BIOACTIVE NATURAL COMPOUNDS AS ELICITORS OF PLANT DEFENSE AGAINST BACTERIAL PATHOGENS

Traditional plant disease management measures are losing efficacy, and pesticide resistance in pathogens is increasing, posing a serious risk to global food security. The availability of bioactive natural compounds (BNCs) in our ecosystem opens up new possibilities for sustainable crop protection and organic agriculture. In crop disease management, the use of biologically active substances obtained from nature efficiently protects plants from infections and induces improved immunity against pathogenic strains. This review focuses on the properties and mechanism of some bioactive compounds in inducing host defense as well as their mode of action against pathogen. This review also seeks to elucidate the induced host-defense mechanism and the effectiveness of BNCs in eliciting defensive responses in plants against plant pathogenic bacteria.
