Changes in gas exchange parameters as influenced by COMT1 silencing and heat stress in tomato leaves. (A) The light-saturated rate of CO2 assimilation (Asat), (B) stomatal conductance (Gs), (C) intercellular CO2 concentration (Ci), and (D) transpiration rate (Tr). Tomato seedlings at five-leaf stage were exposed to 40°C temperature for 9 h before analysis of gas exchange parameters. Data are presented as the mean of six replicates (±SE). Different letters indicate significant differences (P < 0.05) according to the Tukey’s test.
