Duplicates are more enriched for transcriptional plasticity than singletons, regardless of the mechanism of duplication. (a) Transcriptional plasticity of duplicates and singletons in S. cerevisiae. Y-axis represents the mean percentage of genes with altered transcription across four stress conditions (ethanol, glycerol, lactate and oxidative stress in a medium supplemented with dextrose). We also compared WGDs and SSDs to singletons. Significant differences were found using Fisher’s exact test, with *** indicating a probability of P < 2.2 × 10−16. (b) Venn diagram representing the overlap in the number of duplicates and singletons between C. glabrata and S. cerevisiae.
