Syntaxin is one of the plants housekeeping resistance protein, occurred in most of the plants. Plants resist microbial attack using elaborate nonself surveillance systems consisting of a repertoire of cell surface and intracellular immune sensors. Thus plants must have evolved defense mechanisms to terminate extracellular colonization attempts. The plant must, therefore, promote an active resistance mechanism to combat the extracellular infection. Resistance against bacteria is manifested and whether similar processes mediate basal, gene for-gene, and salicylate-associated defense, however, so many resistant proteins are poorly understood. The influence of plasma membrane syntaxin is a component contributing to gene-for-gene resistance in Nicotiana benthamiana. Silencing the apparent orthologue of a syntaxin required for resistance to powdery mildew fungus, compromised resistance because syntaxins may play a role in secretion of proteins to the extracellular space, proteomic analysis of the apoplastic fluid. Syntaxin silenced plants were impaired in the accumulation of at least a subset of pathogenesisrelated (PR) proteins in the cell wall. SYP132-dependent secretion is a component of multiple forms of defense against bacterial pathogens in plants. Thus, we are implementing the Phylogenetics or comparative approach towards the syntaxin sequences observed in multiple plant genomes.
