In this study, a greenhouse experiment was conducted to investigate the effects of arbuscular mycorrhizal fungi (AMF) inoculation on Cd and Cu accumulation in maize under Cd-Cu combined pollutions, as well as the potential toxic effects of Cd-Cu pollution on AM symbiosis. It is shown that the heavy metal contamination significantly inhibits the symbiosis between AMF and maize (P<0.05), and the inhibition effects are more significant on the vesicle and arbuscular structures than on the hyphal structure of AMF. The heavy metal contamination also significantly inhibits the growth of maize (P<0.05), but the inhibition effects are obviously alleviated by AMF colonization. Besides, AMF inoculation significantly increases the Cd and Cu accumulations in both roots and shoots of host plants (P<0.05). The results from this study indicate that mild-to middle-levels of heavy metal contaminations in the agricultural soils could threat both crops and AMF. In the heavy metal contaminated farmlands, AMF could on one hand improve the tolerance of crops to heavy metals, while on the other hand increase the risks of heavy metals entering into human food chain by improving the heavy metal absorption of crop plants., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=lHGTqO5I/iSxAEmAxUAAaw==, pdfFileSize=2502862, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
