VAM-Fungi and their Interactions with other Microorganisms
With relatively few exceptions roots of agricultural plants are infected by vesicular-arbuscular mycorrhizal fungi (VAMF). The mycorrhiza affects other soil microbes, and other microbes affect VAM. This symbiosis may also influence the general resistance of plants to pathogens. The mycorrhizal endophytes as well as root pathogens in the soil environment are part of a complex interacting system. Host plants inoculated with VAMF have been shown to exibit increased resistance to fungal root diseases and wilts. On the other hand diseases on green parts of the plants are usually more severe in mycorrhizal plants indicating that VAM changes the physiology of the whole plant. In the light of the present knowledge VAM is discussed with regard to the use in plant production.
