AMF AND CLIMATE CHANGE PERSPECTIVES
The main areas, in which the benefits of introducing inoculant AMF into
a plant growth system will accrue, are those in which they are lacking in-
digenous inoculum of AMF. Many manipulation experiments focusing on
climate change impacts on ecosystem functioning were conducted under
controlled conditions, without considering the mycorrhizal fungi living in
symbiosis with the plants. Under such situation, indirect AMF effects on
root exudation, root longevity and decomposition, soil aggregate stabil-
ity, and nutrient acquisition are probably crucial as well. In this context,
recent research that highlighted the central role of mycorrhizal fungi may
play regarding feedbacks on global change. Arbuscular mycorrhizal fungi
also are sensitive to climate change. Elevated CO

concentrations can in-
directly affect AMF through increased C allocation from the host plant to
the fungus a temperature-induced increase in fungal growth was associ-
ated with increased specific root length. Photosynthates were more rapidly
