杂草对百草枯的抗药性机制研究进展

百草枯抗性杂草的产生严重危害粮食生产并间接加重环境污染。本文综述了近年来多种抗百草枯杂草的发生、发展与危害等方面的研究进展,重点对转运体与杂草抗药性关系、百草枯的限制隔离机制、抗氧化酶保护作用进行了分析,并从光照对抗性机的制影响和杂草抗药性遗传规律等方面对百草枯的抗性机制展开了讨论,认为未来中国存在出现大规模抗百草枯杂草的风险,提出了延缓杂草对百草枯产生抗性的策略。

Research advances in paraquat-resistance mechanisms of weeds

The infestation of paraquat-resistant weeds can cause serious damage to food production,and indirectly increase environmental pollution.This paper reviewed the recent years’ research advances in the occurrence,development,and damage of paraquat-resistant weeds,and discussed the mechanisms of paraquat-resistant weeds,with the focus on the relationship between transporter and resistance,restriction and isolation,protective effect of antioxidant enzymes,influence of light on resistant mechanisms,and genetics of paraquat resistance.It was considered that there would be an outbreak risk of paraquat-resistant weeds in China in the future,and the strategies of delaying the occurrence of paraquat-resistant weeds were suggested.
