Figure 4

The kinase inhibitor TP9 either abolished the BL-induced Kleaf increase or prevented the BL-induced stomatal opening, depending on the treatment route. Fully expanded leaves of WT (Col-gl) were preincubated (petiole deep) in AXS without or with TP9 (10 μM) or sprayed with AXS with or without TP9 (10 μM) and kept overnight in dark boxes. Immediately after the dark treatment, leaves were illuminated for 15 min with RL or RL + BL, as indicated. A, Kleaf. B, Stomatal conductance (gs). Other details are as in Figure 1. Note that Kleaf was reduced when TP9 was fed via the petiole, but not when it was sprayed on the plants, and that the opposite was true for gs.
