Abstract

Saussurea is one of the largest and most rapidly evolving genera within the Asteraceae, comprising approximately 520 species from the Northern Hemisphere. A comprehensive infrageneric classification, supported by robust phylogenetic trees and corroborated by morphological and other data, has not yet been published. For the first time, we recovered a well-resolved nuclear phylogeny of Saussurea consisting of four main clades, which was also supported by morphological data. Our analyses show that ancient hybridization is the most likely source of deep cytoplasmic-nuclear conflict in Saussurea, and a phylogeny based on nuclear data is more suitable than one based on chloroplast data for exploring the infrageneric classification of Saussurea. Based on the nuclear phylogeny obtained and morphological characters, we proposed a revised infrageneric taxonomy of Saussurea, which includes four subgenera and 13 sections. Specifically, 1) S. sect. Cincta, S. sect. Gymnocline, S. sect. Lagurostemon, and S. sect. Strictae were moved from S. subg. Saussurea to S. subg. Amphilaena, 2) S. sect. Pseudoeriocoryne was moved from S. subg. Eriocoryne to S. subg. Amphilaena, and 3) S. sect. Laguranthera was moved from S. subg. Saussurea to S. subg. Theodorea.

基于杂交捕获系统基因组学(Hyb-Seq)的雪莲属植物系统发育和内种分类新见解。
雪莲属是菊科中最大和进化最快的属之一,包括来自北半球的约520种。一个全面的非谱系分类,由健全的系统发育树支持,并由形态学和其他数据证实,尚未发表。首次恢复了由四个主枝组成的雪莲属植物核系统发育,并得到了形态学数据的支持。我们的分析表明,古代杂交是雪莲深层细胞质-核冲突最可能的来源,基于核数据的系统发育比基于叶绿体数据的系统发育更适合于探索雪莲的内属分类。根据获得的雪莲属植物核系统发育特征和形态特征,提出了一种新的雪莲属亚属分类,包括4个亚属13个科。具体来说,1)从紫杉树subg中移出了紫杉树组cinta, Gymnocline, Lagurostemon和Strictae组。雪莲到雪莲。Amphilaena, 2) . Pseudoeriocoryne从s.a。内旋到s subg。3) Laguranthera是从s.s subg转移过来的。雪莲到雪莲。Theodorea。

期刊介绍: Plant Diversity (formerly Plant Diversity and Resources) is an international plant science journal that publishes substantial original research and review papers that advance our understanding of the past and current distribution of plants, contribute to the development of more phylogenetically accurate taxonomic classifications, present new findings on or insights into evolutionary processes and mechanisms that are of interest to the community of plant systematic and evolutionary biologists. While the focus of the journal is on biodiversity, ecology and evolution of East Asian flora, it is not limited to these topics. Applied evolutionary issues, such as climate change and conservation biology, are welcome, especially if they address conceptual problems. Theoretical papers are equally welcome. Preference is given to concise, clearly written papers focusing on precisely framed questions or hypotheses. Papers that are purely descriptive have a low chance of acceptance. Fields covered by the journal include: plant systematics and taxonomy- evolutionary developmental biology- reproductive biology- phylo- and biogeography- evolutionary ecology- population biology- conservation biology- palaeobotany- molecular evolution- comparative and evolutionary genomics- physiology- biochemistry
