(a) Semi-quantitative RT-PCR analysis of CYP4G19 mRNA expression levels. A, Gel electrophoresis analysis of PCR products of actin and CYP4G19 genes. Lane 1~6: Pesticide sensitive strain; Lane 1~6: Wild strain. (b) Bar chart of semiquantitative RT-PCR analysis. The white bars were wild strain and the black bars were sensitive group. Asterisks indicated differences statistically significant P<.01 (t-test). Data of (b) represent means OD values ± SEM of three independent experiments, and each experiments including five samples of wild and sensitive strains.
