From genotype to phenotype with 1,086 near telomere-to-telomere yeast genomes - Nature
A newly compiled atlas of species-wide structural variants and gene-based and graph pangenomes derived from highly complete assemblies of genomes from 1,086 natural isolates enable integrative genome-scale studies of Saccharomyces cerevisiae.
