Arbuscular mycorrhizal (AM) association constitutes an important component of soil microbial com-munity belongs to the fungal phylum Glomeromycota. They improve plant growth, nutrient uptake, promote plant diversity, help in rehabilitation and reclamation of waste land, biohardening, phytoremediation, soil aggregation and also help to control plant pathogens. Their diversity and composition vary among different habitat of the globe. They occur in a wide spectrum of agricultural crops, most shrubs, tropical tree species and some temperate tree species. It has been found in some gymnosperms, pteridophytes, bryophytes and in some floating and submerged aquatic plants. It is important to study biodiversity of such beneficial fungi from efficient utilization and conserva-tion point of view.
