Proteomic Analysis of MeJa-Induced Defense Responses in Rice against Wounding.

摘要: The role of jasmonates in defense priming has been widely recognized. Priming is a physiological process by which plant exposed to low doses biotic or abiotic elicitors activates faster and/or stronger responses when subsequently challenged stress. In this work, we investigated the impact MeJA-induced mechanical wounding rice (Oryza sativa). proteome reprogramming plants treated with MeJA, MeJA+wounding in-depth analyzed using combination high throughput profiling techniques and bioinformatics tools. Gene Ontology analysis identified protein classes as defense/immunity proteins, hydrolases oxidoreductases differentially enriched three treatments, although different amplitude. Remarkably, proteins involved photosynthesis oxidative stress were significantly affected upon MeJA-primed plants. Although these had previously shown play responses, our study revealed that they are specifically associated MeJA-priming. Additionally, also showed at phenotypic level MeJA protects from photosynthetic damage induced wounding. Taken together, results add novel insight into molecular actors mechanisms orchestrated enhancing defenses after
