摘要

随着序列数据的可用性,我们对红酵母系统的了解已经大大提高,现在很清楚,这些真菌中的大多数属于三种不同的担子菌门:Agaricostilbomycetes, Cystobasidiomycetes和Microbotryomycetes。尽管在系统发育定位方面有所改进,但这些真菌的分类一直需要修订,并且仍然没有完全解决,部分原因是缺少分类群。在本研究中,我们提供了基于培养的环境酵母分离的数据,揭示了几个未描述的同形孢子菌种,最近被引入以容纳六个物种,这些物种以前被放置在孢子菌属的无性属和红托菌属的囊泡菌属/marina分支。基于三个rDNA位点的分子系统发育分析、形态学和生化研究,我们正式描述了以下新种:来自葡萄牙和美国叶片表面的clarorosea Symmetrospora sp. nov.;pseudomarina sp. 11 .来自巴西和美国的叶片表面和美国的腐烂木材;在美国的甲虫内脏、巴西的叶子表面以及台湾和泰国的海水中发现了苏希氏沙门氏菌。最后,基于我们的分子系统发育数据,我们提出了一个新的水稻芽孢菌组合——对称孢子菌(Symmetrospora oryzicola comb)。11月。

Red yeasts from leaf surfaces and other habitats: three new species and a new combination of <i>Symmetrospora</i> (<i>Pucciniomycotina, Cystobasidiomycetes</i>).

Red yeasts from leaf surfaces and other habitats: three new species and a new combination of <i>Symmetrospora</i> (<i>Pucciniomycotina, Cystobasidiomycetes</i>).

Red yeasts from leaf surfaces and other habitats: three new species and a new combination of Symmetrospora (Pucciniomycotina, Cystobasidiomycetes).

Our understanding of the systematics of red yeasts has greatly improved with the availability of sequence data and it is now clear that the majority of these fungi belong to three different classes of Pucciniomycotina (Basidiomycota): Agaricostilbomycetes, Cystobasidiomycetes, and Microbotryomycetes. Despite improvements in phylogenetic placement, the taxonomy of these fungi has long been in need of revision and still has not been entirely resolved, partly due to missing taxa. In the present study, we present data of culture-based environmental yeast isolation, revealing several undescribed species of Symmetrospora, which was recently introduced to accommodate six species previously placed in the asexual genera Sporobolomyces and Rhodotorula in the gracilis/marina clade of Cystobasidiomycetes. Based on molecular phylogenetic analyses of three rDNA loci, morphology, and biochemical studies, we formally describe the following new species: Symmetrospora clarorosea sp. nov. from leaf surfaces in Portugal and the USA; S. pseudomarina sp. nov. from leaf surfaces in Brazil, and the USA and decaying wood in the USA; and S. suhii sp. nov. from a beetle gut in the USA, leaf surfaces in Brazil and marine water in the Taiwan and Thailand. Finally, we propose a new combination for Sporobolomyces oryzicola based on our molecular phylogenetic data, Symmetrospora oryzicola comb. nov.
