Figure 2

Maximum likelihood phylogeny of deduced H9 hemagglutinin protein sequences. The maximum likelihood tree was established using the IQ-Tree software. Robustness of branching orders was tested by an ultrafast bootstrap approximation algorithm [36]. The tree is drawn to scale and color-coded clading information is shown to the right of the tree. Blue color indicates sequences that were established in the frame of this study. Orange circles depict H9 viruses for further experiments in this study.
