Abstract Most members of the genus Gammacoronavirus infect avian hosts, but far fewer viruses have been characterized than in the other coronavirus genera, leaving their diversity largely unclear. Pigeon gammacoronaviruses were previously detected by consensus PCR, but only partial sequences were determined. In this study, we comprehensively analyzed public RNA-seq datasets and reconstructed two nearly complete genomes of pigeon gammacoronaviruses.

Abstract Viruses in the family Kolmioviridae (KoVs) are unique among RNA viruses in that they have small, highly self-complementary, circular, negative-sense genomes and are satellite viruses requiring the envelope protein of co-infected helper viruses to form infectious virions. For approximately 40 years, only hepatitis D virus (HDV) had been identified, but recent studies have uncovered novel KoVs in diverse animal species.
