Mutations in Chlamydomonas reinhardtii Conferring Resistance to the Herbicide Sulfometuron Methyl



Mutations in Chlamydomonas reinhardtii Conferring Resistance to the Herbicide Sulfometuron Methyl



Plant Physiology 85(4): 898-901



C. reinhardtii mutants resistant to sulfometuron methyl (SM) were isolated and characterized. Growth of C. reinhardtii was sensitive to inhibition by SM at a concn of 1 micro M. Four mutants resistant to 10- to 100-fold higher concn were isolated. All possessed a form of acetolactate synthase (ALS) whose specific activity in cell extracts was 100- to 1000-fold more resistant to SM than the specific activity of the wild-type enzyme.
