摘要

Onobrychis montana DC.Subsp.transsilvanica（Simonk.）Jáv.（豆科）是喀尔巴阡山脉东南部特有的植物分类群，其分类地位与基于形态特征的经典分类法不一致。在之前的研究中，我们通过对几个叶绿体 DNA 区域进行测序和 AFLP 基因分型，试图澄清其分类地位与更广泛分布的 O. montana DC.之间的争议，并确定其在喀尔巴阡山脉内的系统地理结构。本研究基于 7 个 SSR 标记的 DNA 指纹图谱，通过提高分辨率和对以前确定的系统地理群进行亚聚类，对这一问题分类群有了更深入的了解。然而，新的 SSR 遗传数据与 AFLP 和叶绿体 SNP 揭示的分子证据一致，并不支持 O. montana DC.Subsp.作为与 O. montana DC.

New insights regarding the taxonomy and phylogeography of Onobrychis montana DC. subsp. transsilvanica (Fabaceae)

Onobrychis montana DC. Subsp. transsilvanica (Simonk.) Jáv. (Fabaceae) is a plant taxon, endemic to the South-Eastern Carpathians, whose taxonomic status is treated inconsistently by the classic taxonomy based on morphological traits. In a previous study, by sequencing several chloroplast DNA regions and AFLP genotyping, we tried to elucidate the controversy concerning its taxonomic status in relation to the more widespread O. montana DC., and determined its phylogeographic structure within the Carpathians. The present study, based on DNA fingerprinting by seven SSR markers, brings more insights on this problematic taxon by conferring higher resolution and sub-clustering previously identified phylogeographic groups. However, the newly SSR genetic data are in agreement with molecular evidence revealed by AFLP and chloroplastic SNPs and do not support O. montana DC. Subsp. transsilvanica (Simonk.) Jáv. As a distinct species from O. montana DC.
