摘要: The whole genome sequence of mulberry crinivirus (MuCV), a novel member of the genus Crinivirus (family Closteroviridae) identified in mulberry (Morus alba L), was determined. The virus possesses a bipartite genome. RNA1 contains 8571 nucleotides (nt) with four open reading frames (ORFs). ORF1a encodes a putative polyprotein with papain-like protease, methyltransferase, and RNA helicase domains. ORF1b putatively encodes an RNA-dependent RNA polymerase (RdRp), which is probably expressed via a + 1 ribosomal frameshift. RNA2 consists of 8082 nt, containing eight ORFs that are similar in size and position to orthologous genes of other criniviruses. Phylogenetic analysis based on RdRp amino acid sequences of criniviruses placed MuCV in group 1.
