title: [Effects of copper stress on the function of arbuscular mycorrhizal fungi community].
abstract: The functional differences of arbuscular mycorrhizal fungi (AMF) isolates from different sources have been extensively investigated in the last two decades. However, previous studies were mostly based on individual AMF species and the community level comparison was not addressed properly. Furthermore, many studies did not distinguish the difference between the effects of AMF source and community structure on their function, let alone concerned the significance of host plant. This study evaluated the effects of copper (Cu) stress on AMF community structure and compared the differences of AMF communities from Cu contaminated and uncontaminated substrates on performance of Zea mays through two short-term greenhouse pot culture experiments. The results showed that spore abundance and composition of AMF communities were changed dramatically under Cu stress compared with the control. The communities dominated by Rhizophagus intraradices and Claroideoglomus etunicatum from Cu contaminated soils conferred more benefits on Z. mays in terms of plant growth and physiological properties relative to that from control governed by Funneliformis mosseae.
