Transformation with a mutant arabidopsis acetolactate synthase gene renders tobacco resistant to sulfonylurea herbicides



Transformation with a mutant arabidopsis acetolactate synthase gene renders tobacco resistant to sulfonylurea herbicides



Molecular & General Genetics 211(2): 266-271



A gene encoding acetolactate synthase was cloned from a chlorsulfuron-resistant mutant of Arabidopsis. The DNA sequence of the mutant gene differed from that of the wild type by a single base pair substitution. When introduced into tobacco by Ti plasmid-mediated transformation the gene conferred a high level of herbicide resistance. These results suggest that the cloned gene may confer agronomically useful levels of herbicide resistance in other crop species, and that it may be useful as a selectable marker for plant transformation experiments.
