功能内生细菌对植物体内有机污染物代谢的影响

Effects of Endophytic Bacteria on the Metabolism of Organic Pollutants in Plant

土壤有机污染危及农产品安全和人体健康。筛选具有降解有机污染物功能的植物内生细菌,并将其定殖于植物体,有望调控植物体内有机污染物的代谢过程,从而有效地规避植物有机污染的风险,相关研究受到国内外研究者的关注。通过综述近年来有关具有有机污染物降解功能的植物内生细菌分离、筛选的研究进展,分析了功能内生细菌对植物体内有机污染物代谢的影响,揭示了功能内生细菌调控植物体内有机污染物代谢的机理,为进一步利用内生细菌调控植物有机污染的风险提供了思路和依据。

Soil organic contamination has become a worldwide environmental problem, posing great threats to agricultural products and hu- man health. Utilizing endophytic bacteria to control the metabolism of organic pollutants in plant and effectively reduce the risk of plant or- ganic contamination attracts much attention. In this paper, the isolation and screen of endophytic bacterial strains with the function of degra- dation of organic pollutants were reviewed. The effects of the functional endophytic bacteria on the metabolism of organic contaminants in plants were elucidated, and the mechanisms involved were clarified. This study provides a new perspective that the application of endophytic bacteria potentially decreases the accumulation of organic contaminants in plants, hence reducing the risks to food safety and human health.
