2008 ANNUAL REPORT Seed Biotechnology Center ACADEMIC DIRECTOR’S MESSAGE he UC Davis Seed Biotechnology Center (SBC) has past decade. At UC Davis this is enabled by the Ralph M. enjoyed a steady increase in activities and personnel Parsons Foundation Plant Transformation Center established Tsince its inception 10 years ago, all made possible by the with funds originally solicited by the SBC. continuing partnership between the University of California We also worked with the seed industry to raise funds for offices and the seed industry. In particular, generous funding from and laboratories for the SBC, resulting in our location in the the California Seed Advisory Board has enabled the SBC to Plant Reproductive Biology building. In addition to the SBC, employ staff to compound that support from diverse sources. this building houses a vibrant group of plant researchers and It is not possible to review all the accomplishments of the last students, as well as the Public Intellectual Property Resource decade in this short essay, but a brief overview will illustrate for Agriculture (PIPRA). These fund-raising campaigns the impact of this ongoing collaboration. spearheaded by the SBC have paid remarkable dividends. Kent J.

The identification and mapping of these markers is particularly in Europe, and the development of a separate at our Seed greatly facilitating breeding efforts in these crops. The SBC regulatory system specifically for these crops largely stymied is centrally involved in the Chile-California Partnership for Biotechnology further commercialization in additional species. Nonetheless, the 21st Century, a program that will enhance crop variety Symposium at UC research using recombinant DNA methods has advanced our development through collaborative research and education knowledge of plant genetics and biology remarkably in the programs.

In particular, a Specialty Crops Regulatory Assistance program has A emphasized at the American Seed Research Summit organized in been developed, modeled after the IR-4 program for agricultural chemicals, cooperation with the American Seed Trade Association, the American to aid specialty crop developers through the regulatory process. The SBC Seed Research Foundation and the National Council of Commercial Plant has worked with the California Seed Association to provide scientific input Breeders. The SBC played a key role in organizing this summit and in and to educate legislators and the public about the significance of seeds and preparing a white paper to publicize its conclusions. variety improvement to agriculture. Due to the success of these programs and partnerships, the SBC is expanding its staff and taking on new projects, The SBC has taken the initiative in educating the next generation of plant guided by stakeholder feedback. breeders by establishing the Plant Breeding Academy (PBA). This program graduated 15 breeders in 2008 and another 23, including participants o celebrate 10 years of research, service and partnership, the SBC is from nine foreign countries, are currently in the second PBA class. Our Torganizing a symposium on “Seed Biotechnologies: Filling the Gap continuing education courses for seed professionals have served over 1,500 between the Public and Private Sectors” May 11-12, 2009, at UC Davis. We participants since March 2000. have invited outstanding international scientists to participate, as well as 2 In 2007, the SBC organized an international symposium on “Translational leading researchers from the University of California. We invite you to this Seed Biology: From Model Systems to Crop Improvement” that brought discussion of the latest developments in molecular and transgenic breeding, outstanding seed scientists to California to discuss application of new commercialization of new varieties, technology transfer, and educational discoveries for seed improvement. programs to meet the manpower gap in the seed industry.
