Effect of valine and the herbicide sulfometuron methyl on acetolactate synthase activity in nuclear and plasmid-borne sulphometuron methyl resistant Saccharomyces cerevisiae strains.

Acetolactate synthase ( ALS) specific activity was evaluated in isogenic lines of Saccharomyces cerevisiae carrying the wild-type ILV2 gene or mutations in this gene for resistance to the herbicide sulfometuron methyl (SM). Statistical comparisons were made between two nuclear alleles and among five alleles borne on a YE chimaeric plasmid transformed into a strain carrying a 1.5-kilobase deletion in the nuclear ILV2 gene. Decreased ALS activity of plasmid-borne SM-resistant mutations was shown not to be caused by copy number effects. ALS-specific activity in strains carrying the wild-type ILV2 allele exhibited strong feedback inhibition by valine and was sensitive to SM. All nuclear and plasmid-borne SM-resistance alleles resulted in ALS-specific activity highly resistant to SM and resistant to valine feedback inhibition.[1]
