Abstract: Bioinformatics is a cross subject between computer science and biology, the primary content of which contains biological database and biological information analysis. The development in nucleic acid database, protein database and the system of database integration were reviewed. Application of bioinformatics in some fields of rice research was introduced, such as exploiting new genes, comparative genomics and functional genomics. Its prospects are also discussed.

Key words: bioinformatics, database, comparative genomics, functional genomics, rice
