Abstract
Rice is one of the most important food crops, and it is anticipated that genome-wide studies should contribute to finding agronomically-useful traits. The Rice Annotation Project (RAP) has provided highly accurate annotation of the complete rice genome sequence through the RAP-DB. Since the International Rice Genome Sequencing Project updated the genome assembly and several hundred thousands of paired end sequences obtained from full-length cDNAs were released, the annotation was thoroughly updated. The current version contains a wealth of novel information such as MPSS, microRNAs, transposons, and mutant information. For the user accessibility, the search systems for keywords and sequence homology was improved. How to use this database is demonstrated.
