Rice production in India faces significant constraints from water stress due to climate change, affecting approximately 6 million hectares of upland rain-fed rice fields. Arbuscular mycorrhizal fungi form symbiotic relationships with rice plants and can help combat the effects of water stress by establishing a hyphal network that improves water and nutrient exchange, activates stress response genes, and increases the accumulation of proline and ABA signaling to help rice plants better tolerate dry conditions. Through these mechanisms, pairing rice with AM fungi shows potential as a novel approach for improving rice yields under water-limited conditions.

- 5. Arbusclar Mycorrhiza • Effective microbial technology in aerobic rice cultivation • Symbiont with vascular plants. • The fungus forms highly branched structures for nutrient exchange with the plant called "arbuscules“. • Arbuscules are the sites of exchange for phosphorus, carbon, water, and other nutrients
