Synergistic interactions of am fungi with essential groups of microbes in plant growth promotion

The exploitation of AM fungi is highly significant to massive crop improvement programmes. It is important to withstand drought in the nursery and in the field. Improved growth of many crops, resistance of plants to drought stress and root pathogens due to application of AM fungi was emphasized by many workers. Considerable research efforts have been made to demonstrate that Mycorrhizal and N2 fixing symbionts benefit the plant growth and these two symbionts can be used in agriculture to improve nursery quality and subsequent growth in the field. Rhizosphere microorganisms influence many chemical reactions by way of their metabolites and AM fungi play a crucial role in affiliating both microbial and plant functions as mediators of exchange between them. Because of the added advantage by the interaction between AM and different groups of microbes, Mycorrhizal technology has assumed greater relevance in crop production. The practical application can lead to potential increase in survival and growth rates of crops. This paper traces synergistic interactions of AM with other microbes that promote plant growth.
