| Outline of Final Research Achievements |
Juvenile hormone (JH) is known to repress pupal metamorphosis in insects. However, the molecular mechanism underlying the JH-mediated repression of pupation has remained unclear. In this study, I focused on a pupal specifier gene and analyzed the molecular mechanism. As a result, JH-inducible protein (Kruppel homolog 1) directly represses transcription of pupal specifier gene and thereby represses insect pupation.
