Elicitors defence response in plants against pathogen infection
Author(s): Vivek Chandra Verma
Abstract: Plants can activate elicitors molecules for defence pathway depending upon the pathogen encountered. Originally the term elicitors are used for molecules capable of inducing the production of phytoalexin or the compound stimulating any type of plant defence. Elicitors can be classified on the basis of origin, nature and defence response. The primary immune response of plant defence involves the recognition of pathogen (or microbe) associated-molecular patterns (PAMPs/MAMPs). PAMPs are recognized by specialized trans membrane proteins in the plant, termed pattern recognition receptors (PPRs). PPR can be suppressed by AVR factor which recognized by the host encoded resistance (R) proteins confer ETI (Effector triggered immunity). ETI generally associated with HR and SAR. Nitric oxide biosynthesis in plants can be achieved by two pathways: oxidative pathway and reductive pathway. Nitric oxide plays an important role in the recognition of neurotropic pathogens as well as great impact on SA and JA biosynthesis. Salicylic acid (SA) is a small phenolic compound that regulates plant resistance against bio trophic pathogen.
