Complete nucleotide sequence and the genome organization of Patchouli mild mosaic virus RNA1

The nucleotide sequence of the RNA1 of Patchouli mild mosaic virus (PatMMV) has been determined. It contains 5,957 nucleotides excluding the 3'-terminal poly(A) tail and contains a single long open reading frame (ORF) of 5,613 nucleotides extending from nucleotide 235 to 5847. The predicted polyprotein encoded by the long ORF is 1,870 amino acids in length with a molecular weight of 210 kD. The conserved residues of RNA-dependent RNA polymerase, cysteine protease, purine NTP-binding domain and a cofactor for viral protease are present in a 210-kD polyprotein. As PatMMV RNA showed high sequence identity (81-97%) with BBWV-2 RNA, PaMMV may be one strain of BBWV-2.
