The cytochrome P450-dependent monooxygenases paly an extremely important role in metabolic system involved in the catabolism and anabolism of xenobiotics and endogenous compounds.Cytochrome P450 is a key constituent which acts as the terminal oxidase in monooxygenase systems to oxidize diverse substrates.Insecticide resistance has been proven to be correlated with monooxygenase-mediated metabolism.According to the predicted P450 sequences from the genome of Bombyx mori,a pair of primers were designed and a ...
