RESUMO
A rapid method for Tn5 mutagenesis of cloned genes on multicopy plasmids was used to map a yeast ILV2 mutant allele encoding a sulfometuron methyl-resistant acetolactate synthase. Twenty-one of 40 independent Tn5 insertions were within the 5.6-kilobase-pair cloned segment. Of these, seven adjacent transposition events inactivated the sulfometuron methyl resistance determinant, localizing the ILV2 gene to a minimum 1.4-kilobase-pair region.
