Construction of 5 transgenic Drosophila strains with 5 CYP genes from Laodelphax striatellus and Q-PCR verification
Abstract：Constructed transgenic vectors of pUAST-attB-CYP6CS2v1, pUAST-attB-CYP6BD10v2, pUAST-attB-CYP439A1v3, pUAST-attB-CYP6FJ1v2 and pUAST-attB-CYP4C72, were introduced into Drosophila embryos respectively, by microinjection. Homozygous transgenic Drosophila strains of UAS-CYP6CS2v1, UAS-CYP6BD10v2, UAS-CYP439A1v3, UAS-CYP6FJ1v2 and UAS-CYP4C72 were obtained by screening and purification. The tub-gal4 Drosophila melanogaster strain with β-tubulin promoter was genetic crossed with UAS-CYP6CS2v1, UAS-CYP6BD10v2, UAS-CYP439A1v3, UAS-CYP6FJ1v2 and UAS-CYP4C72 respectively to obtain the systemic overexpression strains of tub>CYP6CS2v1, tub>CYP439A1v3, tub>CYP6FJ1v2, tub>CYP4C72 and tub>CYP6BD10v2. By using the real-time quantitative PCR method, the expression levels of target genes in the experimental groups were detected. The results showed that the expression levels of CYP6CS2v1, CYP6BD10v2, CYP439A1v3，CYP6FJ1v2 and CYP4C72 in the experimental groups were 9.95, 30.39, 19.10, 33.30 and 38.42 times than that in control groups. The expression levels of endogenous related CYP genes in Drosophila were significantly lower than the expression level of target genes. At the same time, there was no significant difference (P > 0.05). Therefore, the CYP6CS2v1, CYP6BD10v2, CYP439A1v3, CYP6FJ1v2 and CYP4C72 genes of small brown planthopper were overexpressed in the Drosophila.
