Light-induced stomatal opening in whole leaves. A, Mature leaves harvested from dark-adapted Col-0 plants (0 min) were illuminated with red light (RL), both red and blue light (RB), or kept in the dark (Dk) for 60, 120, or 180 min. Light intensities were 600 µmol m–2 s–1 for red light and 5 µmol m–2 s–1 for blue light. Data represent means of representative values from three independent measurements with sd. Asterisks denote statistically significant increases in the mean compared with that of 0 min (one-tailed Dunnett’s test: *, P < 0.05; **, P < 0.01; and ***, P < 0.001). Hash signs indicate that the mean of RB is statistically significantly higher than that of RL at each time point (one-tailed Student’s t test: #, P < 0.05). B, Light-induced stomatal opening in whole leaves from gl1 and phot1 phot2. Mature leaves harvested from dark-adapted plants were illuminated with red light (R60), both red and blue light (RB60), or kept in the dark (D60) for 60 min. Light intensities were the same as in A. Data represent means of representative values from four independent measurements with sd. Different letters indicate statistically significant differences among means (Tukey’s test: P < 0.05).
