The article conveys some information:
Me salicylate (MeSA) is a volatile biol. compound synthesized from salicylic acid (SA) and is a plant hormone that helps defend against pests and pathogens. A major bacterial pathogen of rice, Xanthomonas oryzae pv. oryzae (Xoo) causes severe disease. Seed and plant treatments with MeSA can stimulate the defense enzyme peroxidase (POD) in plants. Response of peroxidase activity in rice (Oryza sativa L) cultivars IR 20, IR 50, IR 64, ASD 16, ASD 19 and ADT 46 to MeSA were measured under greenhouse conditions. Treatments of rice seedlings with MeSA at 50 and 100 mg L-1 significantly upregulated POD expression in the plants. The activity of POD was also significantly upregulated when plants were inoculated with bacterial blight. Effects were stronger in ASD 16, ASD 19 and ADT 46 and were more pronounced in high dose treatment (100 mg L-1) when inoculated with bacterial blight condition and the effects were dose dependent, although the relationship between dose and rice varieties were not always linear. The pathogenic related (PR) protein bands at 33 kDa and 14 kDa were identified in treatments of 100 mg L-1 MeSA in the presence of bacterial blight disease. Band intensity was estimated to be twice that of those from pathogen induce MeSA levels in rice plants. These results suggest that treatment with MeSA can significantly increase the POD defense related enzyme by altering the plant physiol. in ways that may be beneficial for crop protection. The results came from multiple reactions, including the reaction of Methyl Salicylate(cas: 119-36-8Quality Control of Methyl Salicylate)
Methyl Salicylate(cas: 119-36-8) is a natural herbivore-induced plant volatile. It is a naturally occurring product in trees, legumes, exotic plants, vegetables, berries, and the primary constituent of the oil of wintergreen.Methyl Salicylate is produced from salicylic acid.Quality Control of Methyl Salicylate
