Recombination and Positive Selection Differentially Shaped the Diversity of Betacoronavirus Subgenera

open access: yesViruses, 2020
The Betacoronavirus genus of mammal-infecting viruses includes three subgenera (Sarbecovirus, Embecovirus, and Merbecovirus), in which most known human coronaviruses, including SARS-CoV-2, cluster.

Evolution and Vaccination of Influenza Virus [PDF]

open access: yesJournal of Computational Biology, 2017
In this study, we present an application paradigm in which an unsupervised machine learning approach is applied to the high-dimensional influenza genetic sequences to investigate whether vaccine is a driving force to the evolution of influenza virus. We first used a visualization approach to visualize the evolutionary paths of vaccine-controlled and ...

Dinucleotide evolutionary dynamics in influenza A virus [PDF]

open access: yes, 2019
Significant biases of dinucleotide composition in many RNA viruses including influenza A virus have been reported in recent years. Previous studies have showed that a codon-usage-altered influenza mutant with elevated CpG usage is attenuated in mammalian

A virus responds instantly to the presence of the vector on the host and forms transmission morphs

open access: yeseLife, 2013
Many plant and animal viruses are spread by insect vectors. Cauliflower mosaic virus (CaMV) is aphid-transmitted, with the virus being taken up from specialized transmission bodies (TB) formed within infected plant cells.

Unveiling Crucivirus Diversity by Mining Metagenomic Data

open access: yesmBio, 2020
The discovery of cruciviruses revealed the most explicit example of a common protein homologue between DNA and RNA viruses to date. Cruciviruses are a novel group of circular Rep-encoding single-stranded DNA (ssDNA) (CRESS-DNA) viruses that encode capsid

Immunoinformatic Analysis Reveals Antigenic Heterogeneity of Epstein-Barr Virus Is Immune-Driven

open access: yesFrontiers in Immunology, 2021
Whole genome sequencing of Epstein-Barr virus (EBV) isolates from around the world has uncovered pervasive strain heterogeneity, but the forces driving strain diversification and the impact on immune recognition remained largely unknown.

Elucidating the phylodynamics of endemic rabies virus in eastern Africa using whole-genome sequencing

open access: yes, 2015
Virus Evolution 2015, Vol. 1(1)Many of the pathogens perceived to pose the greatest risk to humans are viral zoonoses, responsible for a range of emerging and endemic infectious diseases.

Evidence of viral adaptation to HLA class I-restricted immune pressure in chronic hepatitis C virus infection [PDF]

open access: yes, 2006
Cellular immune responses are an important correlate of hepatitis C virus (HCV) infection outcome. These responses are governed by the host's human leukocyte antigen (HLA) type, and HLA-restricted viral escape mutants are a critical aspect of this host ...

Participation of Multifunctional RNA in Replication, Recombination and Regulation of Endogenous Plant Pararetroviruses (EPRVs)

open access: yesFrontiers in Plant Science, 2021
Pararetroviruses, taxon Caulimoviridae, are typical of retroelements with reverse transcriptase and share a common origin with retroviruses and LTR retrotransposons, presumably dating back 1.6 billion years and illustrating the transition from an RNA to ...

The evolution of virus–induced apoptosis

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 1997
Viruses from several different families are able to exploit their host's cell death programmes so as to maximize viral fitness. Consideration of the evolution of such strategies has lead to the suggestion that the virus should inhibit apoptosis, in order to prolong the life of the cell and thereby maximize the number of progeny virions.
