| 0 | GSOR 312013 | 'Cypress' | Oryza sativa L. | United States | GSOR |  | | 2010 | DONATED | 2011 | | | | | Genetic material | A consortium of NRI funded researchers at Colorado State University, The Institute for Genomic Research, the International Rice Research Institute, Perlegen Sciences, and the Max Planck Institute collaborated on the OryzaSNP Project that involved genome-wide single nucleotide polymorphism (SNP) discovery across a unique fraction of the rice genome. This partnership has identified SNPs from across the whole genome of 20 rice cultivars. SNPs are a marker of genetic variation between individuals of species that allow scientists to identify regions of genetic variation that may be linked. Examples of traits that might be linked include plant development, yield, disease resistance, drought tolerance, and nutritional value. Rice is the world's top food crop and principal source of nourishment for nearly half the world's population. By identifying and comparing differences in DNA sequences, the new knowledge will accelerate development of hardier, more productive types of rice, particularly for people in the poorest but fastest growing nations. The consortium released all the SNP data at a public workshop held during the 5th International Symposium of Rice Functional Genomics, October 15-17, 2007, in Tsukuba, Japan. The research team facilitated discussions with participants on how to use the many SNPs generated to forward rice genomics, genetics and breeding. | 1837896 | GSOR 312013 |

They cover the full geographic and ecological range of rice- from Indonesian paddy terraces, to the harsh upland soils of northern Thailand; from rapidly rising Chinese riverbeds to African mangrove environments. The 409 O. sativa accessions represent all five sub-populations of rice: indica, aus, tropical japonica, temperate japonica and Group V (sometimes called aromatic or basmati) varieties. The diverse set of rice accessions also includes a wide range of important economic phenotypes, including varieties known to be resistant to diseases and insects or tolerant to flooding, drought, high salt concentrations, low mineral nutrition. There are also varieties with varying cooking qualities, such as different grain colors, lengths, textures, and fragrance. The accessions were chosen to build upon several previous studies, including a subset of the varieties used by Garris et al. (2005) to evaluate sub-population structure in O. sativa. Approximately 200 of our accessions overlap with the 3,000 analyzed for diversity within the internationally-funded Generation Challenge Program (GCP) and 159 overlap with the USDA-ARS rice core collection. This Rice Diversity Panel was fingerprinted with 36 simple sequence repeat (SSR) markers and evaluated for 18 agro-morphological traits. The rice diversity panel with the accompanying genetic and phenotypic information provides a valuable foundation for association mapping, understanding the basis of both genotypic and phenotypic differences within and between subpopulations, and rice improvement programs. | 1882717 | GSOR 301093 |

The Core Collection containing about 10% of the whole NSGC Rice Collection was assembled by stratified random sampling method in 2002, evaluated comprehensively for 25 characteristics and proven to be highly representative of the whole collection. Information drawn from the Core Collection can effectively be used to assess the diversity of the whole collection with 88% certainty. A single plant was selected from each Core accession in 2006 and bulk seed from the single plant selection was produced in 2007 and deposited in the GSOR. DNA extracted from the selected plant was analyzed with one indel marker and 71 SSR (Single Sequence Repeat) markers that cover the entire rice genome about 30 cM apart. A Mini-Core Collection containing about 10% of the Core Collection was subsequently developed and genotyped through various means. Because the Core and Mini-Core were developed from single-plant selections from the NSGC accessions which may be phenotypically variable, there is the possibility that the GSOR seed sources are not exactly the same as the NSGC sources. | 1742358 | GSOR 311444 |
