薤白 (Allium macrostemon) 是葱属中重要的药食同源种类,其系统地位和分类等级迄今尚无统一定论,一直存有争议。为了探讨其系统位置及其与相关类群的亲缘关系,本研究利用nrDNA ITS和cpDNA trnLF序列数据对该种及若干近缘类群进行了系统发育分析。基于贝叶斯法和最大简约法构建的系统树均表明薤白为一单系种,与多系的组Caerulea、Pallasia的部分种类有密切的系统发育关系,而与组Codonoprasum和Allium的种类关系疏远;结合总苞、花丝和子房等形态学特征,不支持将薤白划归Allium组或置于广义的Scorodon组。薤白可能代表一个新的组一级的类群,但尚待增加类群采样(尤其是中亚的种类)进一步研究。本文还在系统发育框架下探讨了中药薤白(Allii Macrostemonis Bulbus)的基源植物(薤白、藠头、棱叶韭和长梗韭)及Pallasia组部分物种的系统位置。

Allium macrostemon is an important medicinal and edible plant. Its systematic position and taxonmical classification remain controversial to date. To explore this issue, we reconstructed phylogenetic relationships among Amacrostemon and other related taxa using nrDNA ITS and cpDNA trnLF markers. The phylogenetic trees derived from Bayesian inference and maximumparsimony analysis showed that Amacrostemon is monophyletic, and has a close relationship with some species of polyphyletic sections Caerulea and Pallasia instead of sections Codonoprasum and Allium. The including of Amacrostemon within section Allium was not supported by both molecular data and morphological characters of spathe, filaments and ovary. Allium macrostemon should be included in a new section, however further studies using additional samples (especially those from Central Asia) is necessary. In addition, we also provided a discussion on the phylogenetic relationships among four original plants (Amacrostemon, Achinense, Acaeruleum and Aneriniflorum) of Allii Macrostemonis Bulbus and systematic position of partial species of section Pallasia.
