Genetic screen identifies adaptive aneuploidy as a key mediator of ER stress resistance in yeast [Cell Biology]

The yeast genome becomes unstable during stress, which often results in adaptive aneuploidy, allowing rapid activation of protective mechanisms that restore cellular homeostasis. In this study, we performed a genetic screen in Saccharomyces cerevisiae to identify genome adaptations that confer resistance to tunicamycin-induced endoplasmic reticulum (ER) stress. Whole-genome sequencing of...
