Open AccessNo species-level losses of s2m suggests critical role in replication of SARS-related coronaviruses
The genetic element s2m has been acquired through horizontal transfer by many distantly related viruses, including the SARS-related coronaviruses. Here we show that s2m is evolutionarily conserved in these vir...

Open AccessCharacterization of a new case of XMLV (Bxv1) contamination in the human cell line Hep2 (clone 2B)
The use of misidentified cell lines contaminated by other cell lines and/or microorganisms has generated much confusion in the scientific literature. Detailed characterization of such contaminations is therefo...

Open AccessHorizontal transfer and evolution of transposable elements in vertebrates
Horizontal transfer of transposable elements (HTT) is an important process sha** eukaryote genomes, yet very few studies have quantified this phenomenon on a large scale or have evaluated the selective const...

Open AccessGenomics analysis of Aphanomyces spp. identifies a new class of oomycete effector associated with host adaptation
Oomycetes are a group of filamentous eukaryotic microorganisms that have colonized all terrestrial and oceanic ecosystems, and they include prominent plant pathogens. The Aphanomyces genus is unique in its abilit...

Pan-arthropod analysis reveals somatic piRNAs as an ancestral defence against transposable elements
In animals, small RNA molecules termed PIWI-interacting RNAs (piRNAs) silence transposable elements (TEs), protecting the germline from genomic instability and mutation. piRNAs have been detected in the soma i...

Open AccessDiversity and evolution of sex determination systems in terrestrial isopods
Sex determination systems are highly variable in many taxa, sometimes even between closely related species. Yet the number and direction of transitions between these systems have seldom been characterized, and...

Open AccessComparative paleovirological analysis of crustaceans identifies multiple widespread viral groups
The discovery of many fragments of viral genomes integrated in the genome of their eukaryotic host (endogenous viral elements; EVEs) has recently opened new avenues to further our understanding of viral evolut...

Open AccessPopulation genomics supports baculoviruses as vectors of horizontal transfer of insect transposons
Horizontal transfer (HT) of DNA is an important factor sha** eukaryote evolution. Although several hundreds of eukaryote-to-eukaryote HTs of transposable elements (TEs) have been reported, the vectors underl...

Open AccessHorizontal transfer of transposons between and within crustaceans and insects
Horizontal transfer of transposable elements (HTT) is increasingly appreciated as an important source of genome and species evolution in eukaryotes. However, our understanding of HTT dynamics is still poor in ...

Endogenous viruses: insights into viral evolution and impact on host biology
Recent studies have shown that in addition to vertebrate retroviruses, virtually all types of eukaryotic viruses can be endogenized: that is, they can be integ...

Open AccessA cross-species comparison of escape from X inactivation in Eutheria: implications for evolution of X chromosome inactivation
Sex chromosome dosage compensation in both eutherian and marsupial mammals is achieved by X chromosome inactivation (XCI)—transcriptional repression that silences one of the two X chromosomes in the somatic ce...

A role for host–parasite interactions in the horizontal transfer of transposons across phyla
The horizontal transfer (HT) of genetic material between non-mating species, common in bacteria, is increasingly being recognized as a significant force in eukaryotic evolution. Most instances of HT described ...

Physical map** of the elephant X chromosome: conservation of gene order over 105 million years
All therian mammals (eutherians and marsupials) have an XX female/XY male sex chromosome system or some variant of it. The X and Y evolved from a homologous pair of autosomes over the 166 million years since t...

Chromosome evolution in the subtribe Bovina (Mammalia, Bovidae): The karyotype of the Cambodian banteng (Bos javanicus birmanicus) suggests that Robertsonian translocations are related to interspecific hybridization
Three subspecies of banteng (Bos javanicus) have been described: B. j. javanicus in Java, B. j. lowi in Borneo, and B. j. birmanicus in Cambodia, Lao PDR, Myanmar, Thailand and Vietnam. In this paper we provide t...
