Characterization of the complete genome of a novel allexivirus infecting Sauropus androgynus in China

Arch Virol. 2024 Dec 13;170(1):16. doi: 10.1007/s00705-024-06202-4.

Abstract

A new virus was found in Sauropus androgynus plants with curled and yellow leaves in China and tentatively named "Sauropus androgynus virus" (SaV). The complete genome of SaV is an 8007-nucleotide-long (+)RNA, excluding the 3'-poly(A) tail, and contains five open reading frames. Both pairwise comparisons and phylogenetic analysis of the putative replicase and coat proteins showed that SaV has a high level of sequence similarity to members of the genus Allexivirus of the family Alphaflexiviridae. This is the first report of an allexivirus in Sauropus androgynus.
