由于其在食品和饮料发酵中的长期全球使用历史，酵母菌是人类文明的重要组成部分。然而，驯化的酵母种群的多样性和进化历史仍然难以捉摸。我们在这里表明，中国/远东亚洲可能是该物种驯化种群的起源中心。驯化的人群形成两个主要群体与固态和液态发酵，似乎起源于杂合祖先，这可能是由不同的野生菌株之间的异交形成的，以适应麦芽糖丰富的生态位。我们在整个驯化种群中发现了一致的基因扩增和收缩，以及导致适应不同环境的谱系特异性基因组变异。我们展示了S的多样性和生活史的几乎全景。对物种的起源和进化提供了新的见解。
The yeastSaccharomyces cerevisiaehas been an essential component of human civilization because of its long global history of use in food and beverage fermentation. However, the diversity and evolutionary history of the domesticated populations of the yeast remain elusive. We show here that China/Far East Asia is likely the center of origin of the domesticated populations of the species. The domesticated populations form two major groups associated with solid- and liquid-state fermentation and appear to have originated from heterozygous ancestors, which were likely formed by outcrossing between diverse wild isolates primitively for adaptation to maltose-rich niches. We found consistent gene expansion and contraction in the whole domesticated population, as well as lineage-specific genome variations leading to adaptation to different environments. We show a nearly panoramic view of the diversity and life history ofS. cerevisiaeand provide new insights into the origin and evolution of the species.
