Oryza brachyantha

About Oryza brachyantha

Oryza brachyantha is a distant relative of cultivated rice. It is placed on the basal lineage of Oryza and is the only member of the genus assigned to the F genome type. An annual or weekly perennial tufted grass, it is distributed in west and central Africa, and grows in open wetland habitats. It has potentially useful traits for rice breeding, including resistance/tolerance to yellow stem borer, leaffolder, whorl maggot and bacterial blight. The O. brachyantha reference sequence will provide an important resource for functional and evolutionary studies in the genus Oryza. Its nuclear genome is diploid (2n = 24) and ~362 Mb.

Users are encouraged use these data to advance their research on individual loci but are asked to respect the rights of the investigators who generated these data to publish the whole-genome level description of the O. brachyantha in a peer-reviewed journal. This description includes whole-genome comparative analyses, genome size evolution, gene family evolution, gene organization and movement, heterochromatin, centromere evolution.
