Abstract
Abstract Salicylic acid (SA) plays an important role in protecting plants from biotic stresses. Lelliottia amnigena is a newly identified potato soft rot pathogen and there are no adequate studies on this soft rot pathogen. Therefore, this paper focussed on the effect of SA on the mechanism under which L. amnigena causes potato soft rot. L. amnigena was examined and detected to secrete pectinase, proteases, pectin lyase and cellulase, which are the most important pathogenic enzymes involved in the production of plant diseases. Sterilised healthy potato tubers were inoculated with 0.2 mL of L. amnigena suspension (3.69 CFU · mL −1 × 10 7 CFU · mL −1 ). After 24 h, 200 μL of four different SA concentrations (0.5 mM, 1.0 mM, 1.5 mM and 2.0 mM) were used to treat the tubers. Co-culture of L. amnigena and SA significantly reduced the activity of pectinase, protease, pectin lyase and cellulase by an average of 33.8%, 43.4%, 67.7% and 46.9%, across the four concentrations (0.5 mM, 1.0 mM, 1.5 mM and 2.0 mM), respectively, compared to the control. The average disease index was reduced by 54.7% across the four SA concentrations. Treatment with SA induced transcriptional levels of the superoxide dismutase, peroxide, catalase and glutathione S-transferase across the four levels by an average of 3.87, 3.25, 3.97 and 3.94-fold, respectively, compared to control. Based on our results, we could state that SA could reduce the activities of these extracellular enzymes produced by L. amnigena by modulating both enzymatic and non-enzymatic antioxidant activities and gene expression that induce natural resistance in plants against bacterial infections.
