Re-examination of nepovirus polyprotein cleavage sites highlights the diverse specificities and evolutionary relationships of nepovirus 3C-like proteases [PDF]

Archives of Virology, 2022
AbstractPlant-infecting viruses of the genus Nepovirus (subfamily Comovirinae, family Secoviridae, order Picornavirales) are bipartite positive-strand RNA viruses with each genomic RNA encoding a single large polyprotein. The RNA1-encoded 3C-like protease cleaves the RNA1 polyprotein at five sites and the RNA2 polyprotein at two or three sites ...

Caraway yellows virus, a novel nepovirus from Carum carvi [PDF]

Virology Journal, 2019
A novel nepovirus was identified and characterised from caraway, and tentatively named caraway yellows virus (CawYV). Tubular structures with isomeric virus particles typical for nepoviruses were observed in infected tissues by electron microscopy.

Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]

Physiol Plant
ABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.
