Abstract
The aim of Oryzabase is to create a comprehensive view of rice (Oryza sativa) as a model monocot plant by integrating biological data with molecular genomic information (http://www.shigen.nig.ac.jp/rice/oryzabase/top/top.jsp). The database contains information about rice development and anatomy, rice mutants, and genetic resources, especially for wild varieties of rice. The anatomical description of rice development is unique and is the first known representation for rice. Developmental and anatomical descriptions include in situ gene expression data serving as stage and tissue markers. The systematic presentation of a large number of rice mutant and mutant trait genes is indispensable, as is description of research in wild strains, core collections, and their detailed characterization. Several genetic, physical, and expression maps with full genome and cDNA sequences are also combined with biological data in Oryzabase. These datasets, when pooled together, could provide a useful tool for gaining greater knowledge about the life cycle of rice, the relationship between phenotype and gene function, and rice genetic diversity. For exchanging community information, Oryzabase publishes the Rice Genetics Newsletter organized by the Rice Genetics Cooperative and provides a mailing service, rice-e-net/rice-net.
