Abstract

Two yeast strains, designated NYNU 22992 and NYNU 229246, were obtained from the phylloplane of and in the Guiyang Medicinal Botanical Garden, Guizhou, China. Phylogenetic evaluation, incorporating concatenated ITS and D1/D2 LSU sequences, indicated a close relationship between these isolates and , , and . Sequence identity comparisons showed similarity levels of 99.7-98.2% for D1/D2 LSU and 96.8-94% for the ITS region. Minor physiological traits were noted, as these strains were unable to utilize xylitol, differentiating them from , and . Physiological data for were not available for comparison. Based on both phylogenetic positioning and phenotypic characteristics, these yeast strains represent a novel species within , for which the name sp. nov. is proposed with holotype GDMCC 2.322 (MycoBank MB 858491).

摘要

从中国贵州贵阳药用植物园的和的叶表面获得了两株酵母菌株，分别命名为NYNU 22992和NYNU 229246。结合ITS和D1/D2 LSU串联序列的系统发育评估表明，这些分离株与、、和关系密切。序列同一性比较显示，D1/D2 LSU的相似性水平为99.7 - 98.2%，ITS区域的相似性水平为96.8 - 94%。注意到这些菌株的一些次要生理特征，因为它们不能利用木糖醇，这使它们与、和区分开来。没有的生理数据可供比较。基于系统发育定位和表型特征，这些酵母菌株代表了属内的一个新物种，为此提出新名称 sp. nov.，模式菌株为GDMCC 2.322（MycoBank MB 858491）。
