Studies on The Expression of Isozyme Genes in Pupae and Embryogenesis of Antheraea pernyi

The expression models of the genes in several isozymes in pupae and embryogenesis of tussah,Antheraea pernyi were studied by means of polyacrylamide gel electrophoresis.The results showed the genes of MDH and SOD were expressed in hemolymph,lipid body,oocytes and embryogenesis,while the expression of the genes of LDH and EST appeared only in lipid tissue specificity.The choline esterase did not obviously express during the embryogenesis until larvae.The carboxylesterase,peroxidase and catalase,which dealt with the resistance to the insecticides,were not detected in pupae and embryogenesis.The reuslts of the studies offered an expression model of several isozyme genes in tussah.This also offered a good reference for the study on the resistance of pest insects.
