Figure 8. AHA1 constitutively active mutant lines are insensitive to PTI-mediated stomatal closure.

Figure 8

Stomatal apertures were measured in epidermal peels of wild-type Col 0 and Ler, as well as the AHA1 mutants ost2-2D and ost2-1D after incubation with water or 1×108 CFU/ml Pst DC3000 for 1 h (A) and 3 h (B). (C) Arabidopsis epidermal peels were floated on MES buffer containing the flagellin peptide Flg22 (5 µmol/l) and LPS 100 ng/µl). Stomatal apertures were measured after 3h. MES served as a control.
