Fig. 2From: Identification of the first C1 subgenotype of enterovirus 71 in the Chinese mainland in a retrospective studyPhylogenetic Tree Based on EV-A's VP1, P1, P2, and P3 sequences. Note Maximum likelihood trees were constructed using the GTR + G model and were implemented in MEGA7.0 with 1000 bootstrap replicates. The close circle represents the SD92-41 strain. The scale bars indicate the genetic distance. a VP1 coding sequence; b P1 coding sequence; c P2 coding sequence; d P3 coding sequenceBack to article page
