  Salicylic Acid (SA) plays an important role as an endogenous signal in mediating plant defense responses against pathogens. This study investigated the effects of SA on biofilm formation by Xanthomonas oryzae pv. oryzae (Xoo) and its ability to induce systemic resistance in rice against Bacterial Leaf Blight (BLB). Results demonstrated that treating rice plants with 0.5 mM SA significantly suppressed the growth and biofilm formation of Xoo. Transmission Electron Microscopy (TEM) confirmed that SA treatment caused noticeable changes in bacterial cell morphology, including swelling and wall alterations. In greenhouse experiments, SA inhibited the pathogen by 50.45% and increased plant height, fresh weight, and dry weight in treated rice plants. Additionally, SA application enhanced the activity of defense-related enzymes such as Polyphenol Oxidase (PPO), Peroxidase (POD), Phenyl Ammonia.. View more»
