Genome sequencing of crop pests and development of integrated databases for broad agricultural pests

 Agricultural pest control technology is one of the most important keys for the stable supply of agricultural products. In Insect Genome Research Unit, we are targeting research that will lead to environmentally friendly and efficient insect pest control methods. For this purpose, we are conducting the following research. Using silkworm as the model organism for other Lepidopteran agricultural pests, we sequenced the silkworm genome and acquired gene expression information. The accumulated data are stored in the integrated silkworm genome database, KAIKObase, which is available world-wide. Based on the silkworm genome information, we are investigating the genes in diamondback moth, the major cruciferous vegetable pest to control pests in the Brassica family. We are also analyzing the genome of the brown planthopper, one of the major rice pests, and investigating the genes related to pesticide resistance which will contribute to development of new pesticides that show low or minimum resistance.
 We also construct a crop pest database that accumulates a great deal of crop pest genome information and has a user friendly interface. Using the system, one can access integrated insect genome data sets with high-speed processing.
