| Outline of Final Research Achievements |
In this research project, focusing on sexual dimorphism and phenotypic plasticity (polypheniesm), a number of researches on the phenotypic regulations were carried out, and as the results, many insights and new findings were obtained through the studies using termites, aphids and stag beetles. In the termite caste differentiation, the juvenile hormone action is strongly involved in the sexually biased caste differentiation pathways. In aphids, mechanisms of sex determination and of gamate formation were revealed. In stag beetles, transcriptomic analyses revealed a series of sex-determination factors, on some of which functional assays were carried out.
