HL-induced protection of Cat1AS plants against Pseudomonas syringae pv. syringae. Cat1AS and control plants were either maintained at LL or exposed to HL for different times as described in the legend of Fig. 5 and returned to LL for 2 weeks. Leaf damage was assessed as described in Fig. 5. Then, Pseudomonas syringae pv. syringae at 106 per ml were inoculated by infiltration in the leaf and bacterial growth was determined after 24 h by plating serial dilutions of homogenate from inoculated tissue on solid medium (22). cfu, colony-forming units. The figure displays a representative result of three repetitions.
