Arbuscular Mycorrhizal Fungi Increase Pb Uptake of Colonized and Non-Colonized Root and Deliver Extra Pb to Colonized Root Segment.

Arbuscular mycorrhizal (AM) fungi establish symbiosis and improve the lead (Pb) tolerance of host plants. The AM plants accumulate more Pb in roots than their non-mycorrhizal counterparts. However, the direct and long-term impact of AM fungi on plant Pb uptake has been rarely reported.
