Fig. 2

The involvement of AtMPC1 in stomatal movement and drought response. a The transcript level of AtMPC1 was identified by qPCR in the mpc1 mutant, the overexpressing line OE-1, and the complementation line C-1. b ABA-induced stomatal closure according to a width/length ratio analysis of stomatal aperture. Values are means ± SE (n = 3). Before width/length ratio analysis, at least 30 stomata were measured. *: significantly different at P < 0.05. c Representative stomata from plants untreated or exposed to 50 μM ABA. Bar: 10 μm. d The rate of water loss from the detached leaves of various transgenic lines. e The effect of withholding water from soil-grown Col-0, mpc1, OE-1, and C-1 plants
