| Outline of Final Research Achievements |
Dragonflies recognize their mates primarily by vision, and thus there is striking diversity in the coloration and markings between sexes and among closely related species. Although the molecular basis underlying color formation in dragonflies has been largely unknown, this study described the morphological changes during nymph-to-adult metamorphosis in various dragonfly species and found that local RNAi in the first half of the final instar nymphs can inhibit gene function with almost 100% efficiency, at least for epidermis. Using this method, we succeeded in identifying the three transcription factor genes that are essential for metamorphosis into adults and several genes that are important for color formation.
