovering how genes, cells, organisms and populations function: First, because all plants have basic similarities, one can use “model” and “reference plants” with well-documented genetic features to make educated assumptions about similar features in many other species. That gives all plant biologists a head start on

The National Plant Genome Initiative: Objectives for 2003–2008 understanding any application in their particular crop or plant of interest. Second, the ability to specifically manipulate a plant’s genetic building blocks permits us to make directed changes in its physiology. While that detailed knowledge is essential, genomics gives us a different perspective with which to obtain it—that of the big picture—because we can access and describe the activity of all the genes simultaneously. Finally, because genomic sequence is a record of a plant’s evolutionary history, we can, using comparative methods, unravel what has occurred in the past, understand how the great diversity of plant form and function arose, and begin to direct that evolution to beneficial and ecologically sound uses in the future. As the second phase of the NPGI gets under way, it will be important to keep in mind the interdependent nature of genomics research. Complete and partial genomic sequences and their attendant genomics tools are critical resources on which community members rely for individual research projects. If everyone is to make progress, funding needs to be distributed competitively in the light of stringent peer review, and the results and resources delivered need to be of the highest-quality possible, accessible without restrictions, and provided on schedule. In other words, for the sake of all of the plant biology community, the NGPI needs to fund the best science and the most qualified representatives to undertake the work. In addition, in the rush to apply genomic approaches to uncover information in many different plants, we need to remember that rapid discovery using easily manipulated model and reference species is the most efficient tool to convey knowledge to an application-oriented user community. It is thus vital that we continue to efficiently mine the model for all of plant biology—Arabidopsis thaliana— while building our knowledge base outward from there, through the sequencing of carefully selected reference species that we define herein, and onward to all the major crop species over time. To do otherwise is to diffuse the fundamental value of genomics as a science and as an applied tool, and does not do justice to the progress made under the first round of the NPGI.

The National Plant Genome Initiative: Objectives for 2003–2008 This argument is not only supported solidly on both scientific grounds (including experience from other genome projects leading up to the Human Genome Project), it is also an economic reality. Plant genomics has made remarkable progress in a short time period with a cumulative amount of funding that simply pales in comparison to that currently available for human, mouse, invertebrate, and microbial genomics efforts. Obviously if more money were to be made available, the Initiative could accommodate a more wide-ranging set of projects to the satisfaction of many more research and commodity groups anxious to use genomics. In fact, I would argue that the competitive, peer-reviewed plant biology research funded by the NSF, DOE, USDA, and NIH is one of the best investments made by the federal government in terms of “bang for the buck,” given the importance of plant biology to our society. But, given financial constraints, it makes sense to exploit the data from the model and reference species to their fullest, recruit techniques developed in non-plant genomics projects into plant biology, capitalize on falling sequencing costs when appropriate, and continue to make careful decisions on how to build the resources that the plant biology community uses collectively. In this report, the committee on Objectives for the National Plant Genome Initiative: 2003–2008 which I chaired, makes suggestions for the next phase of the Initiative that adhere to these realities. The committee was established by the National Research Council in response to a request from the sponsors of the Initiative (OSTP, NSF, DOE, and USDA) for guidance in crafting future objectives for the program. To assist its deliberations, the committee organized a workshop at the National Academy of Sciences on June 6–7, 2002. (The agenda is attached as Appendix A). The group that participated included plant geneticists and biochemists, evolutionary biologists, bioinformaticists, and investigators who study yeast, C. elegans and human pathogens. We are particularly grateful for the time they spent in both the panel sessions and working groups. Their insights added significantly to the breadth of our thinking, and are reflected in the report.
