Use of Arbuscular Mycorrhizal Fungí for Biocontrol of Soilborne Fungal Plant Pathogens

Abstract

A key and universally accepted concept is that natural microbial populations in soil or other living substrates are associated with growth around developing plant roots, giving rise to the so-called rhizosphere (Azcón-Aguilar and Barea, 1992). As a rhizosphere develops at the root-soil interface, microorganisms there interact with both plant roots and soil constituents. Communication among these components is mainly via chemical or biochemical signals, although physical interaction is also possible (Azcón-Aguilar and Barea, 1996). © 2007 by The Haworth Press. Inc.
