TL;DR: Rather than one or two domestication events leading to the extant baker’s yeasts, the population structure of S. cerevisiae consists of a few well-defined, geographically isolated lineages and many different mosaics of these lineages, supporting the idea that human influence provided the opportunity for cross-breeding and production of new combinations of pre-existing variations.

TL;DR: Rather than one or two domestication events leading to the extant baker's yeasts, the population structure of S. cerevisiae shows a few well defined geographically isolated lineages and many different mosaics of these lineages, supporting the notion that human influence provided the opportunity for outbreeding and production of new combinations of pre-existing variation.
Journal ArticleDOI
Chromosomal evolution in Saccharomyces
TL;DR: It is shown that rearrangements have occurred between closely related species, whereas more distant ones have colinear genomes, and that the rate of formation of translocations is not constant.
Journal ArticleDOI
Three new species in the Saccharomyces sensu stricto complex: Saccharomyces cariocanus, Saccharomyces kudriavzevii and Saccharomyces mikatae.
TL;DR: Genetic and molecular analyses did not confirm the previously observed conspecificity of Saccharomyces paradoxus and S. cariocanus, but three new SacCharomyces species are described.
Journal ArticleDOI
Use of an rRNA internal transcribed spacer region to distinguish phylogenetically closely related species of the genera Zygosaccharomyces and Torulaspora.
TL;DR: It is revealed that members of the yeast genera Torulaspora and Zygosaccharomyces are phylogenetically intermixed and it is possible to identify conserved regions in both ITSs that are useful in species differentiation.
