Abstract

Arbuscular mycorrhiza-forming fungi make necessary feeding upon the host plant cells without killing the plant and derive their food from host-plant. Arbuscular mycorrhiza generates the mass on the root cells and forms some peculiar structures (arbuscules) within the cell. These cell structures are actually the sites where the give-and-take of nutrients between the fungi and plant takes place. Extracellular networks which spreads in all possible directions into the surrounding soil and reach to locations where nutrient concentration is very low and make available food, minerals and other nutrients exclusively PO42− and NO3− for the plant. The host plant provides the symbiotic partner food for life activities. Arbuscular mycorrhiza-forming fungi provides sustainable soil health by improving soil structure, defence mechanism against plant root pathogens, provide availability of essential plant nutrients (Zn, Cu, Fe, Ca, Mg and NPK), tillage, bio-control of pests and play efficient role in phytoremediation.
