FIGURE 5.

Expression of ROS-scavenging genes in response to ABA treatment. Total RNA was isolated from 10-d-old seedlings of WT and ars1 mutants with or without ABA (100 μM) treatment for 3 h. Relative transcript levels of CCS (A), CSD3 (B), APX1 (C), and APX2 (D) in Col-0 and ars1 mutants determined by qRT-PCR. Transcript levels were normalized to those of TUBULIN2. Bars represent mean ± SD of three biological replicates with three technical replicates each. Asterisks represent significant differences from the Col-0 (^∗; 0.01 < p-value ≤ 0.05, ^∗∗; p-value ≤ 0.01, Student’s t-test).
