These pre-publication data are being released under guidelines of the Fort Lauderdale Agreement, which reaffirms the balance between fair use (i.e. no pre-emptive publication) and early disclosure. 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. nivara 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. This genome falls under the scope of the I-OMAP (International Oryza Map Alignment Project) consortium. The I-OMAP consortium is an internationally coordinated effort to create high-quality reference assemblies representing the diversity of wild and crop-progenitor species in the genus Oryza (Jacquemin et al, 2012).

About Oryza nivara

Oryza nivara is a wild rice from India; one of rice species being used in the OMAP project. It belongs to the AA genome group. Breeders are interested in this organism because it exhibits resistance to grassy stunt virus. It is found in swampy areas, at edges of ponds and tanks, beside streams, in ditches, in or around rice fields. It usually grows in shallow water up to 0.3 m. seasonally dry; in open habitats. It has 12 chromosomes and a nuclear genome size of 448Mb (flow cytometry). This work was part of the Oryza Genome Evolution project funded by NSF Award #1026200 and in collaboration with Y. Hsing (Taiwan).
