Modulation of maximal stomatal aperture by altered guard cell arabinans leads to altered gas exchange

(A–D) Stomatal conductance (A and B) and assimilation rate (C and D) in leaves under a range of CO₂ concentrations (as indicated) for arad1 (A and C) and ARAD1-OE (B and D) relative to controls.

(E–H) Stomatal conductance (E and F) and assimilation rate (G and H) in leaves under a range of irradiance levels (as indicated) for arad1 (E and G) and ARAD1-OE (F and H) relative to controls. n = 5 independent plants, with error bars = SEM.
