Molecular phylogenetic studies have had major impacts on the delineation of higher-level taxa in many plant groups. Apiaceae subfamily Apioideae, its largest subfamily, is in the process of major systematic rearrangements owing to these studies. Iran, with more than one fourth of all apioid genera, is a biodiversity hotspot for this subfamily, though the sampling of these taxa from this region has been insufficient. Currently, 111 apioid genera are recognized in Iran of which 18 including five endemics are not presented or are under-represented in previous phylogenetic studies. We used the sequences of nuclear ribosomal internal transcribed spacer (ITS) and chloroplast rps16 intron (rps16) regions from 325 and 149 accessions, respectively, representing most of the known genera of Apioideae from Iran. Twenty-nine ITS and 26 rps16 sequences were newly generated for this study. Phylogenetic trees were reconstructed using Bayesian inference, Maximum likelihood, and Maximum parsimony methods. The results assign the endemic genera Ergocarpon to Echinophoreae, Lomatopodium to Selineae, Froriepia and Oliveria to Pyramidoptereae, and Stenotaenia to Tordylieae. In addition, Ormosciadium, morphologically characterized by moniliform and inflated mericarp margins, is assigned to Tordylieae. Neocryptodiscus persicus is shown to be a synonym of Prangos persica. The previous placement of Heptaptera in the Physospermopsis clade is not correct and it should be moved to the Opopanax clade. Morphological characters deemed to be of high diagnostic value are the shape of leaf segments, presence of tubers, colour of petals, and mericarp features including shape, presence of lateral or dorsal wings, and type of compression and indumentum. A diagnostic key to 19 tribes, nine subtribes and other major clades compatible with these taxonomic ranks and an updated list of genera of Apioideae occurring in Iran with their tribal and subtribal position is provided.

伞形科亚科伞形科更新的基于谱系的部落分类,特别关注伊朗属

分子系统发育研究对许多植物群中高级分类群的划分产生了重大影响。由于这些研究,伞形科亚科 Apioideae 是其最大的亚科,正处于主要的系统重排过程中。伊朗拥有超过四分之一的类猿属,是该亚科的生物多样性热点,尽管来自该地区的这些类群的采样不足。目前,伊朗有 111 种类猿属,其中 18 种(包括 5 种地方性)在之前的系统发育研究中没有出现或代表性不足。我们使用了分别来自 325 和 149 个种质的核核糖体内部转录间隔区 (ITS) 和叶绿体 rps16 内含子 (rps16) 区域的序列,代表了伊朗 Apioideae 的大多数已知属。本研究新生成了 29 个 ITS 和 26 个 rps16 序列。使用贝叶斯推理、最大似然和最大简约方法重建系统发育树。结果将地方性属 Ergocarpon 归于 Echinophoreae,Lomatopodium 归于 Selineae,Froriepia 和 Oliveria 归于 Pyramidopteraeae,而 Stenotaenia 归于 Tordylieae。此外,Ormosciadium 的形态特征为念珠状和膨大的分果边缘,属于 Tordylieae。Neocryptodiscus persicus 被证明是 Prangos persica 的同义词。Heptaptera 先前在 Physospermopsis 进化枝中的放置是不正确的,应该将其移至 Opopanax 进化枝。被认为具有高诊断价值的形态特征是叶段的形状、块茎的存在、花瓣的颜色和分果特征,包括形状、侧翼或背翼的存在,以及压缩和毛被的类型。提供了与这些分类等级兼容的 19 个部落、9 个亚部落和其他主要进化枝的诊断关键,以及伊朗发生的 Apioideae 属的更新列表及其部落和亚部落位置。
