Mycorrhizal Fungi

Mycorrhizal Fungi

Why it Matters? 

  • A new global underground atlas reveals hidden biodiversity hotspots of mycorrhizal fungi, vital for plant health and ecosystem resilience, using machine learning and DNA analysis. 

What You Should Know?   

  • Mycorrhizae are beneficial fungi that form symbiotic relationships with plant roots. 

  • In this mutual exchange, fungi take sugars from plants and provide water and essential nutrients from the soil. 

Types of Mycorrhizal Fungi: 

  • Ectomycorrhiza: 

  • Live on root surfaces, mostly in trees (e.g., pine, beech). 

  • Form visible sheaths and toadstools; nutrient exchange. 

  • Endomycorrhiza (VA mycorrhiza): 

  • Live inside root cells, common in herbs and crops. 

  • Use arbuscules and vesicles for nutrient exchange and storage. 

Functions of Mycorrhizal Fungi: 

  • Increase nutrient absorption (especially phosphorus) by extending root surface area. 

  • Help plants survive in nutrient-poor or uncultivated soils. 

  • Enhance resistance to root diseases and environmental stress. 

  • Improve water uptake, especially in drought-prone conditions.
