Since the release of the whole genome sequence of Arabidopsis thaliana in 2000, we have determined the structures of the genomes of various model plants and crops which have a wide range of genome sizes and different ploidy using both Sanger sequencing and next-generation sequencing (NGS) technologies, and the obtained data have been released through public DNA databases and the individual genome databases from Kazusa DNA Research Institute (KDRI) (http://www.kazusa.or.jp/e/resources/database.html). The target plants include Solanum lycopersicum (tomato; estimated genome size: 900 Mb, polyploidy: diploid), Jatropha curcas (jatropha; 410 Mb, diploid), Eucalyptus camaldulensis (river red gum; 650 Mb, diploid), Solanum melongena (eggplant; 1.1 Gb, diploid), Raphanus sativus (radish; 530 Mb, diploid), Ipomoea trifida (wild sweetpotato; 520 Mb, diploid), and Fragaria × ananassa (strawberry; 800 Mb, octoploid). In addition, polymorphism analyses have been conducted for several crops, and the DNA markers developed for 13 plant species have been released from Kazusa Marker DataBase (http://marker.kazusa.or.jp). Recently, we generated a comprehensive genome database for plants, Plant Genome DataBase Japan (PGDBj; http://pgdbj.jp/?ln=en), which enables cross-searches on the following sub-databases: an orthologous database for plants and cyanobacteria (Ortholog DB), a plant resource database (Plant Resource DB), a DNA marker database for 80 plant species (DNA marker DB). In this presentation, the latest status of the above databases will be introduced.
