FIG 2.
Spike phylogeny of representative β-genus lineage b coronaviruses. The spike protein sequences of selected β-genus lineage b coronaviruses were aligned and phylogenetically compared. Sequences were aligned using free end gaps with the Blosum62 cost matrix in Geneious Prime. The tree was constructed using the neighbor-joining method based on the multiple sequence alignment, also in Geneious Prime. Numbers at the end of each sequence correspond to the GenBank accession number. The radial phylogram was exported from Geneious and then rendered for publication using EvolView (evolgenius.info) and Adobe Illustrator CC 2020.
