From: ABA-mediated regulation of leaf and root hydraulic conductance in tomato grown at elevated CO2 is associated with altered gene expression of aquaporins

Fig. 1: Leaf gas exchange and stomatal morphology response of the two tomato genotyes to different CO2 growth environments.

Net photosynthetic rate (An) (a), stomatal conductance (gs) (b), and stomatal density (SD) (c) of wild-type tomato “Ailsa Craig” (WT) and its respective ABA-deficient mutant (flacca) grown at ambient (400 ppm, a[CO2]) and elevated (800 ppm, e[CO2]) atmospheric CO2 concentrations. The effects of CO2 growth environment (CO2) and genotype (GE) as well as their interactions CO2 × GE are presented (two-way ANOVA). The different letters on the columns indicate statistically significant difference between the treatments by Tukey’s test at P < 0.05. Error bars indicate standard error of the means (SE) (n = 8)
