This study identifies common deletions and defective RNAs in field-collected Powassan virus-infected ticks and shows changes in deletion expression after cell passage.

This study examines in vitro phenotypic diversity of North American Powassan virus isolates and finds broad differences in replication and cytopathic ability unrelated to geographic or temporal origin or specific genotypes.

Tiled-ClickSeq enables complete SARS-CoV-2 genome sequencing with detection of RNA recombination and minority variants in a single assay.

This study identifies differential defective RNA (D-RNA) diversity between intracellular and encapsidated alphavirus compartments, showing that some D-RNAs arise de novo and are not packaged, with subgenomic D-RNAs identified as a novel subtype.
