Abstract
Statement of the Problem: Saccharomyces cerevisiae is the main driving force of traditional food fermentation; Both geographic differentiation and human activities drive the global evolution of S. cerevisiae, but its domestication origin is keeping unknown as an academic dispute. The Silk Road combined diverse geographical features and diversity civilization is most possible to be pregnant with unique genotypic - phenotypic features of indigenous S. cerevisiae population. Xinjiang in China is an indispensable part of Silk Road.
Methodology & Theoretical Orientation: S. cerevisiae regional characteristic was studied from Xinjiang, China, with the methods of SSR and multiple gene sequencing.
Findings: The diversity of S. cerevisiae associated with grape in Xinjiang was very rich beyond our thoughts; there were tree unique groups different from European wine strains and Chinese S. cerevisiae. The regional relationship of S. cerevisiae population in northern Xinjiang was closer than in southern Xinjiang, the migration direction of S. cerevisiae population was referenced from east to west and from north to south in Xinjiang and was more impacted on by human activity than climates, although both of them were important for the relational characters of indigenous S. cerevisiae populations.
Conclusion & Significance: The relationships of S. cerevisiae population in Xinjiang tested in the study would afford a firm scientific reference to identify the terrio grape or wine and to analyze the evolutionary characters of S. cerevisiae.
