Analysing the evolutionary history of HCV: Puzzle of ancient phylogenetic discordance

Infection, Genetics and Evolution, 2007
Though recombination is an important evolutionary strategy in RNA viruses, only two cases of HCV recombinant strains have been reported. Our objective was to analyze the evolutionary history of the HCV genotypes aiming to obtain evidence of significant phylogenetic discordance due to either recombination or selective forces leading to convergent ...

Plasmodium vivax-like genome sequences shed new insights into Plasmodium vivax biology and evolution [PDF]

, 2018
Although Plasmodium vivax is responsible for the majority of malaria infections outside Africa, little is known about its evolution and pathway to humans. Its closest genetic relative, P.

Phylogenetic Discordance at the Species Boundary: Comparative Gene Genealogies Among Rapidly Radiating Heliconius Butterflies [PDF]

Molecular Biology and Evolution, 2002
Recent adaptive radiations provide excellent model systems for understanding speciation, but rapid diversification can cause problems for phylogenetic inference. Here we use gene genealogies to investigate the phylogeny of recent speciation in the heliconiine butterflies.

Specimens at the Center: An Informatics Workflow and Toolkit for Specimen-level analysis of Public DNA database data [PDF]

, 2016
Major public DNA databases — NCBI GenBank, the DNA DataBank of Japan (DDBJ), and the European Molecular Biology Laboratory (EMBL) — are invaluable biodiversity libraries. Systematists and other biodiversity scientists commonly mine these databases for

Phylogenetic Congruence and Discordance Among One Morphological and Three Molecular Data Sets from Pontederiaceae [PDF]

Systematic Biology, 1998
A morphological data set and three sources of data from the chloroplast genome (two genes and a restriction site survey) were used to reconstruct the phylogenetic history of the pickerelweed family Pontederiaceae. The chloroplast data converged towards a single tree, presumably the true chloroplast phylogeny of the family. Unrooted trees estimated from

Sage Insights Into the Phylogeny of Salvia: Dealing With Sources of Discordance Within and Across Genomes

Frontiers in Plant Science, 2021
Next-generation sequencing technologies have facilitated new phylogenomic approaches to help clarify previously intractable relationships while simultaneously highlighting the pervasive nature of incongruence within and among genomes that can complicate ...

Phylogenetic surveillance of viral genetic diversity and the evolving molecular epidemiology of human immunodeficiency virus type 1 [PDF]

, 2007
With ongoing generation of viral genetic diversity and increasing levels of migration, the global human immunodeficiency virus type 1 (HIV-1) epidemic is becoming increasingly heterogeneous.

Wolbachia and DNA barcoding insects: patterns, potential and problems [PDF]

, 2012
Wolbachia is a genus of bacterial endosymbionts that impacts the breeding systems of their hosts. Wolbachia can confuse the patterns of mitochondrial variation, including DNA barcodes, because it influences the pathways through which mitochondria are ...

Extensive introgression among strongylocentrotid sea urchins revealed by phylogenomics

Ecology and Evolution, 2023
Gametic isolation is thought to play an important role in the evolution of reproductive isolation in broadcast‐spawning marine invertebrates. However, it is unclear whether gametic isolation commonly evolves early in the speciation process or only ...

Genome-wide signatures of complex introgression and adaptive evolution in the big cats. [PDF]

, 2017
The great cats of the genus Panthera comprise a recent radiation whose evolutionary history is poorly understood. Their rapid diversification poses challenges to resolving their phylogeny while offering opportunities to investigate the historical ...
