Abstract

As one of the most widely used herbicides in the world, paraquat is used in weed control of many crops. Paraquat induces generation of reactive oxygen species (ROS) in the presence of light and desiccates the green parts of plants through a quick penetration from the leaf surface. In recent 50 years, the utility of paraquat has greatly benefited the development of no-tillage agriculture; meanwhile, enhanced tolerance to paraquat has been evolved in many weeds due to excessive use. Drawing information from researches on paraquat resistance in weeds and two model plants, Arabidopsis and tobacco, we propose two hypotheses illustrating the mechanisms of paraquat resistance: (1) sequestrating paraquata from target site in chloroplast; (2) increasing capability to scavenge ROS.
