Abstract

Four yeast strains isolated from the nectar of flowers in Pune, India, represent a novel asexual ascomycetous species in the genus . Phylogenetic analyses of the internal transcribed spacer and D1/D2 regions of the LSU rRNA gene place this species within a subclade of large-spored species that includes , and . The new species differs by its ability to grow at 35 °C. Whole-genome sequencing and comparative analyses revealed average nucleotide identity values of 76-77% and digital DNA-DNA hybridization values of 14-16% relative to related species, confirming its novelty. The species is described as sp. nov., with strain MCC 10123 as the ex-type strain and MCC 9961, MCC 9962 and MCC 9928 as additional cultures. The MycoBank number is MB 858027.

摘要

从印度浦那的花蜜中分离出的四株酵母菌株代表了该属中的一个新的无性子囊菌物种。对LSU rRNA基因的内部转录间隔区和D1/D2区域进行系统发育分析，将该物种置于包括、和在内的大孢子物种的一个亚分支中。新物种的不同之处在于其在35°C下生长的能力。全基因组测序和比较分析显示，相对于相关物种，其平均核苷酸同一性值为76-77%，数字DNA-DNA杂交值为14-16%，证实了其新颖性。该物种被描述为新种，菌株MCC 10123为模式菌株，MCC 9961、MCC 9962和MCC 9928为其他培养物。MycoBank编号为MB 858027。
