<p>A and B, Stomatal aperture and conductance in <i>V. faba</i> leaves dip-inoculated with mock or DH5α at 10<sup>8</sup> CFU/ml under light/dark transition; C and D, Stomatal aperture and conductance in <i>V. faba</i> leaves dip-inoculated with mock or DH5α at 10<sup>8</sup> CFU/ml under different field water content (FWC). Data from the epidermal bioassay are means of 120 stomatal aperture measurements from three replicates ±SEM. Data from the stomatal conductance experiment are means of measurements from 8–12 leaves (n = 4). Asterisks denote significant differences as analyzed by two-tailed <i>t</i>-test (***, <i>P</i><0.001; *, <i>P</i><0.05; ns, no statistical difference).</p
