Résumé
A novel positive-stranded RNA virus provisionally named "citrus virus C" (CVC) was discovered in citrus trees displaying mottling symptoms. Its genome comprises 7,215 nucleotides (nt), excluding the 3' poly(A) tail, and contains two open reading frames (ORFs) that encode a replication-associated polyprotein (RP) and a putative coat protein (CP). The CVC genome contains a 16-nt 'marafibox', which is highly conserved in most viruses belonging to the genus Marafivirus of the same family. Sequence analysis suggested that the virus is most closely related to grapevine Red Globe virus (GRGV), which is yet to be officially classified in the family Tymoviridae. The sequence identities between CVC and GRGV in the whole genome (50.7%, nt) and CP (49.4% for amino acid, and 53.9% for nt) are lower than the thresholds (80% in the genome and 90% in the CP) for species demarcation in the family. Therefore, it is legitimate to propose that CVC is a member of new species in the family Tymoviridae.
