Figure 1

Phylogenetic tree of the 30 viruses. The first 21 nts were deleted from the sequence alignment due to a gap in one sequence. Baysian Information Criterion (BIC) scores for different models were computed using the MEGA 5.05 program with the default settings. TN93 with a proportional discrete Gamma distribution (+G) and a fraction of invariant sites (+I), was selected as best fitted model with the lowest BIC scores. The transition/transversion bias for TN93 + G + I model was estimated to be 6.85, using MEGA 5.05 under the Kimura 2-parameter model. The maximum likelihood tree constructed by MEGA 5.05 program with default settings and TN93 + G + I model is shown.
