Stomatal aperture modulation in lettuce treated with S. Typhimurium co-inoculated with salicylic acid (SA) (A) or abscisic acid (ABA) (B). Aperture changes at 0 h remains unchanged, and 0 h represents only the water control. Different letters signify a difference at p < 0.05. For each time point the average was found from three plants with n = 40–60 stomata imaged per plant.
