To be or not to be a virus: A novel chimeric circular Rep-encoding single stranded DNA virus with interfamilial gene exchange illustrates the considerable evolutionary capacity of ssDNA viruses Open
Viruses in the family Geminiviridae cause significant economic losses in numerous crops worldwide. Some geminiviruses are often associated with satellite DNA molecules, such as alphasatellites (familly Alphasatellitidae ), that require the…

Aquatic Biotas of Sundaland Are Fragmented But Not Refugial Open
Tropical insular systems have long attracted biologists, stimulating some important controversies in ecology and evolution. Eustatic fluctuations during the Pleistocene have been invoked to explain species dispersal and proliferation in th…

Reconstructing the Mastrevirus communities structure on La Réunion: The tale of agricultural associated pathogens Open
The geographical distribution and diversity of viruses can differ between cultivated areas and adjacent natural environments, raising questions about the interplay between plant diversity and the species richness and prevalence of the phyt…

Virome release of an invasive exotic plant species in southern France Open
The increase in human-mediated introduction of plant species to new regions has resulted in a rise of invasive exotic plant species (IEPS) that has had significant effects on biodiversity and ecosystem processes. One commonly accepted mech…

Metagenomics reveals the structure of <i>Mastrevirus</i>–host interaction network within an agro-ecosystem Open
As highly pervasive parasites that sometimes cause disease, viruses are likely major components of all natural ecosystems. An important step towards both understanding the precise ecological roles of viruses and determining how natural com…

Virion-Associated Nucleic Acid-Based Metagenomics: A Decade of Advances in Molecular Characterization of Plant Viruses Open
Over the last decade, viral metagenomic studies have resulted in the discovery of thousands of previously unknown viruses. These studies are likely to play a pivotal role in obtaining an accurate and robust understanding of how viruses aff…

Nanopore Sequencing Is a Credible Alternative to Recover Complete Genomes of Geminiviruses Open
Next-generation sequencing (NGS), through the implementation of metagenomic protocols, has led to the discovery of thousands of new viruses in the last decade. Nevertheless, these protocols are still laborious and costly to implement, and …
