Abstract

Phylogenetic relationships within the genus Cladonia, including Cladina (Cladoniaceae, Lecanoromycetes), were reconstructed based upon simultaneous analyses of DNA sequences and morphological and chemical data. We used sequences from the internal transcribed spacer 1 (ITS1), the 5.8 rDNA gene, and the internal transcribed spacer 2 (ITS2) of the nuclear rDNA gene cluster, and partial sequences from the protein-coding β-tubulin gene. The analyses included 235 specimens of 168 taxa representing all currently recognized sections of Cladonia and Cladina and the outgroup genera Cladia, Pycnothelia, and Ramalea. Analyses were performed using optimization alignment with three different parameter values. The results of all analyses support the inclusion of Cladina in Cladonia. The current sectional division of Cladonia was not supported, and a new provisional classification for the genus is proposed.

摘要

基于对DNA序列以及形态学和化学数据的同步分析，重建了石蕊属（Cladonia）内部的系统发育关系，其中包括粉石蕊属（Cladina，石蕊科，茶渍纲）。我们使用了核核糖体DNA基因簇的内部转录间隔区1（ITS1）、5.8 rDNA基因和内部转录间隔区2（ITS2）的序列，以及蛋白质编码β-微管蛋白基因的部分序列。分析包括168个分类单元的235个标本，这些标本代表了石蕊属和粉石蕊属目前所有公认的组，以及外类群属克劳迪石蕊属（Cladia）、皮壳衣属（Pycnothelia）和小烛藓属（Ramalea）。使用具有三种不同参数值的优化比对进行分析。所有分析结果都支持将粉石蕊属归入石蕊属。目前对石蕊属的分组划分不成立，因此提出了该属的一个新的临时分类。
