Abstract:

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 maximum likelihood show monophyly of O. sect. Hymenobrychis and the division of the section into two major clades. The first branching clade was formed by all the species of the section with large flowers, a yellowish corolla with or without venation and some species having a larger chromosome number (x=8 vs x=7). The second major clade includes the remaining species studied, all of which have small flowers, a yellowish corolla with or without venation or purple maculae and the common number of chromosomes (x=7). The compliance of the molecular, morphological and cytogenetic data indicates that x=8 is ancestral in the section and x=7 are derived through an aneuploid loss of a chromosome. The resulting phylogeny suggests the Zagros area as an origin of evolution in the sect. Hymenobrychis, followed by a radiation to the Alborz area in Iran.

Phylogeny of Ononis in Iran using nuclear ribosomal DNA and chloroplast sequence data

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 obta...

Molecular Phylogeny of the Genus Lathyrus (Fabaceae-Fabeae) Based on cpDNA matK Sequence in Iran

Background: More than 60 species of the genus Lathyrus are distributed in Southwest Asia. It is the second largest genus of the tribe Fabeae, after Vicia, in the region (and in Iran with 23 species). In the regional Flora (Flora of Turkey, FloraIranicaand flora...

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,...

Solanum Phylogeny Inferred from Chloroplast Dna Sequence Data

A data set derived from gene sequences of ndhF is used to deduce phylogenetic relationships among the subgenera of Solanum, among related genera of the tribe Solaneae, and within selected Solanum clades. Complete ndhF sequences were obtained for 12 species of Solanum, representing five of the seven subgenera. ndhF sequences also were obtained from species of Capsicum, Cyphomandra, Datura, Jalto...

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...

Phylogeny of some species of Astragalus (Fabaceae) based on morphological data

The phylogenetic relationships among 39 species belonging to 12 sections of Astragalus from Iran were studied on the basis of 29 morphological characters. The cladistics analysis of the morphological data was performed using PAUP* 4.0b10 program. The obtained data were compared with the molecular systematics data obtained from nuclear DNA ITS. In contrast with previous molecular systematic stud...
