Phylogenetic relationships of species assigned to the genus Metschnikowia were estimated from the extents of divergence among partial sequences of rRNA. The data suggest that the aquatic species (Metschnikowia australis, Metschnikowia bicuspidata, Metschnikowia krissii, and Metschnikowia zobellii) and the terrestrial species (Metschnikowia hawaiiensis, Metschnikowia lunata, Metschnikowia pulcherrima, and Metschnikowia reukaufii) form two groups within the genus. M. lunata and M. hawaiiensis are well separated from other members of the genus, and M. hawaiiensis may be sufficiently divergent that it could be placed in a new genus. Species of the genus Metschnikowia are unique compared with other ascomycetous yeasts because they have a deletion in the large-subunit rRNA sequence that includes nucleotides 434 to 483.
基于rRNA部分序列的差异程度，对归入梅奇酵母属（Metschnikowia）的物种进行了系统发育关系估计。数据表明，该属内的水生物种（澳大利亚梅奇酵母、双尖梅奇酵母、克里西梅奇酵母和佐贝尔梅奇酵母）和陆生物种（夏威夷梅奇酵母、新月形梅奇酵母、美丽梅奇酵母和鲁考夫梅奇酵母）形成了两个类群。新月形梅奇酵母和夏威夷梅奇酵母与该属的其他成员有明显区分，并且夏威夷梅奇酵母的差异可能足够大，以至于可以将其归入一个新属。与其他子囊菌酵母相比，梅奇酵母属的物种具有独特性，因为它们在大亚基rRNA序列中存在一个缺失，该缺失包含核苷酸434至483。
