Data mining sheds light on a novel family of plant-associated negative-sense RNA viruses linked to lispiviruses

Large-scale mining of public transcriptomic datasets can reveal viral diversity that remains invisible to conventional virus-surveillance approaches, while increasingly powerful structure-prediction methods provide a complementary route to characterizing highly divergent viral proteins. Here, we combine sequence detect...

Complete genome sequence of a novel alternavirus infecting Fusarium falciforme

The complete genome sequence of a novel alternavirus, tentatively named Fusarium falciforme alternavirus 1 (FfAV1)”, isolated from Fusarium falciforme is presented and it is proposed that FfAV1, along with the two closely related unassigned alternaviruses, represents a new species within the genus Alternavirus.

Discovery of novel viruses related to the Potyviridae family reveals expanded diversity, a broad host range, and evidence of fungal and oomycete infections

These findings substantially expand the host range of Potyviridae, provide compelling evidence that potyvirid-like viruses likely infect fungi and oomycetes in nature, and offer new insights into the evolutionary pathways that have shaped this major virus family.

Resolving the Phylogenetic Placement of the FSfaCV/PCV5‐Related Viruses Within the Genus Macochavirus

Sequence identity, genetic distance, and nucleotide diversity analyses supported reclassification of putative PCV5 as a porcine‐associated lineage within the genus Macochavirus, designated porcine Macochavirus (PMV), thereby resolving their long‐standing taxonomic ambiguity and expanding the recognized diversity of cre...

Molecular characterization of a novel partitivirus harboring an additional third dsRNA segment from Trichoderma harzianum

ThPV4 is the first member of the genus Alphapartitivirus identified from T. harzianum to possess an additional, conserved third dsRNA segment, and is the first member of the genus Alphapartitivirus of the family Partitiviridae to possess an additional, conserved third dsRNA segment.

Experimental characterization of zeta viruses and discovery of betaviroid-like RNAs expand the diversity of coding circular RNA replicons

Viroid-like RNAs (vdlRNAs) are infectious agents characterized by single-stranded circular genomes folding into compact secondary structures, often containing self-cleaving ribozymes involved in replication. Recent metatranscriptomic studies have expanded their diversity across multiple ecological niches and revealed n...
