Outline of Final Research Achievements

Juvenile hormone (JH) represses precocious metamorphosis of larval to adult transitions. Ecdysone-induced protein 93F (E93) functions as an adult specifier gene in the pupal-adult transition. JH is known to repress E93 expression to prevent immature larvae from bypassing the pupal stage and progressing to precocious adult development; however, the molecular mechanism underlying JH-mediated E93 repression remains unknown. Here, I identified a cis- and tran-element concerning the repression, and demonstrated molecular mechanism underlying juvenile hormone-mediated repression of precocious larval-adult metamorphosis.
