Bayesian phylogenetic trees of CMV isolates based on six genomic regions including field collected and reference isolates.

(a) 1a, partial sequence; (b) 2a, partial sequence; (c) 2b, complete sequence; (d) MP, complete sequence; (e) CP, complete sequence; and (f) RNA3 3’NTR complete sequence. Numbers above branches indicate Bayesian inference posterior probability (PP). CMV subgroups are differentiated by colors: IA  =  green, IB  =  orange, II  =  purple. Reassortants have illustrated in bold.
