A novel psbA mutation (Phe 274-Val) confers resistance to PS2 herbicides in wild radish” was published in Pest Management Science, 2019, Vol 75, pp 144-151. One particularly famous psbA gene mutation (Ser-264 Gly) has been known for decades and has evolved in many parts of the world and gives resistance mainly to triazine herbicides but not to phenyl urea PS2 herbicides. As well as identifying this Ser-264-Gly mutation in wild radish in Australia in this work Huan Lu identified a new mutation of the psbA gene, Phe-274-Val. This Phe-274-Val mutation endows modest resistance to triazines, metribuzin and to certain phenyl urea herbicides.
