FIG. 3.

Subregion tree analysis of the novel identified CRF65_cpx. The phylogenetic trees of the 14 mosaic segments defined by bootscanning plot analysis were constructed with MEGA 5.0 using the neighbor-joining method. The stability of the nodes was assessed by bootstrap analysis with 1,000 replications, and bootstrap values of 0.7 and higher are shown. The subtypes of sequences are listed on the right side of the trees, and the sequences of subtype B, C, CRF01_AE and CRF65_cpx are bold marked, respectively. The scale bars are shown at the bottom of each tree.
