The optimal crop development demands a higher application of mineral fertilizers and pesticides. The use of such chemicals involves not only high cost and energy requirements, but their indiscriminate contribution could cause salinity troubles and ground water pollution. Plant development can also be improved by using biological elements that co-ordinately act in the soil-root interface; among them and as an essential factor are arbuscular mycorrhizal fungi, which are capable of colonizing 95 % land plants. A recent study on the microbial community associated to arbuscular mycorrhizal fungi (AMF) has provided a fungal knowledge; bacteria, filamentous fungi and yeast associated to AMF structures have been observed. This paper is aimed to analyze the evident tripartite interaction between AMF, plants and other microorganisms, and to release the main scientific contributions associated to this phenomenon.
