Welcome to the rice genome database

The PGSB Oryza sativa database (MOsDB)

Rice plant picture

The MOsDB is a resource for publicly available sequences of the rice (Oryza sativa L.) genome. Rice is an experimental model for the cereal crops research and an agriculturally important plant, providing food for more than half of the world population. The estimated rice genome size is about 430 Mb, which is the smallest among all the cereal crops and about one seventh of human and 3.5 times of Arapdopsis genomes.

Our goal at MOsDB is to provide all available data about rice genes and genomics, including (in the future) mutant information and expression profiles. At this moment, the MOsDB database includes current (updated on daily basis) published sequences and gene annotation information of two Oryza sativa subspecies: japonica and indica.

Rice river

The O.s. spp. japonica (Nipponbare) sequence data is a result of international effort launched in 1997. The International Rice Genome Sequencing Project deploys a chromosome by chromosome, clone by clone approach, and deposits BAC/PAC-sized contigs to the public databases.

Monsanto and Syngenta, two US-operating companies, have also announced the establishment of working drafts of the rice genome at different coverage in April of 2000 and February of 2001, respectively.

Rice field

The genome sequence of O.s. spp indica was obtained by a "whole genome shotgun". The project was initiated in May, 2000 at Beijing Genomics Institute and the working draft was done in Oct. 2001. The release covers the draft sequence assembly of the rice genome from 93-11, a cultivar of domesticated rice subspecies (indica), the major rice subspecies cultivated in China and many other Asian-pacific regions. Functional coverage of the assembled sequence, based on STSs, ESTs, and full-length cDNAs, is estimated to be 92%.
