Most cells spend the majority of their life in the non‐proliferating, quiescent state. Transition to this state is crucial for microorganisms to survive long starvation periods and restart divisions afterwards. Experimental evolution allowed us to identify several mutation in genes that are presumably important for such transition in yeast cells. Most of these candidate genes belong to the SPS amino...
Coevolution between different biological entities is considered an important evolutionary mechanism at all levels of biological organization. Here, we provide evidence for coevolution of a yeast killer strain (K) carrying cytoplasmic dsRNA viruses coding for anti‐competitor toxins and an isogenic toxin‐sensitive strain (S) during 500 generations of laboratory propagation. Signatures of coevolution...
Cellular aggregates observed during growth of Saccharomyces cerevisiae strains derived from various natural environments makes most laboratory techniques optimized for non-aggregating laboratory strains inappropriate. We describe a method to reduce the size and percentage of the aggregates. This is achieved by replacing the native allele of the AMN1 gene with an allele found in the W303 laboratory...
