Plant immunity
An attempt to comprehend plant defense mechanism
Keywords:
plant immunity, microbial pattern, triggered immunity, phytoalexins, elicitors, effector triggered immunityAbstract
Immunity is a term closely affiliated with the normal being of an organism as it puts across a cascade of physiological facets that contributes affirmatively towards the knocking down of the invaded pathogen. It is a widely known and accepted fact that cells associated with the immune system serve as driving force in eliminating the disease causing agent and plants are not exempted from this mechanism but the approach of counteracting a pathogenic contender in plants are quite different from that of higher vertebrates. Several factors of internal and external origin have equally contributed towards the development of plant immunity. However, the role of microbes in conferring immunity to plants cannot be denied and their prominence in accordance with the fortifying the plant system against the invading pathogens have been extensively researched. Responses like systemic acquired resistance and induced systemic resistance have been studied in plants which get triggered in response to various micro invaders of pathogenic and non pathogenic echelon. Several studies claim the role of microbes in instigating either of these responses that in turn gives rise to a cascade of reactions within the plants resulting in plant immunity. T
