Defence mechanisms

Microbial Pathogenesis

Plants under natural environment facing various pathogens, tend to produce defense to maintain their fitness and minimize pathogenic damage. Plant-pathogens interaction is gaining more importance by researches as, their means of the fight are primary metabolites. The ultimate result of either means of defense is pathogenesis or resistance. Plant defense mechanisms can be grouped either into inducible and constitutive defense or chemical, structural and morphological defense. Majority of defense mechanisms have a passive role, i.e. only defensive against pathogens, but a few are very active. Plant primary metabolites are catching interest in their immunity role. Deep information of molecular mechanisms involved during the plant-pathogen system is need of the day for future disease control. This review will highlight the role of primary metabolites and their mechanism of action in plant defense. • Plants synthesize diversity of Primary metabolites. • Primary metabolites prominently functions growth, development and reproduction of cell. • Primary metabolites perform their function as molecules signaling to trigger defense response. • We have highlight the new trends in utilizing primary metabolites for controlling bacterial, viral and fungal pathogens and insects.
