| Outline of Final Research Achievements |
In this study, we focus four mimicry systems in Lepidoptera, and clarified their responsible genes, regulation mechanisms, and evolutionary processes. Females of Papilio polytes mimics unpalatable butterfly P. aristolochiae. We found with linkage analysis and whole genome sequencing that this female-limited Batesian mimicry is caused by about 130kb autosomal region including doublesex, and that this region constitutes supergene structure and is produced and fixed by chromosomal inversion. In addition, we here revealed the responsible gene for larval pigmentation mutants of B. mori, pS and ms, respectively and that the Wnt signaling pathway regulates the larval spot pattern formation in Lepidoptera. We also clarified the molecular backgrounds underlying the larval pattern switch by juvenile hormone and the switch of pupal protective colors in response to larval environment in Papilio species.
