Abstract:

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.
