Cadmium (Cd 2+ ) pollution occurring in salt-affected soils has become an increasing environmental concern in the world. Fast-growing poplars have been widely utilized for phytoremediation of soil contaminating heavy metals (HMs). However, the woody Cd 2+ -hyperaccumulator,  Populus  ×  canescens , is relatively salt-sensitive and therefore cannot be directly used to remediate HMs from salt-affected soils. The aim of the present study was to testify whether colonization of  P.  ×  canescens  with ectomycorrhizal (EM) fungi, a strategy known to enhance salt tolerance, provides an opportunity for affordable remediation of Cd 2+ -polluted saline soils. Ectomycorrhization with  Paxillus involutus  strains facilitated Cd 2+  enrichment in  P.  ×  canescens  upon CdCl 2  exposures (50 μM, 30 min to 24 h). The fungus-stimulated Cd 2+  in roots was significantly restricted by inhibitors of plasmalemma H + -ATPases and Ca 2+ -permeable channels (CaPCs), but stimulated by an activator of plasmalemma H + -ATPases. NaCl (100 mM) lowered the transient and steady-state Cd 2+  influx in roots and fungal mycelia. Noteworthy,  P. involutus  colonization partly reverted the salt suppression of Cd 2+  uptake in poplar roots. EM fungus colonization upregulated transcription of plasmalemma H + -ATPases ( PcHA4 ,  8 ,  11 ) and annexins ( Pc  ANN1 ,  2 ,  4 ), which might mediate Cd 2+  conductance through CaPCs. EM roots retained relatively highly expressed  PcHAs  and  PcANNs , thus facilitating Cd 2+  enrichment under co-occurring stress of cadmium and salinity. We conclude that ectomycorrhization of woody hyperaccumulator species such as poplar could improve phytoremediation of Cd 2+  in salt-affected areas.
