Sequences of two internal transcribed spacer regions between 18S and 28S rRNA for recently described yeasts species, Saccharomyces kunashirensis, S. martiniae, S. rosinii, and S. transvaalensis, were determined to assess their phylogenetic relationship to the other Saccharomyces species. In the two phylogenetic trees constructed by the neighbor-joining method, independent branches reflected that delimitation of the four new species was valid.
为了评估最近描述的酵母物种库纳希尔酵母(Saccharomyces kunashirensis)、马丁酵母(S. martiniae)、罗西尼酵母(S. rosinii)和德兰士瓦酵母(S. transvaalensis)与其他酿酒酵母物种的系统发育关系,测定了18S和28S rRNA之间两个内转录间隔区的序列。在通过邻接法构建的两个系统发育树中,独立的分支表明这四个新物种的界定是有效的。
