Figure 1.

The mean change in foliar ABA level (n = 3, ±95% confidence interval) in two herbaceous angiosperm species (P. sativum wild type [A] and wilty [B]; Arabidopsis [C]) after excised leaves were exposed to external pressures for 20 min (black circles) or 60 min (white circles). Vertical lines indicate Ψtlp (Supplemental Fig. S3). The insert in A depicts the mean change in foliar ABA level (n = 4, ±95% confidence interval) in leaves of P. sativum with the abaxial epidermis removed after floating on aqueous solutions of PEG 4000 mixed to particular water potentials for 20 min (black circles) or 60 min (white circles). Stars denote a significant change in foliar ABA level (n.s., not significant; * P < 0.05; ** P < 0.01; *** P < 0.001). Foliar ABA levels presented in terms of dry weight are shown in Supplemental Figure S4.
