Putative signaling pathways in H.virescens ovarial patency

Patency is a process caused by juvenile hormone (JH) in follicle epithelium cells. JH stimulates shrinking of these cells, thereby enabling sequestration of nutritive proteins by the oocyte, and- later- development of the embryo. Using Heliothis virescens as a model, we propose signaling pathways that juvenile hormone homologues use in the egg development, and suggest the nature of putative juvenile hormone membrane receptor.
