The paper identifies a novel mechanism for autopolyploidization in yeast called SEM, demonstrating triploid and tetraploid formation through postmeiotic endoreplication and mating.

The paper shows repeated loss of mating-type switching in yeast led to heterothallism, polyploidy, and increased heterozygosity across diverse environments.

The paper measures mutation rates in yeast colonies and finds that double mutations occur at higher rates than expected, suggesting transient mutator phenotypes contribute to genomic instability.

This paper presents 142 high-quality yeast genomes to improve pangenome understanding, identifying structural variants and complex genomic regions.

This paper introduces a CRISPR/Cas9 method to generate precise, markerless translocations in yeast, enabling the study of chromosomal rearrangements' phenotypic effects independent of base substitutions.
