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

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 Zygosaccharomyces progenitor</i> sp. nov. (PYCC 7198<sup>T</sup>) and was found in association with bees (<i>Apis mellifera</i> and <i>Bombus</i> spp.) and their honey, besides being found in plants and soil. The novel species belongs to a <i>Zygosaccharomyces</i> subclade that also harbours <i>Zygosaccharomyces rouxii</i>. Although the two species can be differentiated at the sequence level, they cannot be distinguished at the phenotypic level. As is typical of the genus, <i>Z. progenitor</i> sp. nov. produces spherical ascospores after cell conjugation.

Abstract

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 Zygosaccharomyces progenitor</i> sp. nov. (PYCC 7198<sup>T</sup>) and was found in association with bees (<i>Apis mellifera</i> and <i>Bombus</i> spp.) and their honey, besides being found in plants and soil. The novel species belongs to a <i>Zygosaccharomyces</i> subclade that also harbours <i>Zygosaccharomyces rouxii</i>. Although the two species can be differentiated at the sequence level, they cannot be distinguished at the phenotypic level. As is typical of the genus, <i>Z. progenitor</i> sp. nov. produces spherical ascospores after cell conjugation.
