Phylogenetic relationship of CMV isolates on the basis of concatenation of nucleotide sequences of MP, CP and 3′NTR using Simplot.

<p>Four US CMV isolates, (a) BORU93, (b) HORU94, (c) V154NYT85, and (d) AORU93 were used as query sequences and six CMV isolates as reference sequences. Y-axis varies in identity percentage within a sliding window of 200 bp and a step size of 20 bp. Black vertical dashed line shows the proposed recombination break point. Sequences compared with the query sequence are indicated in the legend.</p>
