Complete genome sequence of cnidium closterovirus 1, a novel member of the genus Closterovirus infecting Cnidium officinale.

The genome of a novel virus identified in Cnidium officinale is composed of a monopartite ssRNA of 16,755 nucleotides that shares 68.73% (query coverage, 20%) sequence identity with carrot yellow leaf virus (CYLV, accession no. FJ869862.1). It contains 11 putative open reading frames and has an organization typical of closteroviruses. It shares 30-50% nucleotide sequence identity with other closteroviruses. The heat shock protein 70-like protein (HSP70), putative RNA-dependent RNA polymerase (RdRp), and coat protein (CP) show 39-66%, 16-60%, and 24-41% amino acid sequence identity, respectively, to the homologous proteins of previously identified closteroviruses. Molecular and HSP70-based phylogenetic analysis of the genome and encoded protein sequences suggested that this virus is a novel member of the genus Closterovirus in the family Closteroviridae, which we have tentatively named "cnidium closterovirus 1" (CnClV1). © 2022.
