Overexpression of CaSLP confers enhanced resistance to Pst.DC3000 stress in transgenic Arabidopsis. A, D Phenotype of transgenic and WT plants after the Pst.DC3000 infection. Plants were infected with Pst.DC3000 for 3 days. B, E Histochemical staining with 3,3’-diaminobenzidine (DAB) and Trypan blue for measuring the H2O2 contents of the transgenic and WT plants after 3 d of Pst.DC3000 infection. Bar = 50 μm. C, F Trypan blue and DAB staining for cell death in the transgenic and wild-type (WT) plants after 3 d of Pst.DC3000 infection. G Bacterial numbers. H Chlorophyll contents in the transgenic and WT plants after 3 d of Pst.DC3000 infection. I-K The expressions of the SA response genes of AtNPR1, AtPAL3, and AtICS. Values are means ± SD (n = 3 replicates). Asterisks indicate a significant difference between the transgenic lines and WT under drought stress (*, P < 0.05; **, P < 0.01)
