Adaptation to complex environments is associated with higher fitness costs under benign conditions

This study shows that adaptation to complex environments with multiple stressors leads to lower fitness gains and higher fitness reductions under benign conditions compared to single stressors.

Lactic acid bacterium F. sanfranciscensis impairs fitness of yeast M. humilis in a synthetic wheat sourdough medium

This study investigates the interaction between yeast M. humilis and bacterium F. sanfranciscensis in sourdough, finding that F. sanfranciscensis impairs M. humilis fitness and suggests a neutral or competitive relationship.

Genotypic and phenotypic diversity of Maudiozyma humilis: the multiple evolutionary trajectories of a domesticated yeast

This study analyzes the genomic and phenotypic diversity of Maudiozyma humilis strains, revealing clonal reproduction, hybridization, and ploidy variation as key factors in its evolutionary history and phenotypic traits.

Evidence for two main domestication trajectories in Saccharomyces cerevisiae linked to distinct bread-making processes

This study identifies two distinct domestication trajectories in Saccharomyces cerevisiae linked to industrial and sourdough bread-making processes, revealing autotetraploidisation as a driver of divergence.
