Defense Induced by Jasmonic Acid: A Review

Plants are very delicate have no opportunity other than to adapt their growth and changing with environment and need to coordinate their growth and physiology responses. Plants present in an environment in ancient time characterized by the presence of various types of stresses both biotic and abiotic. Phytohormones play important role in plant growth, development and response to stresses. Plant hormones regulate diverse developmental processes and send the signals networks in plants under different abiotic stresses. With the advancement in plant biology research it has been established that phytohormones have the potential to remove the deleterious effects posed by abiotic stresses (Masood et al., 2012; Khan et al., 2013). Plant defense responses are mediated by three major pathways of the phytohormones, jasmonic acid (JA), salicylic acid (SA) and ethylene (ET). The fine tuning of plant response to pathogen depends on the synergistic or antagonistic interactions between these three pathways (Takahashi et al., 2004).
