Interpretive Summary: Evolution of herbicide resistance is an extension of natural selection whereas plants are able to overcome the strong pressure imposed by these synthetic phytotoxins. Plants can become resistant via several mechanisms that include physical changes resulting in reduced uptake, physiological changes resulting in compartmentalization or altered translocation, and/or biochemical changes that result in enhanced metabolism or in alterations of protein structures resulting in loss of sensitivity to the herbicides. This review highlights that many of these mechanisms are involved in the various cases of resistance to PDS and PPO inhibiting herbicides.
