phyB mutants have enhanced cold tolerance. (A) Representative photographs of wild-type (WT) and phyB mutants (phyB1 and phyB2) under cold stress. Seedlings at the three-leaf stage were treated with cold (4°C) for 4 days and then allowed to recover at 28°C for an additional 7 days. (B) Survival rate of seedlings. (C) Electrolyte leakage index. (D) MDA concentration. Asterisk () indicates that the mean value is significantly different from that of the control: P < 0.05; ∗∗P < 0.01.
