Large-Scale Phenomics Identifies Primary and Fine-Tuning Roles for CRKs in Responses Related to Oxidative Stress
The crk5 was insensitive to all studied stimuli, whereas crk31 was particularly insensitive to O3. The lines crk19-1 and crk22 were more sensitive to the analysed stimuli. (A) Scatter plot of stomatal responses of crk mutants to O3 (x-axis) and CO2 (y-axis). (B) Scatter plot of stomatal responses of crk mutants to O3 (x-axis) and darkness (y-axis) (C) Scatter plot of stomatal responses of crk mutants to CO2 (x-axis) and darkness (y-axis). Dashed lines indicate the cut-off for reduced, normal, and high response with respect to Col-0. Grey dashed lines show regression fit with correlation (R), coefficient of determination (R2) and significance reported in lower right corner in each plot. Reduced or increased responses were statistically significant in the majority of mutants (see respective barplots in S17, S18 and S19 Figs).
