The Rice Annotation Project (RAP) was conceptualized in 2004 upon the completion of the Oryza sativa ssp.  japonica cv.  Nipponbare genome sequencing by the International Rice Genome Sequencing Project  with the aim of providing the scientific community with an accurate and timely annotation of the rice genome sequence. One of the major objectives of this project is to facilitate a comprehensive analysis of the genome structure and function of rice on the basis of the annotation.
Here we provide our updated annotation using the Os-Nipponbare-Reference-IRGSP-1.0 (IRGSP-1.0), a new genome assembly constructed  as a joint collaboration of RAP and the MSU Rice Genome Annotation Project. The IRGSP sequences were re-examined using ~44X coverage sequence reads obtained by next-generation sequencers, so that many sequencing errors have been thoroughly corrected. In the present era of massive genome sequencing, the high-quality reference sequence of the rice genome will be more valuable to meet the demands of biodiversity studies and to enhance our understanding of major cereal crops.
