<i>Zygosaccharomyces progenitor</i> sp. nov., a new yeast species associated with bees of the genera <i>Apis</i> and <i>Bombus</i>

A novel ascomycetous yeast species of the genus <i>Zygosaccharomyces </i>is proposed based on isolates obtained in Japan, Portugal and the USA, and on a combination of conventional DNA-barcode sequence analyses and whole-genome phylogenies. The new species is described <i>as Z. progenitor</i> sp. nov. (PYCC 7198^T) and was found in association with bees (<i>Apis mellifera</i> and <i>Bombus</i> spp) and their honey, besides being also found in plants and soil. The novel species belongs to a <i>Zygosaccharomyces</i> subclade that also harbours <i>Z. rouxii</i>. Although the two species can be differentiated at the sequence level, they cannot be distinguished at the phenotypic level. As is typical in the genus, <i>Z. progenitor</i> sp. nov. produces spherical ascospores after cell conjugation.

本研究基于从日本、葡萄牙及美国分离获得的菌株，结合传统DNA条形码序列分析与全基因组系统发育分析，提议建立一个隶属于接合酵母属（Zygosaccharomyces）的新型子囊酵母菌种。该新种被命名为Z. progenitor sp. nov.，模式菌株为PYCC 7198^T，其分离源涵盖与其伴生的蜜蜂（西方蜜蜂（Apis mellifera）与熊蜂属（Bombus）物种）及其蜂蜜，此外还可从植物与土壤中分离得到。该新型菌种隶属于一个同时包含鲁氏接合酵母（Zygosaccharomyces rouxii）的接合酵母属亚分支。尽管二者可通过序列特征加以区分，但无法通过表型特征进行鉴别。正如该属的典型特征，Z. progenitor sp. nov.在细胞接合后会产生球形子囊孢子。
