Entrez Genome (30) provides access to genomic sequences from the RefSeq collection and is a convenient portal both for retrieving such sequences from multiple organisms and for viewing small genomes, such as those from prokaryotes. Currently, the database contains complete genomes for >1000 microbes and 3400 viruses, as well as for over 2000 eukaryotic organelles. For higher eukaryotes, the Genome database includes genomes for 32 species, as well as data from almost 550 WGS projects for 80 species. More than 20% of the almost 11 000 total sequences were added in the past year. For higher eukaryotes, Entrez Genome provides direct links to the NCBI Map Viewer; for prokaryotes, viruses and eukaryotic organelles, specialized viewers and BLAST pages are available. The Plant Genomes Central web page serves as a portal to completed plant genomes, to information on plant genome sequencing projects or to other resources at NCBI such as the plant Genomic BLAST pages or Map Viewer.
