重金属污染是指由于人类对矿山过度开采、金属冶炼与加工及其它化工操作，造成的铅（Pb）、汞（Hg）、镉（Cd）、铬（Cr）等重金属以各种形式进入生态环境中，在其中留存、积累和迁移而造成的生态污染，土壤重金属污染的治理已成为目前环保关注的焦点。植物在长期进化过程中形成了根系富集、细胞壁束缚、跨膜转运等多种应对重金属胁迫的应答机制。microRNA(miRNA)是一类调控基因表达的重要小分子RNA，通过调控靶基因的表达而参与植物的生长发育、胁迫应答等生理代谢活动，它们同样在植物应答重金属胁迫过程中发挥重要作用。该研究对土壤中重金属污染现状进行了综述，并阐述了重金属胁迫条件下相关miRNA表达调控情况，以期为更好地研究植物miRNA应答重金属胁迫的调控机制提供参考依据。
- Abstract:
-
Heavy metal pollution is the ecological pollution caused by the heavy metals such as lead (Pb)，mercury (Hg)，cadmium (Cd) and chromium (Cr).These various forms of heavy metals get into the ecological environment due to human over-exploitation of the mining，metal smelting，and processing as well as other chemical operations，and they could retent，accumulate and migrate into the ecological environment.The treatment of soil heavy metal pollution has become the focus of environmental protection.In the long evolutionary process，plants have formed diverse mechanisms to deal with the heavy metal stress such as root-enriching，wall-bounding and membrane-transporting.microRNA (miRNA) are an important class of small RNA molecules involved in the growth and development，stress-responsing，and other physiological and metabolic activities of plants by regulating expression of the target genes.They also played an important role in the process of dealing with the heavy metal stress in plants.In this study，the situation of heavy metal pollution and regulation of miRNA expression under heavy metal stress were reviewed.It could provide references for better studying the responsive and regulatory mechanisms of plant miRNA.
