Outline of Final Research Achievements

Bombyx embryonic diapause is a unique process of seasonal polyphenism that is induced transgenerationally as a maternal effect in the bivoltine strain. Progeny diapause is determined by environmental factors such as light (photoperiod) and temperature during maternal embryogenesis. Both thermal and light (photoperiod) information was stored until the mid-pupal stage and was integrated with neuropeptide signaling to determine diapause phenotype, although the molecular mechanism(s) participating in light (photoperiod)-sensing and storage and integration of information remain unknown. In this study, we analyzed the light-sensing mechanism participating in diapause inducton.
