Abstract
Recently, large-scale 'omics data' from various plant species has been accumulated in public databases. For example, NCBI provides comprehensive omics data such as UNIGENEs, orthologous groups, gene expressions patterns as well as nucleotide sequences. In model plants, organism-specific databases have been also constructed and maintained, such as RAP-DB, MSU Rice Genome Annotation Project Database, OryzaExpress, SGN, MiBASE, KaFTom. These databases provide highly detailed information of genome annotations, ESTs, full-length cDNAs, DNA markers, Gene Ontology terms, gene expressions, metabolic pathways and so on. Integrated analysis of these large-scale omics data would allow us to understand complex biological systems. Here, we introduce the current status of omics databases and the integrated databases on rice and tomato.
