Figure 1: Phylogenetic analysis of the nucleotide sequences of 17 new complete genomes from China and all 6 particular relevant sequences currently available in GenBank.

Sequences from the present study (black closed triangles) are named as previously mentioned. Sequences from GenBank were given the country name followed by accession number. The four major groups were identified as A, B, C, and D in yellow, green, blue, and red, respectively. The percentages of replicate trees in which the associated taxa are clustered together in the bootstrap test (1000 replicates) are shown next to the branches.
