The sequence spectrum of frameshift reversions obtained with a novel adaptive mutation assay in Saccharomyces cerevisiae

Research on the mechanisms of adaptive mutagenesis in resting, i.e. non-replicating cells relies on appropriate mutation assays. Here we provide a novel procedure for the detection of frameshift-reverting mutations in yeast. Proliferation of non-reverted cells in this assay is suppressed by the lack of a fermentable carbon source. The test allele was constructed in a way that the reversions mimic microsatellite instability, a condition often found in cancer cells. We show the cell numbers during these starvation conditions and provide a DNA sequence spectrum of a representative set of revertants. The data in this article support the publication "Glucose starvation as a selective tool for the study of adaptive mutations in Saccharomyces cerevisiae" (Heidenreich and Steinboeck, 2016) [1]
