The Plant Resistance Genes (PRG) database is intended to serve as a research tool to identify and study genes involved in the disease resistance process in all plants. Data from a variety of on-line resources and literature are stored in several sections to create a unified knowledge resource with emphasis on R gene characterization and classification. The database was designed so as to allow easy integration with other data types and existing and future databases. For each cloned R gene (reference gene) is provided a fine locus annotation, reporting also homologous sequences and related disease sequences. Moreover we built cross links with pathogen and disease information to obtain a complete view of the plant-gene-pathogen interaction system.
