ElicitorsPlants in their natural habitat exposed to several pathogens, releasing various chemical substances to exhibit a cascade of interactions between the host and its pathogen (Figure1).An elicitor is a molecule that triggers defense response in the plant Abstract Plants, in their natural environment are encountered by numerous pathogens.However, plants have evolved with the innate immune system that can deal with attack of these pathogens.Nevertheless, pathogens also keep modifying themselves to counter the host immunity and thus making the plants susceptible.Over the years, several studies in various crop species on plant pathogen interactions, showed that understanding of host-pathogens is still an intriguing area of investigation.In this review, we s discuss the recent studies, which show the active role of pathogens and their effector proteins in bringing up the disease development in the host system.
