Variability in P1 gene redefines phylogenetic relationships among cassava brown streak viruses

Virology Journal, 2017
Background Cassava brown streak disease is emerging as the most important viral disease of cassava in Africa, and is consequently a threat to food security.

Women in the European Virus Bioinformatics Center

Viruses, 2022
Viruses are the cause of a considerable burden to human, animal and plant health, while on the other hand playing an important role in regulating entire ecosystems. The power of new sequencing technologies combined with new tools for processing “Big Data”

THE EVOLUTION OF VIRULENCE IN A PLANT VIRUS [PDF]

Evolution, 2003
The evolution of virulence is a rapidly growing field of research, but few reports deal with the evolution of virulence in natural populations of parasites. We present here an observational and experimental analysis of the evolution of virulence of the plant virus Cucumber mosaic virus (CMV) during an epidemic on tomato in eastern Spain. Three types of

Natural Populations from the Phytophthora palustris Complex Show a High Diversity and Abundance of ssRNA and dsRNA Viruses

Journal of Fungi, 2022
We explored the virome of the “Phytophthora palustris complex”, a group of aquatic specialists geographically limited to Southeast and East Asia, the native origin of many destructive invasive forest Phytophthora spp. Based on high-throughput sequencing (

Comparison of SARS-CoV-2 Evolution in Paediatric Primary Airway Epithelial Cell Cultures Compared with Vero-Derived Cell Lines

Viruses, 2022
SARS-CoV-2 can efficiently infect both children and adults, albeit with morbidity and mortality positively associated with increasing host age and presence of co-morbidities.

Exceptional Convergent Evolution in a Virus [PDF]

Genetics, 1997
Abstract Replicate lineages of the bacteriophage ϕX 174 adapted to growth at high temperature on either of two hosts exhibited high rates of identical, independent substitutions. Typically, a dozen or more substitutions accumulated in the 5.4-kilobase genome during propagation. Across the entire data set of nine lineages, 119 independent

Dating the Emergence of Human Endemic Coronaviruses

Viruses, 2022
Four endemic coronaviruses infect humans and cause mild symptoms. Because previous analyses were based on a limited number of sequences and did not control for effects that affect molecular dating, we re-assessed the timing of endemic coronavirus ...

Recombination and Positive Selection Differentially Shaped the Diversity of Betacoronavirus Subgenera

Viruses, 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]

Journal 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 ...

Unveiling Crucivirus Diversity by Mining Metagenomic Data

mBio, 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
