Plasmid-chromosome shuffling for non-deletion alleles in yeast.

Abstract

Here we describe a facile plasmid-chromosome shuffling technique for generating and analyzing non-deletion alleles in the yeast Saccharomyces cerevisiae. This technique takes advantage of an existing set of genome-wide haploid-convertible heterozygous diploid yeast knockout mutants. This simple method will facilitate characterization of essential gene functions and genome-wide investigation of protein structure-function relationships.
