Abstract
Here we present a brief review of the reports concerning proteome modifications under the influence of salicylic acid, which is one of the major mediators of both local and systemic immunity. We describe also the results of our own studies of the salicylate-induced changes in proteomes of pea leaves and roots. Fifteen salicylate-inducible proteins, which were previously unknown, have been identified. Unlike the roots, leaves accumulated some chloroplast proteins and enzymes capable of degrading the pathogen cell walls. In the roots, salicylic acid increased the content of enzymes, improving the resistance of plant cells themselves, and promoted the disappearance of reductase of oxophytodienic acid. The latter could lead to inhibition of jasmonic acid synthesis and stimulation of local immunity. High (apoptotic) concentration of salicylic acid intensified synthesis of root proteins involved in the formation of heteroprotein complexes, which play an important role in the functioning of the signaling system, DNA synthesis and repair, and protein synthesis, refolding, and proteolysis.
