Genetic recombination analysis of the complete spike (S) of C21041821-2 strain. (a) The results of a SimPlot similarity analysis. (b) The results of a bootscanning analysis. The C21041821-2 strain was used as the query sequence and was compared with three other representative strains of CCoV-like viruses, including CCoV B363 ZJ 2019 (MT114541.1), CCoV 2020/7 (MT906865.1), and CCCoV 68/09 (HQ450377.1). A similarity of 1.0 indicates 100% identity with the nucleotide sequence. A window size of 100 bp, a step size of 20 bp, and 100 replicates were used as the default settings.
