Loss of MPK3 or MPK6 suppresses the submergence-tolerant phenotypes of pldα1 and pldδ mutants. Phenotypes (A), survival rates (B), and dry weights (C) of WT, pldα1, pldδ, pldα1 mpk3 (α1 mpk3), pldα1 mpk6 (α1 mpk6), pldδ mpk3 (δ mpk3), and pldδ mpk6 (δ mpk6) plants upon submergence treatment. Four-week-old plants were photographed before submergence (air) and after 8 days submergence, followed by 3 days recovery (submergence). Survival rates and dry weights were calculated after recovery for 7 days. Bars, 1.5 cm. All experiments were performed on three biological replicates with similar results. Data in (B) and (C) are means ± sd of three biological replicates. Asterisks indicate significant differences from WT (*P < 0.05, **P < 0.01 by Student’s t test).
