Cytoplasmic lipid droplet (LD) lipolysis is regulated by pheromone biosynthesis activating neuropeptide (PBAN) in Bombyx mori. To elucidate the molecular mechanism of cytoplasm LD lipolysis, the pancreatic lipase‐like gene in B. mori pheromone glands (PGs), designated as B. mori pancreatic lipase‐like gene (BmPLLG), was identified in this study. Spatial expression analysis revealed that BmPLLG is a ubiquitous gene present in all studied tissues, such as PGs, brain, epidermis, egg, midgut… Expand
Glycerol-3-phosphate O-acyltransferase is required for PBAN-induced sex pheromone biosynthesis in Bombyx mori
TLDR
Quantitative proteomics was utilized to comprehensively elucidate the expression dynamics of pheromone glands (PGs) during development and indicated that GPAT acts to regulate the biosynthesis of sex phersomone precursor, TAG, thus influencing PBAN-induced sex peromone production and subsequent mating behavior.
