In this research project, the regulatory mechanisms of social organization in termites were extensively investigated, by focusing on signaling molecules such as hormones and pheromones. Endocrine factors were found to regulate the expression patterns of downstream developmental factors, leading to the development of caste-specific morphological characteristics. In addition, various exocrine glands were found to produce caste-specific pehromones, suggesting that the regulatory mechanisms of colonies based on chemical communications would exist in termites. Moreover, based on extensive transcriptomic analyses, the gene catalogs in three termite species were successfully constructed and it was revealed that there are some termite-specific features of gene repertoires. In future, further extensive analyses on the regulatory mechanism of genes underlying the elaborate social systems in termites.
