High sequence conservation among cucumber mosaic virus isolates from lily

Arch Virol. 2001 Aug;146(8):1631-6. doi: 10.1007/s007050170085.

Abstract

For classification of Cucumber mosaic virus (CMV) isolates from ornamental crops of different geographical areas, these were characterized by comparing the nucleotide sequences of RNAs 4 and the encoded coat proteins. Within the ornamental-infecting CMV viruses both subgroups were represented. CMV isolates of Alstroemeria and crocus were classified as subgroup II isolates, whereas 8 other isolates, from lily, gladiolus, amaranthus, larkspur, and lisianthus, were identified as subgroup I members. In general, nucleotide sequence comparisons correlated well with geographic distribution, with one notable exception: the analyzed nucleotide sequences of 5 lily isolates showed remarkably high homology despite different origins.
