摘　　要：二苯醚类除草剂是一类广谱、高效、高选择性的除草剂,广泛应用于大豆、花生等农田一年生和多年生阔叶杂草的防除。由于该类除草剂不易降解,多年连续使用会导致其在土壤环境中的大量积累。本文概述了二苯醚类除草剂的基本结构及其对生物的影响,总结了降解二苯醚类除草剂的微生物种类、降解途径和降解过程中关键酶及其基因,分析了影响微生物降解二苯醚类除草剂的因素,对二苯醚类除草剂微生物降解未来的研究方向进行了展望,为深入研究二苯醚类除草剂的生物降解提供参考。Diphenyl ether herbicides,a group of broad-spectrum herbicides with high efficiency and high selectivity,have been widely used for controlling annual and perennial broad-leaved weeds in soybean and peanut fields.The continuous use of these herbicides for years may lead to significant accumulation in the soil environments.In this paper,we briefed the basic structures of diphenyl ether herbicides and their impacts on organisms,summarized the microbial species capable of degrading diphenyl ether herbicides,degradation pathways,and the key enzymes and genes involved in the degradation of diphenyl ether herbicides,and analyzed the factors affecting the microbial degradation.Finally,the future research trends in microbial degradation of diphenyl ether herbicides were presented.This paper aims to provide references for further research on the biodegradation of diphenyl ether herbicides.
