Question

Write a short note on Role of VAM in crop improvement.

Answer 1

Vesicular-arbuscular mycorrhizal (VAM) fungi form symbiotic associations with the roots of plants, where they penetrate the root cortex and develop vesicles and arbuscules. VAM fungi, especially those from the genus Glomus, play a crucial role in crop improvement by enhancing the absorption of essential nutrients such as phosphorus and copper. They also help plants resist drought and certain root-infecting pathogens. Due to these benefits, VAM fungi are considered natural allies in agriculture, aiding in nutrient uptake efficiency and improving crop resilience, thereby contributing to better crop growth and yield.
