Oryza AA Genomes Database

       Asian rice (Oryza sativa) is among the world’s most important crops. The genus Oryza has become a model for the study of plant genome structure, function, and evolution. We have undertaken de novo, full-genome sequence analysis of five diploid AA-genome species that are closely related to O. sativa. These species are native to quite different environments, representing four continents, thus exhibiting very different adaptations. Our studies identify specific genetic changes, in both gene copy number and the degree of diversifying natural selection, that indicate specific genes responsible for these adaptations, particularly in genes related to defense against pathogens and reproductive diversification. This genome discovery and comparative analysis provide a powerful tool for future Oryza study and rice improvement.
