- Abstract
<italic>Xanthomonas perforans</italic> is the causal agent of bacterial spot, one of the most devastating diseases of tomato that results in considerable yield losses worldwide. Rutin, as a polyphenolic substance, was used to induce resistance in tomato against <italic>X. perforans</italic>. Rutin at concentration of 2 mM had ability to reduce the disease severity of bacterial spot. On the other hand, 2 mM rutin had no antibacterial activity in vitro. Expression profiling of pathogenesis-related gene 5 (<italic>PR-5</italic>), Phenylalanine ammonia-lyase (<italic>PAL</italic>) and lipoxygenase (<italic>LOX</italic>) was probed during the enhanced resistance by rutin. Pretreatment with rutin (rutin/ <italic>X. perforans</italic>) led to induction of <italic>PR-5</italic>, <italic>PAL</italic> and <italic>LOX</italic> compared to controls (water/ <italic>X. perforans</italic>). Our results suggest that rutin-induced resistance against <italic>X. perforans</italic> in tomato might be mediated through stimulation of some defense genes such as <italic>PR-5</italic>, <italic>PAL</italic> and <italic>LOX</italic>.
