A multipartite virus functionally spreads its distinct genome segments in distinct individual cells of the host plant, and complementation of the viral genes across cells allows a pluricellular infection cycle.

Data-driven methods predict over 35 mosquitoes are potential vectors of Zika virus, suggesting a larger geographic area and a greater human population is at risk of infection.

A global map of environmental suitability for Zika virus and the estimated population living at potential risk can help refine public health guidelines, travel advisories and intervention strategies at a crucial time in the global emergence of this arbovirus.

The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.

Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

The Dengue virus contains discretely folded RNA structures that confer the ability to resist a powerful host cell enzyme and produce a disease-inducing noncoding RNA.

From public microbial genomes, VirSorter revealed 12,498 viral genome sequences that expand the map of the global virosphere and whose analyses improve understanding of viral taxonomy, evolution and virus-host interactions.

The Zika virus subgenomic flaviviral RNA binds to and inhibits the fragile X mental retardation protein, a novel Zika virus restriction factor.

Interactions between viral genomes within the same cells can impact the selection of drug-resistant variants and this has been finessed by hepatitis C virus.

The packaging signal in HIV-1 genomic RNA supports in vitro particle assembly more efficiently than control RNAs, probably explaining its selective packaging during virus assembly in vivo.
