植物-微生物联合修复重金属的研究进展

重金属污染严重威胁到农作物安全和人体健康。植物修复重金属污染方面已有大量研究，其中植物-微生物联合修复被认为是改善重金属含量的一种有效方法。就近年来植物-微生物联合修复重金属的机理进行了评述，总结了近5年植物-微生物联合修复应用于重金属污染的研究。植物与微生物的协同作用，微生物与植物间形成联合体可以在很大程度上减轻环境对植物的影响。此外，微生物通过提高植物的抗性、降低重金属毒性、促进植物生长等方式增强植物修复重金属的能力。由于污染环境的复合性和复杂性，未来植物-微生物-金属相互作用的分子机制研究和开发植物-微生物联合修复的新技术开发将会成为重点。

Research Progress of Plant-Microbe Combined Phytoremediation of Heavy Metals

Heavy metal contamination is a serious threat to crop safety and human health. A lot of researches on phytoremediation of heavy metal pollution have been conducted; among which microbial combined phytoremediation is considered an effective method to improve the heavy metal content. The mechanisms of microbial combined phytoremediation of heavy metals in recent years were reviewed. The researches on microbial combined phytoremediation applied to heavy metals in the past five years were summarized. The formation of a consortium between microorganisms and plants and the synergistic effect of plants and microorganisms can largely mitigate the environmental impact on plants to a great extent. In addition, microorganisms enhance the ability of plants to remediate heavy metals by enhancing plant resistance, promoting plant growth and reducing heavy metal toxicity. Due to the complex nature and complexity of the polluted environment, the research on the molecular mechanism of plant-microbial-metal interaction and the development of new technology for microbial combined phytoremediation will become the focus of research in the future.
