Summary

This volume contains a selection of papers presented at the Rothamsted Millennium Conference "Interactions in the Root Environment - an Integrated Approach". The meeting brought together scientists from a range of disciplines interested in the relationship between soil biology and plant growth, reflected by the contents of the volume. Topics range from root development and nutrient flow, plant-microbe and plant-plant signaling, methods for studying bacterial and fungal diversity, to the exploitation of rhizosphere interactions for biological control of diseases and soil remediation. Authors include many internationally-recognized experts in their field and the contributions range from reviews to research papers. The volume presents a timely and wide-ranging overview of the interactions between plants, microbes and soil. It should prove an indispensable resource for students and others seeking an introduction to the topic, in addition to scientists already conversant with the area of research.
