Significance Statement Evolution of herbicide resistant weeds is a global challenge looming particularly over grain crops that help feed the world. Of greatest concern is that cytochrome P450s capable of herbicide metabolism can endow cross‐resistance to herbicides of different modes of action/chemistries. Such a P450 gene ( CYP81A10v7 ) conferring metabolic resistance to herbicides of at least five modes of action was identified and characterized from a Lolium rigidum population, greatly advancing our knowledge on metabolic herbicide resistance.
