Frequency of arginine encoding synonymous codons in the complete genomic coding sequences of (A) chiroptera-hosted alpha- and beta-CoVs, (B) animals and humans-hosted CoVs. (C) shows the distribution patterns of arginine-encoding codons in the furin-like cleavage sites of CoVs infecting different hosts. A p-value less than 0.01 is considered statistically significant, and ns represents non-significant difference between two values.
