Figure 3
Phylogenetic tree of genetic fragments for EV-A90 and other similar serotypes, including P1, P2, P3 and 3CD, were illustrated in figure (a–d). Isolates in this research were marked with 
and the prototype of EV-A90 (BAN00-10399) was marked with 
. The phylogenetic tree was reconstructed using maximum likelihood method, in which GTR + I + G model was used in P1 fragment and TN93 + I + G model was used in the rest fragment. We also put forward a hypothesis between the major parental type (yellow) and the minor parental type (blue) because of recombination.
