چکیده

The genus Ononis,embraces more than 85 species worldwide. In the present study, materials of two subspecies of O. spinosa from different localities of Iran alongside some other native species of the genus were included in phylogenetic analyses. In addition, over 50 accessions were obtained from GenBank. In order to clarify the exact number of subspecies of O. spinosa in Iran, datasets were obtained from sequencing of nuclear ribosomal ITS (nr DNA ITS) and trnL-F plastid (cp DNA) regions and analysed. Three taxa belonging to O. spinosa L. complex (O. spinosa subsp. leiosperma, O. spinosa subsp. antiquorum, and O. arvensis=O. spinosa subsp. arvensis) were previously reported from Iran. Based on Maximum Parsimony and Bayesian analyses of the molecular datasets, it is shown that, unlike the previous reports, Iranian O. spinosa complex belongs to only two subspecies (i.e. leiosperma and arvensis subspp.). In addition, we also found that, O. spinosa subsp. antiquorum is not present in Iran. It was also demonstrated that, seed sculpturing does not provide valuable characters in diagnosing different subspecies of O. spinosa.

This study represents phylogenetic analyses of two woody polygonaceous genera Calligonum and Pteropyrum using both chloroplast fragment (trnL-F) and the nuclear ribosomal internal transcribed spacer (nrDNA ITS) sequence data. All inferred phylogenies using parsimony and Bayesian methods showed that Calligonum and Pteropyrum are both monophyletic and closely related taxa. They have no affinity w...

Hemlock, Tsuga (Pinaceae), has a disjunct distribution in North America and Asia. To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two we...

Molecular Phylogeny of Asian Meconopsis Based on Nuclear Ribosomal and Chloroplast DNA Sequence Data

The taxonomy and phylogeny of Asian Meconopsis (Himalayan blue poppy) remain largely unresolved. We used the internal transcribed spacer (ITS) region of nuclear ribosomal DNA (nrDNA) and the chloroplast DNA (cpDNA) trnL-F region for phylogenetic reconstruction of Meconopsis and its close relatives Papaver, Roemeria, and Stylomecon. We identified five main clades, which were well-supported in th...

Phenetic analysis of morphological characters in different species of Onobrychis Miller sect. Hymenobrychis DC. (Fabaceae), classified them in two main groups based on corolla features. To determine the phylogenetic relationships among the 13 species, chloroplast DNA sequences were used. Analysis of these data resulted in a well-resolved and well-supported phylogeny. Phylogenies generated by ma...

Phylogeny and Biogeography of Cercis (Fabaceae): Evidence from Nuclear Ribosomal ITS and Chloroplast ndhF Sequence Data

The phylogeny of Cercis (Fabaceae) was estimated with DNA sequences of the nuclear ribosomal ITS region and the 39 end of the chloroplast gene ndhF. The combined analysis recovers three trees in which a well supported clade of North American and western Eurasian species is nested within a paraphyletic group of Chinese species. In the single most unambiguously resolved topology from these trees,...
