Abstract

The complete genomic sequence of Celery mosaic virus (CeMV) was found to be 9999 nucleotides in length, excluding the 3′ poly(A) tail. The genome contains a single large open reading frame encoding a polyprotein of 3181 amino acids. Its genomic organization is typical of potyviruses and contains conserved motifs found in members of the genus Potyvirus. Pairwise comparison of the polyprotein sequences shows that CeMV shares 39.0-71.9% sequence identity with other members of the genus Potyvirus. Phylogenetic analysis based on the polyprotein sequences indicates that CeMV is most closely related to Apium virus Y, and together with Panax virus Y, the three viruses form a distinct clade.
