Arbuscular Mycorrhizal (AM) symbiosis is integral to sustainable agriculture and enhances plant resilience abiotic biotic stressors. Through their symbiotic association with roots, AM improves nutrient water uptake, activates antioxidant defenses, facilitates hormonal regulation, contributing improved health productivity. Plants release strigolactones, which trigger spore germination hyphal branching, a process regulated by genes, such as D27 , CCD7 CCD8 MAX1 . recognition plants mediated receptor-like kinases (RLKs) LysM domains, leading the formation of arbuscules that optimize exchange. Hormonal regulation plays pivotal role in this symbiosis; cytokinins enhance colonization, auxins support arbuscule formation, brassinosteroids regulate root growth. Other hormones, salicylic acid, gibberellins, ethylene, jasmonic abscisic also influence colonization stress responses, further bolstering resilience. In addition health, soil improving microbial diversity, structure, cycling, carbon sequestration. This supports pH pathogen suppression, offering alternative chemical fertilizers fertility. To maximize ’s potential agriculture, future research should focus on refining inoculation strategies, enhancing compatibility different crops, assessing long-term ecological economic benefits. Optimizing applications critical for agricultural resilience, food security, farming practices.
