Serpin7 controls egg diapause of migratory locust (Locusta migratoria) by regulating polyphenol oxidase.

ABSTRACT: Diapause is a state of arrested growth, which allows insects to adapt to diverse environments. Serine protease inhibitors (serpins) play an important role in various physiological processes, including blood coagulation, fibrinolysis, development, complement activation and extracellular matrix remodeling. We hypothesized that serpin may affect energy metabolism and thereby control diapause of migratory locust (Locusta migratoria) embryos by regulating protease cascades. A total of seven nonredundant serpin genes (named serpin1-serpin7) of L. migratoria were obtained through transcriptomic analysis. We further performed label-free proteomic sequencing and analysis of diapause and nondiapause eggs of L. migratoria, revealing significant differences in serpin7 expression. A significant reducti
