| Outline of Final Research Achievements |
Morphologies of termite soldiers are specialized for colony defense. Developmental determination for soldiers is regulated by environmental factors during post-embryonic development. Juvenile hormone (JH) mediate this developmental processes. This study showed that Msh gene, which is expressed in wing disc of Drosophila melanogaster, plays a central role in soldier-specific morphological changes. Furthermore, this study showed that some wing developmental genes such as vestigial gene increased during presoldier development. These results suggest that the genes involved in wing formation plays a central role in termite soldier development.
