Quantification of AMF-induced modifications to root system architecture and longevity

The growth of a functional root system is essential to the development and survival of terrestrial plants. Obvious functions include anchorage and nutrient and water uptake but other, less obvious, functions such as sites for symbiotic and pathogenic microorganisms are also important and may in some circumstances be critical. Plant roots are also very important to the soil ecosystem, providing not only a physical niche for many soil organisms but, through exudation and mortality, a major source of carbon.
