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.
