Changes in average stomatal widths induced by BdALMT12 overexpression or exogenous application of a calcium ionophore + malate

Values representing the averages from 100 stomata for each treatment are shown. Significance was determined by a lower-tailed Z test comparing each treatment against the opening control.

	WT stomata width	KD2 stomata width	Δ(WT–KD2)
	μm	μm
Young, untreated	1.52 ± 0.02	1.62 ± 0.02	−0.1 ± 0.005
Adult, untreated	1.55 ± 0.02	1.48 ± 0.02	0.06 ± 0.003	p < 0.001 (2 sample t test)
Adult, treated with malate and A23187	1.47 ± 0.02	1.32 ± 0.02	0.15 ± 0.004
Adult, Δ(untreated − treated)	0.08 ± 0.005	0.16 ± 0.005
	p < 0.001 (2 sample t test)
