The analysis of antioxidant enzymes in wild type and <i>pqt3</i> mutant.

<p><b>(A-J)</b> Quantitative RT-PCR analysis of transcript levels of antioxidant enzyme genes. RNA samples were isolated from 7-day-old wild type and <i>pqt3</i> seedlings for quantitative RT-PCR analysis. The transcript levels of APX <b>(A)</b>, GPX <b>(B)</b>, ACHT <b>(C)</b>, FSD <b>(D)</b>, CAT <b>(E)</b>, GRXC <b>(F)</b>, CSD <b>(G)</b>, PRXQ <b>(H)</b>, 2CPB <b>(I)</b> and MSD <b>(J)</b> were analyzed. Values are mean ± SD (n = 3 experiments, ***P < 0.001). Asterisks indicate Student’s t-test significant differences. <b>(K and L)</b> Enzyme activity of APX <b>(K)</b> and GPX <b>(L)</b> in wild type and <i>pqt3</i> mutant. The <i>pqt3</i> mutant has higher enzyme activity of APX and GPX than wild type. Values are mean ± SD (n = 3 experiments, ***P < 0.001). Asterisks indicate Student’s t-test significant differences.
