| Abstract: | A brief introduction of environmental and ecological characteristics of hyperaccumulators of rare earth elements(REEs),as well as the scientific significance of REE hyperaccumulators were presented.Based on this,the achievements in REE hyperaccumulator research:(1) The species and regional distribution of REE hyperaccumulators,(2) Distribution and fractionation of REEs and their influence factors in hyperaccumulators were reviewed in detail,(3) Physiological and biochemical mechanisms of REE uptake by hyperaccumulators were reviewed.Furthermore,future directions in REE hyperaccumulator research and the remediation potential of REE hyperaccumulators were discussed. |
