The goal of this study was to investigate the role of lipopolysaccharides (LPS) in induction of resistance in tomato against the causal agent of bacterial spot, Xanthomonas perforans . The results showed that pre-treatment with LPS leads to enhancing resistance of tomato against X. perforans . In addition, expression profiling of β-1,3-glucanase (BGL), Phenylalanine ammonia-lyase (PAL) and catalase (CAT) was examined during the induced resistance by LPS. The effect of LPS on induction of BGL , PAL and CAT was demonstrated in the present study. The data suggest that the effect of LPS on resistance of tomato against X. perforans could be through activation of some defence genes such as of BGL , PAL and CAT which afford defence responses against the pathogen. Our findings might help to better understanding the molecular bases of the induced resistance by LPS.
