| Outline of Final Research Achievements |
In this study, to identify genes involved in social organization in termites, comprehensive gene expression and evolutionary analyses were conducted in the Japanese damp wood termite Hodotermopsis sjostedti. First, the sequences of expressed genes obtained from soldiers, kings, queens, male neotenics, and female neotenics were determined with a next generation sequencer, and expression levels of the genes were estimated. As a result, 492 genes exhibited significantly higher expression levels in soldiers than in the other castes. Next, a comparative analysis was performed to detect positive selection in the ancestral lineage of termites, and found four genes that were positively selected. The differentially expressed genes and the positively selected genes are considered to be important in social organization in termites.
