Complete nucleotide sequence and genome organization of Calibrachoa mottle virus (CbMV)—A new species in the genus Carmovirus of the family Tombusviridae
چکیده انگلیسی

Complete genomic sequence of the viral RNA of Calibrachoa mottle virus (CbMV) has been determined. The CbMV genome has a positive-sense single-stranded RNA of 3919 nucleotides in length and encodes five open reading frames (ORFs). ORF1 encodes a protein with predicted molecular weight of 28 kDa (p28). ORF2 extends through the amber stop codon of ORF1 to give a protein with a predicted molecular weight of 87 kDa (p87). The readthrough domain of p87 contains the GDD motif common to RNA-dependent RNA polymerases (RdRp). ORF3 and ORF4 encode two small overlapping polypeptides of 8 kDa (p8) and 9 kDa (p9), respectively. The 3′-proximal ORF5 encodes a capsid protein (CP) of 37 kDa (p37). The untranslated 5′- and 3′-terminal regions are composed of 34 and 234 non-coding nucleotides, respectively. Comparisons of amino acid sequences of the ORFs of CbMV with members of Tombusviridae show that CbMV is closely related to members of the genus Carmovirus. Phylogenetic analyses based on the amino acid sequences of RdRp and coat protein and nucleotide sequences of the whole genome reveal that CbMV forms a subgroup with several carmoviruses. Therefore, the genome organization, physico-chemical properties, sequence alignments and phylogenetic analysis support the classification of CbMV as a new species in the genus Carmovirus, family Tombusviridae.
