Molecular data (nrITS‐sequencing) reveal relationships among Iranian endemic taxa of the Umbelliferae

Abstract

The majority of endemic and subendemic Iranian Umbelliferae taxa have never been investigated using molecular approachs to phylogeny. 36 species from 28 genera of the Umbelliferae from this region were included for the first time in analysis using ITS sequence data to clarify their systematics. For some newly investigated (Leiotulus, Semenovia, Ducrosia, Echinophora, Pycnocycla, Turgenia lisaeoides, Prangos, Alococarpum, Bilacunaria, Elaeosticta, Johreniopsis, Pseudotrachydium) taxa the molecular data correspond to, or at least do not contradict with, their traditional, morphologically grounded taxonomy. Leutea was shown closely related to Ferula (not Peucedanum), and Opsicarpium – to Pimpinella. A taxonomically isolated position of Mozaffariania has been demonstrated. Haussknechtia appeared to be the closest relative of Demavendia and Zeravschania. It was shown that Calyptrosciadium belongs to Komarovia ‐clade, having long‐distant geographical disjunction. Close affinity of Heptaptera and Prangos was not supported. Similarly, Thecocarpus appeared to be distant from other Echinophoreae, putting monophyly of the tribe in question. As a result, new molecular data have cleared up systematic questions in some taxonomically uncertain Iranian Umbelliferae. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Molecular phylogenetics of Pimpinella and allied genera (Apiaceae), with emphasis on Chinese native species, inferred from nrDNA ITS and cpDNA intron sequence data

“…Similarly, the Iranian endemic species Opsicarpium insignis also falls within the Pimpinella ‘core group’. Previously, Valiejo‐Roman et al () reported that Pimpinella and Opsicarpium are close genera based on molecular data, a relationship supported by their similar fruit structure and pinnate leaves. Our results corroborate the inclusion of Opsicarpium into Pimpinella .…”

Phylogenetic relationships among Dorema, Ferula and Leutea (Apiaceae: Scandiceae: Ferulinae) inferred from nrDNA ITS and cpDNA noncoding sequences

“…Their close relationship was confirmed using immunological comparisons of seed-storage proteins (Shneyer & al., 1995). In contrast, the first ITS sequence analyses placed Dorema, represented by a single accession of D. aucheri Boiss., as sister group to Seseli mucronatum (Schrenk) Pimenov & Sdobnina in tribe Selineae distant from Ferula (Valiejo-Roman & al., 2006). This result was probably due to sample contamination or voucher misidentification because subsequent molecular studies confirmed that Dorema is closely related to Ferula (Ajani & al., 2008;Kurzyna-Młynik & al., 2008).…”

Notes on systematics and taxonomy for the Italian vascular flora. 2.

“…This paper is the second contribution in the series regarding the nomenclature of the Italian vascular flora and other phanerogams, following on a preliminary note and an observation on the genus Vachellia (Banfi & Dichoropetalum Based on analyses of the ITS sequences, the genus Holandrea, already recently separated from Peucedanum, has been transferred to Dichoropetalum Fenzl together with other species of Peucedanum s.l., all grouped as belonging to the SE-European-SW-Asiatic chorotype (Valiejo-Roman et al, 2006;Pimenov et al, 2007). The following species are recognised in Italy.…”
