The document discusses the Rice Annotation Project Database (RAP-DB), which provides annotation of the rice genome sequence. RAP-DB was created in 2004 after the rice genome was sequenced. Its main objective is comprehensive analysis of rice genome structure and function based on annotation. RAP-DB contains tools like BLAST, BLAT, and ID converter to allow users to search and analyze rice genes and genomes. It also contains GBrowse, which allows users to browse rice genes and view their precise locations and other details. Additional features include downloads, publications, links to other rice resources, and documentation.
