Mechanisms of plant innate immunity

N. O. Kozyrovska

Plant innate immunity is assured by both constitutive and induced mechanisms. The constitutive barrier for pathogens relies on the plant cell wall structure, and the varieties of inducible systemic resistance result from interaction of the plant with pathogenic necrotrophic microorganisms, nonpathogenic bacteria, and also after the contact with some natural or synthetic substances. Description of both mechanisms of plant systemic resistance to pathogens and other stressors is the purpose of the review.

Key words: plant innate immunity, systemic acquired resistance, inducible systemic resistance.
