Involvement of Taiman in juvenile hormone signaling controlling sexual maturation in a male moth.

ABSTRACT: In insects, juvenile hormone (JH) is essential for orchestrating reproductive events. For example, in the male moth Agrotis ipsilon, the behavioral response to female sex pheromone is linked to neuronal sensitivity in the primary olfactory centers (antennal lobes, ALs), and the maturation of accessory sex glands (ASGs) are known to be age- and JH-dependent. The molecular basis of this regulatory action of JH is not fully deciphered, and we show here that the heterodimerizing partner of Methoprene-tolerant called Taiman (Tai) is essential for the sexual maturation of male A. ipsilon. Tai expression in ALs and ASGs is elevated from the third day of adult life and is responsible for the acquisition of behavioral responsiveness to the sex pheromone and ASG maturation. Tai-
