Quizalofop-resistant wheat: biochemical characterization of the AXigen™ trait and corresponding metabolism
Altmetrics
Abstract
A new weed management tool in wheat, the CoAXium™ Wheat Production System, incorporates quizalofop-resistant wheat, a specialized formulation of quizalofop (Aggressor™), and a stewardship management program for effective management of annual grasses with otherwise limited control options. The AXigen™ trait confers resistance primarily through a single-point mutation in ACC1. The mutation causes an alanine to valine substitution at position 2004 in wheat acetyl-CoA carboxylase (ACCase) relative to the Alopecurus myosuriodes reference. Through greenhouse and biochemical studies paired with protein ...
