Figure 2. Phylogenetic analyses of spike protein (A) and nucleocapsid protein (B) of virus strains of 4 coronavirus genera (Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus), including the porcine coronavirus HKU15 OH1987 strain (indicated with triangle)The dendrogram was constructed by using the neighbor-joining method in the MEGA software package, version 6.05 (http://www.megasoftware.net/)Bootstrap resampling (1,000 replications) was performed, and bootstrap values are indicated for each nodeReference sequences obtained from GenBank are indicated by strain name and accession numberScale bars represent 0.1 aa substitutions per sitePEDV, virus and porcine epidemic diarrhea virus; PRCV, porcine respiratory coronavirus; TGEV, transmissible gastroenteritis virus; PHEV, porcine hemagglutinating encephalomyelitis virus; SARS, severe acute respiratory syndrome.
