. . . . . Phylogenetic analyses of spike protein of dromedary camel coronavirus (DcCoV) UAE-HKU23from dromedaries of the Middle East, 2013.The tree was constructed by the neighbor-joining method, using Jones-Taylor-Thornton substitution model with gamma distributed rate variation and bootstrap values calculated from 1,000 trees. Bootstrap values of <70% are not shown. A total of 1,366 aa positions in spike protein were included in the analysis. The tree was rooted to Breda virus (GenBank accession no. AY_427798).Betacoronavirus lineages A1 and A–D are indicated on the right. Boldface indicates the 3 strains of DcCoV UAE-HKU23 characterized in this study.
