Juvenile Hormone Epoxide Hydrolase: a Promising Target for Hemipteran Pest Management
Abstract Juvenile hormone epoxide hydrolase (JHEH) has attracted great interest because of its critical role in the regulation of juvenile hormone (JH) in insects. In this study, one JHEH gene from Apolygus lucorum (AlucJHEH) was characterized in terms of deduced amino acid sequence, phylogeny, homo...

| Sumario: | Abstract Juvenile hormone epoxide hydrolase (JHEH) has attracted great interest because of its critical role in the regulation of juvenile hormone (JH) in insects. In this study, one JHEH gene from Apolygus lucorum (AlucJHEH) was characterized in terms of deduced amino acid sequence, phylogeny, homology modeling and docking simulation. The results reveals a conserved catalytic mechanism of AlucJHEH toward JH. Our study also demonstrates that the mRNA of AlucJHEH gene was detectable in head, thorax and abdomen from all life stages. To functionally characterize the AlucJHEH gene, three fragments of double-stranded RNAs (dsRNAs) were designed to target different regions of the sequence. Injection of 3rd nymphs with dsRNA fragments successfully knocked down the target gene expression, and a significantly decreased survival rate was observed, together with a molting block, These findings confirm the important regulatory roles of AlucJHEH in A. lucorum and indicate this gene as a promising target for future hemipterans pest control. |
