PLC1 and GPA1 were involved in the CAG-induced stomatal movement. a and d Relative expression level of PLC1 and GPA1 under the CAG treatment in WT. b and e Activities of PLC and GTP hydrolysis under the CAG treatment in WT. c Stomatal apertures of A. thaliana leaves under the CAG treatment in WT, plc1, PLC1-CO, PLC1-OE. f Stomatal apertures of A. thaliana leaves under the CAG treatment in WT, plc1, gpa1, plc1/gpa1. g and h GPA1 and PLC1 relative expression under the CAG. Uppercase letters indicate differences between groups, lowercase letters indicate differences within groups. Means with different letters are significantly different at P < 0.05
