چکیده

As a discipline, phylogenetics is becoming transformed by a flood of molecular data. These data allow broad questions to be asked about the history of life, but also present difficult statistical and computational problems. Bayesian inference of phylogeny brings a new perspective to a number of outstanding issues in evolutionary biology, including the analysis of large phylogenetic trees and complex evolutionary models and the detection of the footprint of natural selection in DNA sequences.

Phylogeny and morphological traits evolution of Astragalus sects. Acanthophace and Aegacantha in Iran on the basis of nrDNA ITS and rpl32-trnLUAG sequences

In this study, phylogenetic relationships and evolutionary trends of morphological characters of Astragalus sects. Acanthophace and Aegacantha were studied using nrDNA ITS and rpl32-trnLUAG datasets while Astragalus stocksii was selected as the outgroup. The phylogenetic results indicated the non-monophyly of A. sect. Acanthophace in its current circumscription due to the distant exclusion of A...

The Phylogeny of Calligonum and Pteropyrum (Polygonaceae) Based on Nuclear Ribosomal DNA ITS and Chloroplast trnL-F Sequences

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...

Molecular phylogeny of Scutellaria (Lamiaceae; Scutellarioideae) in Iranian highlands inferred from nrITS and trnL-F sequences

Scutellaria with about 360 species is one of the largest genera of Lamiaceae. The Iranian highlands accommodate about 40 Scutellaria spp., and is considered as one of the main centers of diversity of the genus. Here, we present a phylogenetic study for 44 species of Scutellaria especially from Iranian highlands, representing major subgeneric taxa, based on nuclear rib...

Molecular phylogeny of the family Araceae as inferred from the nuclear ribosomal ITS data

The internal transcribed spacer regions of nuclear ribosomal DNA are widely used to infer phylogenetic relationships in plants. In this study, it was obtained the ITS sequences from 24 samples of Araceae in Iran, representing 3 genera: Arum L., Biarum Schott. and Eminium (Blume) Schott. Phylogenetic analyses were conducted by Bayesian inference and maximum Parsimony methods. Cladistic analysis ...

Bayesian Phylogenetic Inference from Animal Mitochondrial Genome Arrangements

The determination of evolutionary relationships is a fundamental problem in evolutionary biology. Genome arrangement data is potentially more informative than DNA sequence data for inferring evolutionary relationships among distantly related taxa. We describe a Bayesian framework for phylogenetic inference from mitochondrial genome arrangement data using Markov chain Monte Carlo methods. We app...
