Abstract

Abstract: The wild yeast Saccharomyces paradoxus has become a new model in ecology and evolutionary biology. Different lineages of S. paradoxus have been recognized across the world, but the distribution and genetic diversity of the species remain unknown in China, where the origin of its sibling species S. cerevisiae lies. In this study, we investigated the ecological and geographic distribution of S. paradoxus through an extensive field survey in China and performed population genomic analysis on a set of S. paradoxus strains, including 27 strains, representing different geographic and ecological origins within China, and 59 strains representing all the known lineages of the species recognized in the other regions of the world so far. We found two distinct lineages of S. paradoxus in China. The majority of the Chinese strains studied belong to the Far East lineage, and six strains belong to a novel highly diverged lineage. The distribution of these two lineages overlaps ecologically and geographically in temperate to subtropical climate zones in China. With the addition of the new China lineage, the Eurasian population of S. paradoxus exhibits higher genetic diversity than the American population. We observed more possible lineage‐specific introgression events from the Eurasian lineages than from the American lineages. Our results expand the knowledge on ecology, genetic diversity, biogeography, and evolution of S. paradoxus . Take away: S. paradoxus is distributed in temperate to subtropical climate zones in China. A novel highly diverged ancient lineage of S. paradoxus is identified. S. paradoxus exhibits higher genetic diversity in Eurasia than in America. Abstract : Saccharomyces paradoxus is distributed in temperate to subtropical climate zones in China. Chinese S. paradoxus strains cluster with the Far East lineage and a novel highly diverged lineage. The Eurasian population of S. paradoxus exhibits higher genetic diversity and more possible HGT/introgression events than the American population.
