Abstract
Mycorrhizal fungi form a symbiotic association with the roots of most plants, and significantly alter the morphology and physiology of the plant. Among other physiological changes, root exudation is qualitatively and quantitatively altered, and thus the microbial composition of the rhizosphere changes. The kinds of microbial interactions that occur in the ‘mycorrhizosphere’ are often reflected in plant responses as a result of the combination of mycorrhizae and their microbial associates. Mycorrhiza-microbial interactions may be direct between organisms, or indirect as mediated by the host plant. For example, plant growth and health may be influenced when mycorrhizal fungi interact with the general microflora, or with specific microbes such symbiotic and free-living nitrogen-fixing bacteria, nutrient solubilizing bacteria, fungal and bacterial biocontrol agents, and other fungi. These associations and interactions occur naturally but to varying degrees in most soils. Those with positive effects on crop plants can be managed by inoculation with microbial combinations selected for their compatibility and combined effects.
