Phylogenetic tree of the nucleotide sequences of PDCoV isolates based on the complete genome. All the reference sequences used in this study were obtained from the GenBank database. The names of the strains, places of isolation and GenBank accession numbers are shown in Table 1. The Tree was constructed by the neighbour‐joining method with 1,000 bootstrap replications using MEGA 7.0.14 software. The isolate identified in this study is indicated by black triangle, and the Chinese reference strains are indicated by black dots
