Despite previous research on mycorrhizal association with plants, the data on associations with coffee (Coffea species) are very sparse despite the great economic importance of this crop for many tropical developing countries. The present paper reviews the main aspects of the association between arbuscular mycorrhizal fungi (AMF) and coffee plants. This review includes topics on mycorrhizal effects on coffee nutritional status, pathogenAMF interactions and responses to several environmental stresses. It also summarizes findings about the natural occurrence of AMF in different soils in which coffee is cultivated, some ecological aspects of this specific association and outlines trends for future investigations, which must elucidate the real benefits of mycorrhizae to coffee plants. © 2009 Copyright Cambridge University Press.1472105115Aguín, O., Mansilla, J.P., Vilariño, A., Sainz, M.J., Effects of mycorrhizal inoculation on root morphology and nursery production of three grapevine root- stocks (2004) American Journal of Enology and Viticulture, 55, pp. 108-111Aliasgharzadeh, N., Saleh Rastin, N., Towfighi, H., Alizadeh, A., Occurrence of arbuscular mycorrhizal fungi in saline soils of the tbriz pain of Iran in relation to some physical and chemical properties of soil (2001) Mycorrhiza, 11, pp. 119-122Alloway, B.J., (2004) Zinc in Soils and Crop Nutrition, , http://www.zincworld.org/Documents/Communications/Publications/ ALLOWAY-PRINT.pdf, Belgium: International Zinc Association (IZA).
