摘要	The sesquiterpenoid methyl farnesoate (MF), a juvenile hormone (JH) analog, plays important roles in many physiological processes of crustaceans, such as morphogenesis, molting and reproduction. Juvenile hormone esterase-like (JHE-like) carboxylesterase (CXE) is a key enzyme in MF degradation, playing a significant role in regulating MF titer. However, its function is barely known in shrimp. In this study, a total of 21 JHE-like CXEs (LvCXEs) were characterized in Pacific white shrimpLitopenaeus vannamei, based on the full genome and multi-transcriptomic data.LvCXEhas a conserved triplet catalytic site (Ser-Glu-His) and a characteristic GxSxG motif. MostLvCXEs were highly expressed in the hepatopancreas, which was the main site for MF degradation.LvCXEs containing a GESAG motif showed a specific expansion in theL. vannameigenome. Those GESAG-containingLvCXEs presented differential expressions at different larvae stages and different molting stages ofL. vannamei, which suggested their potential functions in development and molting. Additionally, when the transcription level of CXEs was inhibited, it could lead to failed molt and death ofL. vannamei. When we further detected the expression levels of the key ecdysone responsive transcription factors includingLvE75,LvBr-C,LvHr3andLvFtz-f1after the CXE inhibitor was injected intoL. vannamei, they all showed apparent down-regulation. These results suggested that the expansion ofLvCXEs in theL. vannameigenome should contribute to the regulation of metamorphosis at larvae stages and frequent molting during the growth ofL. vannamei.
