摘要

担子菌主要是由木耳菌、黑穗病菌、黑穗病菌和锈病菌等形成蘑菇或植物的病原菌组成的。然而,担子菌的所有三个亚门,即Agaricomycotina、puccinomycotina和Ustilaginomycotina,都含有完全或大部分在单细胞阶段生长的物种,这些物种被称为担子菌酵母。然而,这些担子菌酵母的分类在很大程度上独立于其他分类群,主要基于生理生长特征、细胞壁的生化特征,以及DNA特征,如DNA的鸟嘌呤和胞嘧啶的摩尔百分比,以及分子系统发育推断。丝状和蕈状担子菌的分类主要基于形态学。然而,在分子系统学和比较基因组学时代,担子菌科这两个“类群”的分类可以统一起来。在这本真菌学研究中,我们介绍了主要来自担子菌酵母分类群的多个基因的系统发育,我们将这些基因与来自丝状生长担子菌的系统发育信息整合在一起,主要是核糖体DNA大亚基D1D2结构域的序列信息。因此,许多所谓的酵母或酵母样物种可以与丝状生长物种联系起来,并相应地提出了一种更新的分类方法。几个传统上公认的担子菌酵母属是高度多系的,例如隐球菌和红酵母,仅举两例。多基因系统发生使得在很大程度上重新定义这种多基因属成为可能。以一元性为主导原则,采用聚类优化和改进的通用混合Yule聚结(GMYC)迭代应用作为操作

Multigene phylogeny and reclassification of yeasts and related filamentous taxa in Basidiomycota Basidiomycota are mainly known from mushroom-forming or plant pathogenic species, such as the agarics, smuts, bunts and rusts. However, all three subphyla of Basidiomycota, namely Agaricomycotina, Pucciniomycotina and Ustilaginomycotina, contain species that entirely or largely grow in a unicellular stage and that are known as basidiomycetous yeasts. The taxonomy of these basidiomycetous yeasts, however, has developed largely independent from that of the other taxa and was mainly based on physiological growth profiles, biochemical features of the cell wall, but also DNA features, such as molar percentage guanine and cytosine of the DNA, and molecular phylogenetic inferences. The taxonomy of the filamentous and mushroom-forming Basidiomycota was mainly based on morphology. However, in the era of molecular systematics and comparative genomics the taxonomies of these two “groups” of Basidiomycota can be unified. In this volume of Studies in Mycology we present phylogenies using multiple genes mainly of yeast taxa of Basidiomycota that we integrated with phylogenetic information from filamentous growing basidiomycetes, mainly sequence information of the D1D2 domains of the large subunit of the ribosomal DNA. As a result many so-called yeast or yeast-like species could be linked to filamentous growing species and an updated taxonomy is proposed accordingly. Several traditionally recognized genera of basidiomycetous yeasts were highly polyphyletic, e.g. Cryptococcus and Rhodotorula, just to name two. The multigene phylogenies made it possible to a large extent to redefine such polyphyletic genera.

期刊介绍: Restaurator is the only international periodical specializing exclusively in the conservation of library and archive materials. Articles examine the many important aspects of this subject area, such as technology, practical experience and organization. They also focus on scientific basics: Many articles deal with the development of new preservation techniques and the improvement and better understanding of established methods. The articles are written in English with summaries in English, French and German. By reading Restaurator regularly, librarians, archivists and restorers can keep up to date with the latest research and developments. The editorial committee is made up of experts from well-known institutions and organizations from all over the world
