The Saccharomyces sp. CID1 isolate (CBS 8614) and several other Saccharomyces sensu stricto yeasts were analysed for their mitochondrial and nuclear genes. The data show that Saccharomyces sp. CID1, found so far only in one location in Europe, is a natural hybrid between three different Saccharomyces yeast species. Two of them, Saccharomyces cerevisiae-like and Saccharomyces bayanus-like, are ubiquitous and contributed parts of the nuclear genome; the third, Saccharomyces sp. IFO 1802-like, which has been found only in Japan, contributed the mitochondrial DNA molecule. These data suggest that the yeast cell is able to accommodate, express and propagate genetic material that originates from different species, and the very existence of the resulting natural hybrids indicates that such hybrids are well adapted to their habitats.
对酿酒酵母属CID1分离株（CBS 8614）和其他几种狭义酿酒酵母进行了线粒体和核基因分析。数据表明，迄今仅在欧洲一个地点发现的酿酒酵母属CID1是三种不同酿酒酵母物种之间的天然杂交种。其中两种，类似酿酒酵母和类似贝酵母，广泛存在并贡献了核基因组的部分；第三种，仅在日本发现的类似IFO 1802酿酒酵母，贡献了线粒体DNA分子。这些数据表明，酵母细胞能够容纳、表达和繁殖源自不同物种的遗传物质，而由此产生的天然杂交种的存在表明这些杂交种很好地适应了它们的栖息地。
