Phylogenetic networks generalize evolutionary trees, and are commonly used to represent evolutionary histories of species that undergo reticulate evolutionary processes such as hybridization, recombination and lateral gene transfer. Recently, there has been great interest in trying to develop methods to construct rooted phylogenetic networks from triplets, that is rooted trees on three species....

Phylogenetic inference is an intractable statistical problem on a complex space. Markov chain Monte Carlo methods are the primary tool for Bayesian phylogenetic inference, but it challenging to construct efficient schemes explore associated posterior distribution or assess their performance. Existing approaches unable diagnose mixing convergence of jointly across all components model. Lagged co...

Background: The emergence and propagation of different phylogenetic groups of antimicrobial-resistant E. coli have become a worldwide health concern in human and veterinary medicine. Therefore, the evaluation of the phylogenetic distribution of antibiotic-resistant E. coli is important for therapeutic and economic purposes. The aims of this study were to determine phylogenetic groups and patter...

results the present work figured out that the heterogeneity of the quasispecies of our local strains 4a was high showing up 15% diversity. this study also showed four glycosylation sites that play an important role in the entry of the virus and protein folding. besides, different epitpoes were identified in different regions of the e1 and e2 domains; a finding which would help in determining th...

peanut plants showing mottling, yellow and necrotic spots on leaves were collected from peanut fields in golestan province. electron microscopic studies revealed the presence of flexuous filamentous particles ca. 700 nm in length, which was suggestive of a potyvirus infection. healthy nicotiana benthamiana plants mechanically inoculated with sap from infected peanut plants showed mottling, down...
