Abstract

Abstract Noccaea Moench is taxonomically one of the most problematic genera of the Brassicaceae. The radical revision of Thlaspi L. s.l. by Meyer in 1973 (Meyer, 1973) split it into 12 segregate genera, including Noccaea, but subsequent molecular studies suggested that this complex includes at least four unrelated genera (Thlaspi s. str., Mummenhoffia Esmailbegi & Al-Shehbaz, Noccidium F. K. Mey., and Noccaea). Although several taxonomic treatments have since been proposed to sort out the systematic problems of Noccaea, debates are still ongoing. Some authors have argued that all segregates of Thlaspi should be considered as independent but related genera, whereas others recognize them as synonyms of a large and polymorphic Noccaea. In this study, we present the first extensively sampled phylogenetic analysis of tribe Coluteocarpeae (Thlaspi segregates including Noccaea) using internal transcribed spacer (ITS) DNA sequences from 92 of the ca. 130 species (70%) in the tribe (39 studied here for the first time) and plastidic trnL-F regions from 73 species (42 studied here for the first time), representing the full range of morphological variation and geographical distribution. All main clades are discussed in detail, and the taxonomic status of all Thlaspi s.l. segregates is evaluated against recent taxonomic treatments. In particular, the tribal placement of Noccidium is changed to Coluteocarpeae, and the genus Pseudosempervivum (Boiss.) Grossh. is reduced to synonymy of Noccaea. The new name N. mummenhoffiana Özüdoğru & Al-Shehbaz and the new combinations N. aucheri (Boiss.) Özüdoğru & Al-Shehbaz and N. sempervivum (Boiss. & Balansa) Özüdoğru & Al-Shehbaz are proposed.

Noccaea属（十字花科）的系统发育及其属外环境的评述1，2

摘要Noccaea Moench在分类学上是十字花科中最有问题的属之一。Meyer在1973年对Thlaspi L.s.L.进行了彻底的修订（Meyer，1973），将其分为12个分离属，包括Noccaea，但随后的分子研究表明，该复合体至少包括四个不相关的属（Thlaspi s.str.，Mummenhofia Esmailbegi&Al Shehbaz，Noccidium F.K.Mey.和Noccaea）。尽管已经提出了几种分类处理方法来解决Noccaea的系统问题，但争论仍在继续。一些作者认为，Thlaspi的所有分离株都应该被视为独立但相关的属，而另一些作者则认为它们是大型多态Noccaea的同义词。在这项研究中，我们首次使用来自92个ca的内部转录间隔区（ITS）DNA序列对Coluteocarpae部落（Thlaspi分离物，包括Noccaea）进行了广泛采样的系统发育分析。部落中的130个物种（70%）（39个在这里首次研究）和73个物种（42个在这里第一次研究）的可塑性trnL-F区域，代表了形态变异和地理分布的全方位。详细讨论了所有主要的分支，并根据最近的分类处理评估了所有Thlaspi s.l.分离株的分类地位。特别是，Noccidium的部落位置被改为Coluteocarpeae和Pseudosempervivum（Boiss.）Grosh属。被简化为Noccaea的同义词。提出了新名称N.mummenhofianaÖzüdoğru和Al Shehbaz，以及新组合N.aucheri（Boiss.）Özúdoğ的ru和Al Shehbaz和N.sempervivum（Boiss.&Balansa）Ö。

期刊介绍： The Annals of the Missouri Botanical Garden is a quarterly international journal primarily devoted to systematic botany and evolutionary biology. We encourage submissions of original papers dealing with significant advances in the taxonomy, phylogeny, biogeography, paleobiology, and evolution of plants, and in conservation genetics and biology, restoration ecology, and ethnobiology, using morphological and/or molecular characters, field observations, and/or database information. We also welcome reviews and papers on conceptual issues and new methodologies in systematics. Important floristic works will also be considered. Symposium proceedings discussing a broader range of topical biological subjects are also published, typically once a year. All manuscripts are peer-reviewed by qualified and independent reviewers.
