FIGURE 7

Expression of (A) ABA-responsive genes and (B) key regulator genes for thermotolerance in CaWAKL20-overexpressing Arabidopsis lines after heat stress treatment. RT, room temperature; HS, heat stress induction at 45°C for 3 h. AtActin2 was used to normalize gene expression, and the expression level under 0 h after treatment was taken as 1.0. Error bars represent standard deviations for three replicates, and each replicateconsisted of 12 seedlings. ** indicates significant difference at the 0.01 level.
