What is Mycorrhiza: Classification of Mycorrhizae II Free study material II LetsBloom Study material II ROOT ANATOMY IN RELEATION TO MYCORHIZA

 INTRODUCTION:

• When plants live in challenging location then some kind of mechanism help them to survive .
• One important set of survival mechanism involve creating mutual beneficial relationship (SYMBIOTIC) between plant roots and soil borne bacteria. Such as in between fungi and roots .
• The association between roots and fungi is called as MYCORHIZA
• Mycorrhizal fungi are heterogenous group of diverse fungal taxa associated with roots of around 90% of plants species.
• The term Mycorrhiza means: 
• MYCO:-Fungi
• RRHIZA: Roots

• Thus, mycorrhizae are the symbiotic associa­tions between plant root and fungi, with bidirectional nutrient exchange between the partners.

FEATURES OF MYCORHIZA

• Mycorrhizal fungi colonize environments such as alpine and boreal zones, tropical forests, grasslands and croplands.
• They have a major role in nutrient cycling through the specific activity of their mycelium in absorbing soil nutrients and supplying them to the plant .
• Mycorrhizal fungi develop an extensive hyphal network in the soil, the aptly named wood-wide web4, which can connect whole plant communities offering efficient horizontal transfer of nutrients.
• Mycorrhizas develop specialized areas, called symbiotic interfaces, to interact with the host.
• They lack any Phyto pathological symptoms in the partners during the active phase of mutualism.
