Abstract
Bacterial endophytes are the internal association of bacteria with the plants, cherished whole or any part of their life cycle inside the plant. They are reported to improve plant health against the biotic stresses via de novo synthesis of structural compounds and stimulation of plant immunity. They are found to be vital in development of host resistance against phytopathogens and capable in reducing and elimination of deleterious effects of plant pathogens. Fungal-, bacterial-, viral-, insect- and nematode-associated negative effect can be reduced by the bacterial endophytes. They are also reported to control plant pathogens through several defense mechanisms such as by producing antimicrobial compounds and antibiotics, de novo synthesis of structural compounds, keeping out of pathogens by niche competition and induction of plant immunity or induced systemic resistance. In this review, an effort is made to summarize the exploitation of endophytic bacteria as a biological substitute to control biotic stresses in agricultural practices.
