| Outline of Final Research Achievements |
In insects, sex-specific alternative splicing plays central roles on sex determination. As an initial step to understand the evolution of insect-specific sex determination mechanisms, we focused on the sex determination gene doublesex (dsx).
In this study, we successfully cloned dsx from two hemimetabolous insects such as the ferocious water bug, Appasus japonicas and the two-spotted cricket, Gryllus bimaculatus, and the ametabolous insect, Thermobia domestica. Interestingly, the dsx of T. domestica showed a novel expression pattern between males and females.
