Sgs1 controls the fidelity of gene targeting

Introduction of linear, non replicative DNA fragments is widely used for the replacement of homologous sequences in the yeast genome. Moreover, it is studied as a general model for genetic manipulations by ends-out recombination. It is generally assumed that, in contrast to higher eukaryotes, transformation of the yeast Saccharomyces cerevisiae with non replicative DNA occurs almost exclusively by homologous recombination. We found out that the ends-out recombination may result in different genetic alterations in the yeast genome (1). Three clases of events were identified: illegitimate integration, integration of the transforming DNA next to the targeted region and disomic, heteroallelic transformants containing starting allele and allele expected after succesful gene targeting. We performed a systematic study of the influence of type of gene modification (insertion, replacement and deletion) on the accuracy of ends-out recombination.
