The induction speed of stomatal conductance and CO2 assimilation rate after step increase in light. The induction state of (A) stomatal conductance (gs) and (C) CO2 assimilation rate (A) were evaluated in the three lines of Arabidopsis based on gsinduction and Ainduction defined as Eqs. 1 and 2, respectively, under a PPFD of 500 μmol photon m–2 s–1 for 120 min after the dark period for 10 min. The time when (B) gsinduction and (D) Ainduction reached 5, 10, 20, 40, 60, and 80% (t5–80gs and t5–80A) of those maximum values was compared between WT and each transgenic line. (E) The steady-state value of gs under the dark condition (gsi) was compared between WT and each transgenic line. (F) The relationship was investigated between gsi and t60A. Vertical bars indicate the standard error (n = 3). *indicates significant differences in each parameter between WT and each transgenic line at p < 0.05, according to Dunnett’s test. The values in each column represent the relative value of each line to WT.
