MYC2 is required for regulation of reoxygenation-induced accumulation of AsA and GSH. Total AsA and GSH contents were measured in 4-week-old wild-type (WT), coi1-2, myc2-2, and MYC2-OE plants before submergence (Air) and after 24 h dark submergence (Sub) followed by 12 h reoxygenation (R12). Two biological replicates were conducted with similar results. The data are means ± sd (n = 5 technical replicates). Asterisks indicate significant differences from WT (*P < 0.05; **P < 0.01 by Student’s t test). “H” and “L” indicate significantly higher or lower contents, respectively, of AsA and GSH in the mutants or transgenic lines than in the WT.
