RAPID: Initial Development of Rice Genetic Stocks with African Germplasm for Crop Improvement and Functional Genomics

PI: Georgia C. Eizenga（阿肯色大学/USDA-ARS Dale Bumpers国家水稻研究中心）CoPI: Paulino L. Sanchez（亚利桑那大学）西非栽培稻（Oryza glaberrima）及其祖先品种O. barthii是作物改良中几个重要性状的来源，包括抗虫性、耐旱性、幼苗活力、杂草竞争、对有毒土壤的耐受性、粮食品质和粮食产量。为了扩大水稻分子遗传学进展的影响，需要在适应美国的亚洲水稻（O. sativa）品种的背景下开发用于翻译基因组学工作的水稻种子库。该RAPID项目将产生急需的基因型遗传资源，包括回交自交系（BILs）和高级回交（ABC）定位群体，使用三种选择的O. glaberrima和O. barthii作为供体亲本，与美国水稻品种LaGrue和M-202结合。这些种子储备也将作为水稻育种者的资源，将光斑稻和barthii稻中发现的非生物和生物抗逆性结合起来。进入他们的高级繁殖品系。所有种子库存将通过USDA-ARS遗传库存-稻谷（GSOR）收集（斯图加特，AR）进行分发。所有基因型信息将通过AGI网站（www.genome.arizona.edu）在线提供。除了产生的资源影响之外，该项目还将为博士后研究员提供培训，他们将在管理合作研究项目的各个方面得到指导。为了鼓励下一代植物科学家和育种家，该项目将参与戴尔邦珀斯国家水稻研究中心和阿肯色大学水稻研究和推广中心现有的推广项目。最后，该项目还将参与亚利桑那大学本科生物学研究计划（UBRP），该计划与全州社区学院有联系，并为少数族裔提供目标资金。该项目还将受益于与国际热带农业中心（CIAT）的合作，该合作将开发以南美水稻品种为背景的O. glaberrima和O. barthii的遗传资源。

PI: Georgia C. Eizenga (University of Arkansas/USDA-ARS Dale Bumpers National Rice Research Center) CoPI: Paulino L. Sanchez (University of Arizona)Key Collaborator: Mathias Lorieux [International Center for Tropical Agriculture (CIAT), Colombia]West African cultivated rice (Oryza glaberrima) and its progenitor species, O. barthii, are a source of several traits important in crop improvement including pest resistance, drought tolerance, seedling vigor, weed competition, tolerance to toxic soils, grain quality and grain yield. To expand the impact of the advances being made in rice molecular genetics, rice seed stocks need to be developed for translational genomics efforts in the background of Asian rice (O. sativa) cultivars adapted to the USA. This RAPID project will generate critically needed genotyped genetic stocks that include both backcross inbred lines (BILs) and advanced backcross (ABC) mapping populations using three selected accessions of both O. glaberrima and O. barthii as the donor parent with US rice cultivars LaGrue and M-202. These seed stocks will also serve as a resource for rice breeders to incorporate the abiotic and biotic stress resistance found in O. glaberrima and O. barthii. into their advanced breeding lines. All seed stocks will be distributed through the USDA-ARS Genetic Stocks - Oryza (GSOR) Collection (Stuttgart, AR). All genotypic information will be available on-line through the AGI web site (www.genome.arizona.edu). Beyond the impact of the resources generated, the project will provide training for a post-doctoral researcher who will be mentored in all aspects of managing a collaborative research project. To encourage the next generation of plant scientists and breeders, the project will participate in existing outreach programs at the Dale Bumpers National Rice Research Center and the University of Arkansas Rice Research and Extension Center. Finally, the project will also participate in the University of Arizona Undergraduate Biology Research Program (UBRP) which has links to statewide Community Colleges and targets funds for minorities. The project will also benefit from a collaboration with the International Center for Tropical Agriculture (CIAT) that will develop genetic stocks with O. glaberrima and O. barthii in the background of South American rice cultivars.
