Role of Arbuscular Mycorrhizal Fungi in Regulating Growth, Enhancing Productivity, and Potentially Influencing Ecosystems under Abiotic and Biotic Stresses

Plants, Journal Year: 2023, Volume and Issue: 12(17), P. 3102 - 3102

Published: Aug. 29, 2023

Arbuscular mycorrhizal fungi (AMF) form symbiotic relationships with the roots of nearly all land-dwelling plants, increasing growth and productivity, especially during abiotic stress. AMF improves plant development by improving nutrient acquisition, such as phosphorus, water, mineral uptake. tolerance resilience to stressors drought, salt, heavy metal toxicity. These benefits come from arbuscular interface, which lets fungal partners exchange nutrients, signalling molecules, protective chemical compounds. Plants' antioxidant defence systems, osmotic adjustment, hormone regulation are also affected infestation. responses promote performance, photosynthetic efficiency, biomass production in stress conditions. As a result its positive effects on soil structure, cycling, carbon sequestration, contributes maintenance resilient ecosystems. The AMFs ecological stability species- environment-specific.
