Outline of Final Research Achievements

In termites, many individuals coopelatively form a society. The society involves division of labor among individuals, where some individuals (queens and kings) devoted to breeding, and the other individuals (workers etc.) do not reproduce and exhibit altruistic behavior such as feeding to other individuals. In this study, in order to identify genes involved in the division of termites, especially those related to development of workers (social genes), mating experiments and analyses using whole genome information were carried out. As a result, the candidates of the genomic regions for the social genes.

Academic Significance and Societal Importance of the Research Achievements

社会性の進化は、単細胞生物から多細胞生物細菌への進化と並ぶ、生物進化の大イベントであり、生物進化について理解を深めるために探究すべき重要な現象である。本研究では、特に複雑で巨大な社会を構築するシロアリにおいて、その社会性がどのような遺伝子によって生み出されるのかを解明することを目的とした。本研究の結果、シロアリの社会性に関わる遺伝子の候補を選定することができた。今後、それらの遺伝子の機能解析を行うことで、社会性を生み出す分子機構の解明につながる。
