A naturally evolved mutation (Ser-59-Gly) in glutamine synthetase confers glufosinate resistance in plants

Glufosinate is an important and widely used non-selective herbicide active on a wide range of plant species. Resistance evolution to glufosinate in weedy plant species (including the global weed Eleusine indica) is underway. AHRI researchers established the molecular basis of target-site glufosinate resistance in Eleusine indica.
