In the macroscopic world, ecological interactions between multiple species of fauna and flora are recognised as major role-players in the evolution of any particular species. By comparison, research on ecological interactions as a driver of evolutionary adaptation in microbial ecosystems has been neglected. The evolutionary history of the budding yeast Saccharomyces cerevisiae has been extensively researched, providing an unmatched foundation for exploring adaptive evolution of microorganisms. However, in most studies, the habitat is only defined by physical and chemical parameters, and little attention is paid to the impact of cohabiting species. Such ecological interactions arguably provide a more relevant evolutionary framework. Within the genomic phylogenetic tree of S. cerevisiae strains, wine associated isolates form a distinct clade, also matched by phenotypic evidence. This domestication signature in genomes and phenomes suggests that the wine fermentation environment is of significant evolutionary relevance. Data also show that the microbiological composition of wine fermentation ecosystems is dominated by the same species globally, suggesting that these species have co-evolved within this ecosystem. This system therefore presents an excellent model for investigating the origins and mechanisms of interspecific yeast interactions. This review explores the role of biotic stress in the adaptive evolution of wine yeast.

对等压力:葡萄酒酵母中对生物压力的进化反应。

在宏观世界中,动植物的多种物种之间的生态相互作用被认为是任何特定物种进化的主要角色。相比之下,人们忽略了生态相互作用作为微生物生态系统进化适应的驱动力的研究。芽孢酵母啤酒酵母的进化历史已被广泛研究,为探索微生物的适应性进化提供了无与伦比的基础。但是,在大多数研究中,生境仅由物理和化学参数定义,很少关注同居物种的影响。这种生态相互作用可以说提供了更相关的进化框架。在酿酒酵母菌株的基因组系统树中,与葡萄酒相关的分离株形成独特的进化枝,也有表型证据匹配。这种在基因组和现象组中的驯化特征表明,葡萄酒发酵环境具有重要的进化意义。数据还显示,葡萄酒发酵生态系统的微生物组成在全球范围内受同一物种的支配,这表明这些物种在该生态系统内共同进化。因此,该系统为研究种间酵母相互作用的起源和机理提供了一个极好的模型。这篇综述探讨了生物应激在葡萄酒酵母适应性进化中的作用。数据还显示,葡萄酒发酵生态系统的微生物组成在全球范围内受同一物种的支配,这表明这些物种在该生态系统内共同进化。因此,该系统为研究种间酵母相互作用的起源和机理提供了一个极好的模型。这篇综述探讨了生物应激在葡萄酒酵母适应性进化中的作用。数据还显示,葡萄酒发酵生态系统的微生物组成在全球范围内受同一物种的支配,这表明这些物种在该生态系统内共同进化。因此,该系统为研究种间酵母相互作用的起源和机理提供了一个极好的模型。这篇综述探讨了生物应激在葡萄酒酵母适应性进化中的作用。
