PLC1 and GPA1 located upstream of NO to regulate CAG-induced stomatal movement. a After 10 μM NO donor SNP was applied, stomatal apertures of A. thaliana leaves under the CAG treatment in WT, plc1, gpa1, and plc1/gpa1. b Relative expression level of PLC1 under the CAG treatment in WT, nia1, noa1. c Relative expression level of NIA1 under the CAG treatment in WT, plc1, gpa1, plc1/gpa1. d Relative expression level of NOA1 under the CAG treatment in WT, plc1, gpa1, plc1/gpa1. Uppercase letters indicate differences between groups, lowercase letters indicate differences within groups. Means with different letters are significantly different at P < 0.05
