Abstract：
Four yeast isolates collected from flowers from different ecosystems in Brazil, one from fruit of Nothofagus alpina in Argentina, three from flowers of Neltuma chilensis in Chile and one obtained from the proventriculus of a female bumblebee in Canada were demonstred, by analysis of the sequences of the internal transcribed spacer (ITS) region and D1/D2 domains of the large subunit rRNA gene, to represent two novel species of the genus Starmerella. These species are described here as Starmerella gilliamiae f.a, sp. nov. (CBS 16166T; Mycobank MB 851206) and Starmerella monicapupoae f.a., sp. nov. (PYCC 8997T; Mycobank MB 851207). The results of a phylogenomic analysis using 1037 single-copy orthogroups indicated that S. gilliamiae is a member of a subclade that contains Starmerella opuntiae, Starmerella aceti and Starmerella apicola. The results also indicated that S. monicapupoae is phylogenetically related to Starmerella riodocensis. The two isolates of S. monicapupoae were obtained from flowers in Brazil and were probably vectored by insects that visit these substrates. Starmerella gilliamiae has a wide geographical distribution having been isolated in flowers from Brazil and Chile, fruit from Argentina and a bumblebee from Canada.
摘要：
从巴西不同生态系统的花朵中收集的四种酵母分离物，一个来自阿根廷Nothofagusalpina的水果，三个来自智利Neltumachilensis的花和一个从加拿大雌性大黄蜂的proventricus获得的花被妖魔化了，通过分析大亚基rRNA基因的内部转录间隔区（ITS）区域和D1/D2结构域的序列，代表Starmerella属的两个新物种。这些物种在这里被描述为Starmerellagilliamiaef.a，sp.11月。（CBS16166T；MycobankMB851206）和Starmerellamonicapupoaef.a.，sp.11月。（PYCC8997T；MycobankMB851207）。使用1037个单拷贝正统组进行的系统基因组分析结果表明，吉兰氏链球菌是包含Starmerellaopuntiae的亚进化枝的成员，醋酸星藻和apicola星藻。结果还表明，沙棘与星藻在系统发育上有关。S.monicapupoae的两个分离株是从巴西的花朵中获得的，并且可能被访问这些底物的昆虫所传播。Gilliamiae的地理分布很广，在巴西和智利的花朵中被分离出来，来自阿根廷的水果和来自加拿大的大黄蜂。
