Effect of ALA on stomatal density and size of Arabidopsis.

Plant	Stomatal density (number mm^-2)	Stomatal length (μm)	Stomatal width (μm)
WT	288 ± 14^a	20.91 ± 0.26^a	17.55 ± 0.26^a
P₀	268 ± 19^a	21.56 ± 0.24^a	18.09 ± 0.24^a
P₃	305 ± 12^a	21.35 ± 0.20^a	18.47 ± 0.20^a

WT, wild-type; P₀ and P₃, two ALA-over-producing transgenic lines. Values are the means of 90 measurements ± SE from three independent experiments. The same letters within the same column indicate no significant difference at P = 0.05 level.
