The paper “Metribuzin resistance in a wild radish population via both psbA mutation and enhanced metabolism” by Lu, Yu, Han, Owen & Powles, was published in Journal of Agricultural & Food Chemistry, 2019, Vol. 67, pp 1353-1359.
This paper identifies multiple mechanisms: as well as psbA gene mutation there is a non-target site resistance mechanism of enhanced metabolism. Of course, we expect multiple mechanisms of herbicide resistance as evident here in both target site psbA gene mutation and non-target site enhanced metabolism resistance. In his current studies, Huan Lu is documenting that this non-target site enhanced metabolism resistance endows resistance to other very different herbicides. This information will become available in Huan’s next publication.
