Abstract

Pantropical regions possess the highest biodiversity on earth yet detailed systematic studies involving pantropical genera often pose significant challenges due to the extensive need for intercontinental sampling. Zanthoxylum, a genus comprising 225 species within the family Rutaceae, provides an excellent model for such studies due to its distribution on most continents and tropical archipelagos. Despite the genus' economic significance, no phylogenetic study with a comprehensive taxon sampling has been conducted. Previous research using Sanger sequencing failed to resolve key questions regarding the genus. To resolve these questions, this study employs the hybrid capture method to: (1) conduct a comprehensive phylogenetic analysis of Zanthoxylum; (2) evaluate Engler's and Reynel's sectional classifications; (3) explore the evolution of the homochlamydeous flower character in section Zanthoxylum; (4) test the monophyly of several species, particularly those with a wide distribution; and (5) to assess hybridization and incomplete lineage sorting in Zanthoxylum. Our analyses resolved Zanthoxylum as monophyletic with four clades centred on different biogeographical regions. Sections Tobinia, Pterota and Zanthoxylum are monophyletic and section Blackburnia and section Macqueria each proved to be polyphyletic. Zanthoxylum s.str. is only monophyletic if Z. clava-herculis and Z. nitidum with heterochlamydeous flowers are placed in it. The separation of Zanthoxylum s.str. into section Sinensis and section Zanthoxylum is not supported. Section Macqueria is highly polyphyletic and spread across three main clades, while section Pterota and section Tobinia are each monophyletic. The widespread Z. asiaticum sampled throughout its distribution from Madagascar and tropical Africa to tropical Asia was found to be monophyletic, representing its own isolated clade within Zanthoxylum. A sectional classification synopsis for Zanthoxylum is provided except that future taxonomic work for section Macqueria is necessary. Quartet sampling suggests incomplete lineage sorting and hybridization within Zanthoxylum.

物种丰富的泛热带花椒属(芸香科)的杂交捕获系统发育。
泛热带地区拥有地球上最高的生物多样性,但由于广泛需要洲际采样,涉及泛热带属的详细系统研究往往面临重大挑战。花椒属(Zanthoxylum)是芸香科(rutacae)中一个由225种组成的属,由于其分布在大多数大陆和热带群岛,因此为此类研究提供了一个极好的模型。尽管该属具有经济意义,但尚未进行全面的分类群抽样系统发育研究。先前使用Sanger测序的研究未能解决有关该属的关键问题。为了解决这些问题,本研究采用杂交捕获方法:(1)对花椒属植物进行全面的系统发育分析;(2)评价Engler和Reynel的分段分类;(3)探讨花椒科同衣原体花性状的演化;(4)检验若干种的单系性,特别是那些分布广泛的种;(5)评价花椒属植物的杂交和不完全谱系分选。我们的分析表明花椒属是单系的,有四个分支集中在不同的生物地理区域。Tobinia、Pterota和Zanthoxylum是单系植物,Blackburnia和Macqueria是多系植物。花椒属植物s.str。如果将异衣原体花的竹属植物和竹属植物置于其中,则为单系植物。花椒属植物的分离。不支持分为Sinensis和Zanthoxylum两个部分。maceria组是高度多系的,分布在三个主要分支上,而Pterota组和Tobinia组都是单系的。在从马达加斯加和热带非洲到热带亚洲的分布中广泛取样的亚洲Z. asiaticum被发现是单系的,代表了花椒门中自己的孤立分支。本文提供了花椒科的剖面分类概要,但对麦凯里亚剖面的分类工作仍有必要。四重奏取样表明花椒属的谱系分类和杂交不完全。

期刊介绍: Molecular Phylogenetics and Evolution is dedicated to bringing Darwin''s dream within grasp - to "have fairly true genealogical trees of each great kingdom of Nature." The journal provides a forum for molecular studies that advance our understanding of phylogeny and evolution, further the development of phylogenetically more accurate taxonomic classifications, and ultimately bring a unified classification for all the ramifying lines of life. Phylogeographic studies will be considered for publication if they offer EXCEPTIONAL theoretical or empirical advances.
