Saccharomyces cerevisiae articles from across Nature Portfolio

Protein aggregates are a hallmark of neurodegenerative disease and aging. Here, Fischbach et al. report engineered, artificial systems to re-localise or export protein aggregates from cells, with preliminary data showing that mHtt inclusions in S. cerevisiae may be cytotoxic.

Here, the authors describe the geographies, hosts, substrates, and phylogenetic relationships for 1,794 Saccharomyces strains. They provide insight into the genetic and phenotypic diversity in the genus, not seen through prior work focused on the model species Saccharomyces cerevisiae.

Antibiotic and anti-cancer therapy are challenged by mutation-mediated treatment resistance despite many mutations being maladaptive. Here, the authors introduce a system that shows how the probability of the long-term persistence of drug-resistant mutant lineages can be increased in dense microbial populations by acquiring multiple mutations.

Increasing the number of chromosome sets alters the physiology of cells. Here, the authors show that although the number of chromosome sets increases, the proteome does not scale linearly with the increasing ploidy.

Microbial production of cannabinoids promises a cheaper and more sustainable route to these important therapeutic molecules, but strain improvement and screening is challenging. Here, the authors develop a yeast-based Δ9-tetrahydrocannabinol (THC) biosensor for screening microbial mutant libraries.
