Fig. 2 — The structural–phylogenetic analysis of the 5′-proximal sequences in group I CoVs. The predicted secondary structures of the 5′-proximal sequence of (A) group Ia TGEV-purdue, (B) group Ib HCoV-229E-inf-1, (C) group Ic PEDV-CV777, and (D) group Id BtCoV-1A coronaviruses are shown. Nucleotide variations located in the conserved elements in the other representative CoVs of each subgroup are indicated. The start codon of the ORF1ab is boxed, the core sequence of the transcription-regulating leader (TRS-L CS) is bracketed, and the length of the sequence insertion in SL5 is indicated.
