Tridimensional model structure and patterns of molecular evolution of Pepino mosaic virus TGBp3 protein

Virology Journal, 2011
Background Pepino mosaic virus (PepMV) is considered one of the most dangerous pathogens infecting tomatoes worldwide. The virus is highly diverse and four distinct genotypes, as well as inter-strain recombinants, have already been described.

Evidence for RNA recombination between distinct isolates of Pepino mosaic virus. [PDF]

, 2010
Genetic recombination plays an important role in the evolution of virus genomes. In this study we analyzed publicly available genomic sequences of Pepino mosaic virus (PepMV) for recombination events using several bioinformatics tools.

Geometry and virus evolution [PDF]

Science, 2015
Influenza An influenza pandemic is only a couple of mutations away. Or is it? Meyer and Wilke analyzed how the hemagglutinin protein of the H3 subtype of influenza has evolved, to learn how mutation allows this virus to escape host immune surveillance.

Virus Evolution [PDF]

Cell, 2001
The evolution of viruses has been an exciting area of study, albeit an area that is fraught with difficulties be- cause of the lack of a fossil record and because of the rapid sequence divergence exhibited by viruses. All viruses in collections available for study in the laboratory have been isolated within the last 70 years.

Single‐cell insights into the role of T cells in B‐cell malignancies

FEBS Letters, EarlyView.
Single‐cell technologies have transformed our understanding of T cell–tumor cell interactions in B‐cell malignancies, revealing new T‐cell subsets, functional states, and immune evasion mechanisms. This Review synthesizes these findings, highlighting the roles of T cells in pathogenesis, progression, and therapy response, and underscoring their ...

Family Level Phylogenies Reveal Relationships of Plant Viruses within the Order Bunyavirales

Viruses, 2020
Bunyavirales are negative-sense segmented RNA viruses infecting arthropods, protozoans, plants, and animals. This study examines the phylogenetic relationships of plant viruses within this order, many of which are recently classified species ...

Spread of Gamma (P.1) Sub-Lineages Carrying Spike Mutations Close to the Furin Cleavage Site and Deletions in the N-Terminal Domain Drives Ongoing Transmission of SARS-CoV-2 in Amazonas, Brazil

Microbiology Spectrum, 2022
The Amazonas was one of the most heavily affected Brazilian states by the COVID-19 epidemic. Despite a large number of infected people, particularly during the second wave associated with the spread of the Variant of Concern (VOC) Gamma (lineage P.1 ...

Virus Replication as a Phenotypic Version of Polynucleotide Evolution

, 2013
In this paper we revisit and adapt to viral evolution an approach based on the theory of branching process advanced by Demetrius, Schuster and Sigmund ("Polynucleotide evolution and branching processes", Bull. Math. Biol.
