Expanding the geographical distribution of Blastobotrys malaysiensis (Saccharomycetales) beyond the Asian continent – a cave fungus first reported in the Americas

Saccharomycetales are ascomycetic yeasts and, amongst them, the genus Blastobotrys has approximately 30 known species. Blastobotrys malaysiensis is a yeast species, described from cave samples, known until then only from Malaysia. In this study, we characterise a new strain and report the second occurrence record of this species. Here, Blastobotrys malaysiensis URM 8507/SXS 675, was collected from sediments samples from a cave in the Parque Estadual de Terra Ronca (PETER) in Goiás, Brazil. Phylogenetic analyses revealed strong support with the sequence of the species type, as well as with other species of the clade. This new record contributes by providing new molecular data for the species and expanding the knowledge of its distribution beyond the Asian continent.First record of a yeast for the American continent and its second mention for the world.

子囊菌纲中的酵母菌类中， Blastobotrys 属拥有约30个已知物种。Blastobotrys malaysiensis 作为一种酵母菌，源于洞穴样本，此前仅知其产于马来西亚。本研究中，我们对该属的一种新菌株进行了描述，并报告了该物种的第二例出现记录。具体而言，Blastobotrys malaysiensis URM 8507/SXS 675 株是从巴西戈亚斯的 Parque Estadual de Terra Ronca（PETER）洞穴的沉积物样本中采集而来。系统发育分析显示，该菌株与物种模式序列及其他属群中的物种序列具有高度支持性。这一新记录通过提供该物种的新分子数据，丰富了其分布知识，并超越了亚洲大陆。此为美洲大陆首次发现酵母菌，亦是全球对该物种的第二次提及。
