Saccharomyces cerevisiae × Saccharomyces uvarum hybrids generated under different conditions share similar winemaking features
Abstract
Interspecific hybrids among species in the Saccharomyces genus are frequently detected in anthropic habitats and can also be obtained easily in the laboratory. This occurs because the most important genetic barriers among Saccharomyces species are post‐zygotic. Depending on several factors, including the involved strains, the hybridization mechanism and stabilization conditions, hybrids that bear differential genomic constitutions, and hence phenotypic variability, can be obtained. In the present study, Saccharomyces cerevisiae × Saccharomyces uvarum hybrids were constructed using genetically and physiologicall...

Veni, vidi, vici: the success of wtf meiotic drivers in fission yeast
Abstract
Meiotic drivers are selfish DNA loci that can bias their own transmission into gametes. Due to their transmission advantages, meiotic drivers can spread in populations even if the drivers or linked variants decrease organismal fitness. Meiotic drive was first formally described in the 1950s and is thought to be a powerful force shaping eukaryotic genomes. Classic genetic analyses have detected the action of meiotic drivers in plants, filamentous fungi, insects, and vertebrates. Several of these drive systems have limited experimental tractability and relatively little is known about the molecular mechanisms of mei...

Gene ‐gene and gene‐environment interactions in complex traits in yeast
Abstract
One of the fundamental question in biology is how the genotype regulates the phenotype. An increasing number of studies indicate that in most cases, the effect of a genetic locus on the phenotype is context‐dependent, i.e. it is influenced by the genetic background and the environment in which the phenotype is measured. Still, the majority of the studies, in both model organisms and humans, that map the genetic regulation of phenotypic variation in complex traits primarily identify additive loci with independent effects. This does not reflect an absence of the contribution of genetic interactions to phenotypic v...

Yeasts of the soil – obscure but precious
Abstract
Pioneering studies performed in the 19th century demonstrated that yeasts are present in belowground sources. Soils were regarded more as a reservoir for yeasts that reside in habitats above it. Later studies showed that yeast communities in soils are taxonomically diverse and different from those above ground. Soil yeasts possess extraordinary adaptations that allow them to survive in a wide range of environmental conditions. A few species are promising sources of yeast oils and have been used in agriculture as potential antagonists of soil‐borne plant pathogens or as plant growth promoters.
Yeasts have been st...

Yeast ‐insect associations: it takes guts
Abstract
Insects interact with microorganisms in several situations, ranging from the accidental interaction to locate attractive food or acquisition of essential nutrients missing in the main food source. Despite a wealth of studies recently focused on bacteria, the interactions between insects and yeasts have relevant implications for both the involved parts. The insect intestine shows several structural and physiological differences among species, but it is generally a hostile environment for many microorganisms, selecting against the most sensitive and at the same time guaranteeing a less competitive environment to res...

History of Genome Editing in Yeast
Abstract
For thousands of years humans have used the budding yeast Saccharomyces cerevisiae for production of bread and alcohol, however only for the last 30‐40 years our understanding of the yeast biology has dramatically increased enabling us to modify its genome. Although S. cerevisiae has been the main focus of many research groups, other non‐conventional yeasts have also been studied and exploited for biotechnological purposes. Our experiments and knowledge have evolved from recombination, to high‐throughput PCR based transformations, to highly accurate CRISPR methods, in order to alter yeast traits for either r...

Glutathione levels influence chronological life span of Saccharomyces cerevisiae in a glucose ‐dependent manner
Abstract
Diet plays a key role in determining the longevity of the organisms since it has been demonstrated that glucose restriction increases lifespan whereas a high‐glucose diet decreases it. However, the molecular basis of how diet leads to the aging process is currently unknown. We propose that the quantity of glucose that fuels respiration influences ROS generation and glutathione levels, and both chemical species impact in the aging process. Herein, we provide evidence that mutation of the gene GSH1 in S. cerevisiae diminishes glutathione levels. Moreover, glutathione levels were higher with 0.5% than in 10% glucos...

On the origins and industrial applications of Saccharomyces cerevisiae × Saccharomyces kudriavzevii hybrids
Abstract
Companies based on alcoholic fermentation products, such as wine, beer and biofuels, use yeasts to make their products. Each industrial process utilizes different media conditions, which differ in sugar content, the presence of inhibitors and fermentation temperature. Saccharomyces cerevisiae has traditionally been the main yeast responsible for most fermentation processes. However, the market is changing due to consumer demand and external factors such as climate change. Some processes, such as biofuel production or winemaking, require new yeasts to solve specific challenges, especially those associated with sust...
