Abstract: In a symbiotic relationship, Arbuscular Mycorrhizal Fungi (AMF) enhance the host’s absorption of nutrients such as phosphate and nitrate while the heterotrophic fungal partner is provided with photosynthates from the host plant. Mycorrhiza-induced resistance, or MIR, is a trait of AMF-colonized plants that is attributed to a variety of mechanisms, including enhanced plant nutrition, altered root morphology and rhizosphere environment, controlled synthesis of secondary metabolites, competition for invasion sites and nutrients, stimulation of the plant defense system to elicit defense responses that include morphological, biochemical, and molecular ones, thus effectively managing fungal diseases. Therefore, in sustainable agriculture, AMF can be employed as an important tool in integrated crop disease management.
Keywords: AMF, defense responses, mechanisms, phyto pathogenic fungi
