Seedless barberry (Berberis vulgaris L. var. asperma) is one of the few crops that is only cultivated in eastern parts of Iran. As a new crop there has not been any study to identify phylogenetic relationships of this plant with other related species existing in Iran. In this study, Amplification fragment length polymorphism (AFLP) markers based on four selected primer combinations (EcoRI/Tru1I...

Aster yellows (AY) group (16SrI) phytoplasmas are associated with more than 100 economically important diseases worldwide and represent the most diverse and widespread phytoplasma group. Phylogenetic analysis of secY gene sequences resolved 10 genetically distinct lineages. The 10 lineages coincide with those delineated by phylogenetic analysis based on ribosomal protein (rp) gene sequences. Ho...

the genus allactaga is a group of rodents with five morphospecies distributed in the iranian plateau. in order to conduct a taxonomic revision at the species level, 27 individuals were collected in the iranian plateau from localities typical of each species. phylogenetic relationships within species were analyzed using cytochrome oxidase subunit i and morphometric data. maximum parsimony, maxim...

Phylogenetic analysis of DNA sequence data from the nuclear CAD (rudimentary) and mitochondrial NDI, COI, and 16S gene regions (2817 bp total) recovered exemplars of the genus Dohrniphora as a monophyletic lineage. The data also supported the sister-group relationship of Dohrniphora + Diplonevra and were used to associate a morphologically dissimilar male and female of the species D. ecitophila...

Anomaluroid rodents show interesting biogeographic and macroevolutionary patterns, although their fossil record is meager and knowledge of the natural history of extant members of the clade remains inadequate. Living anomaluroids (Anomaluridae) are confined to equatorial parts of western and central Africa, but the oldest known fossil anomaluroid (Pondaungimys) comes from the late middle Eocene...

Phylogenetic relationships among the families in the infraorder Sejina and the position of Sejina relative to other infraorders of Mesostigmata are re-examined based on molecular and morphological data. Data sets included DNA sequence data for complete 18S, EF-1α, partial CO1genes, and 69 morphological characters. The two families of Heterozerconina consistently group within Sejina, and we prop...

Most current methods for inferring species-level phylogenies under the coa-lescent model assume that no gene flow occurs following speciation. Several studies have examined the impact of gene flow (e.g., Eckert and Carstens (2008); Chung and Ané (2011); Leaché et al. (2014); Solís-Lemus et al. (2016)) and of ancestral population structure (DeGeorgio and Rosenberg, 2016) on the performance of sp...

Preliminary study on Ipomoea phylogeny shows that species selection may influence flower-color evolution in this genus. Evolutionary transitions between pigmented flower and white flower appear to be highly asymmetrical. White-flowered lineages are less speciose than their pigmented sister clade and evolutionary transitions to white flowers occurred almost exclusively at the tip of phylogeny. A...

Three hundred commensal Escherichia coli recovered from healthy herbivorous, carnivorous, and omnivorous mammals from one zoo were characterized for their phylogenetic origin, intestinal virulence gene (VG) prevalence, and genomic diversity. The phylogenetic structure of the E. coli (groups A, B1, B2, and D) from the herbivores was homogenous, with a prevailing representation of group B1. In th...

Dividing the fossils usually assigned to the taxon Homo habilis sensu lato into two species (as most researchers now accept) necessitates a re-examination of their evolutionary relationships. A cladistic analysis of 48 of the most commonlyused cranial characters from recent studies of Pliocene hominid phylogeny and which distinguish two taxa within H. habilis sensu lato suggests that these foss...
