Phylogenetic tree based on CP gene sequences.

<p>Phylogenetic tree illustrating relationships between the CP genes of isolates obtained from China and representative isolates of sweet potato chlorotic stunt virus (SPCSV) deposited in GenBank. Neighbor-joining trees were constructed via the maximum composite likelihood substitution model using MEGA (version 4.0). The bar in this figure represents 0.02 Kimura nucleotide unites. Numbers at branches represent bootstrap values of 1000 replicates.
