Fig. 8From: A pattern-triggered immunity-related phenolic, acetosyringone, boosts rapid inhibition of a diverse set of plant pathogenic bacteriaFluorescent microscopic images of P. syringae pv. tabaci bacteria treated with an AS mix, and stained to evaluate changes in membrane permeability and polarity. P. syringae pv. tabaci (105 CFU/ml) was treated with a mixture of AS + H2O2 + POX. After 3 h of shaking, (a) DIBAC4(3), an indicator dye of membrane depolarization or (b) SYTOX Green, an indicator of membrane permeability, and DAPI as counterstain were added and co-incubated for 1 h. After concentration of the bacteria, microscopic slides were prepared and photographed within 1–2 h. Bar = 100 μm.
