Historically research on mycorrhizal associations has been centered on the effects of the symbiosis in individual plants, especially on the improvement of acquisition of dissolved mineral nutrients such as phosphorus P. This contribution becomes fundamental in the establishment and growth of plants which develop in adverse conditions such as arid zones with low fertility Jamil Mohammad et al., 2003, because it increases the access of the plant roots to nutritional elements such as P and nitrogen N and to essential metals such as copper Cu and zinc Zn Smith and Read, 2008.
