|Outline of Final Research Achievements
While many ecological and behavioral studies have been focused on the diversity of color vision and color pattern in dragonflies, its molecular bases have been poorly understood. We identified an extraordinary large number of visual opsin genes. These opsin genes are differentially expressed between adult and larva, as well as between dorsal and ventral regions of adult compound eyes. We also identified very long-chain methyl ketones and aldehydes as unique and major components of UV reflective dragonfly's wax. Moreover, we established an electroporation mediated RNA interference (RNAi) procedure in dragonflies.
