Chinese complete wild rice genome map
Researchers from China’s Kunming Institute of Botany (KIB) have completed the genome sequencing and framework mapping of a wild rice, Oryza rufipogon, regarded as the wild ancestor of Asian cultivated rice. Sequence data from the 370 megabase genome covers 90% of the species’ 40,000 genes. A map of the O sativa genome, compiled from indica and japonica cultivars, was published in 2005. The completion of another rice genome map will facilitate the identification of key functional genes, help develop improved varieties and germplasm as well as boost production, the researchers say. KIB is part of the Chinese Academy of Sciences.
