“…The seminal vesicles are known to store, nourish, and maintain sperm before they are transferred into the female reproductive tract [26]. In addition, the seminal vesicles act as secretory organs that may assist in producing seminal fluid proteins in some insects [35][36][37][38][39][40]. However, how seminal vesicles impart these functions or whether there are additional functions is not understood.…”

Juvenile hormone (JH) is one of the most essential hormones controlling insect metamorphosis and physiology. While it is well known that JH affects many tissues throughout the insect life cycle, the difference in JH responsiveness and the repertoire of JH-inducible genes among different tissues has not been fully investigated. In this study, we monitored JH responsiveness in vivo using transgenicDrosophila melanogasterflies carrying aJH response element-GFP(JHRE-GFP) construct. Our data highlight the high responsiveness of the epithelial cells within the seminal vesicle, a component of the male reproductive tract, to JH. Specifically, we observe an elevation in the JHRE-GFP signal within the seminal vesicle epithelium upon JH analog administration, while suppression occurs upon knockdown of genes encoding the intracellular JH receptors,Methoprene-tolerantandgerm cell-expressed. Starting from published transcriptomic and proteomics datasets, we next identifiedLactate dehydrogenaseas a JH-response gene expressed in the seminal vesicle epithelium, suggesting insect seminal vesicles undergo metabolic regulation by JH. Together, this study sheds new light on biology of the insect reproductive regulatory system.
