From: PMRD: a curated database for genes and mutants involved in plant male reproduction
Overview of the PMRD database architecture. Plant Male Reproduction Database (PMRD) is a comprehensive resource for browsing and retrieving knowledge about genes and mutants related to plant male reproduction. PMRD brings together three main sources of knowledge: (1) general genomic information from public databases; (2) detailed curation of genetic studies from the literature; (3) public annotation from the research community. Curated information and genomic information are stored in relational database tables that are accessed by a number of online utilities.
