A midpoint rooted cladogram of betacoronavirus Lineage A viruses. Representative strains from Genbank were used (Accession Numbers outlined in Table 2). MUSCLE [22] was used to align the sequences in MEGA X [23]. A Neighbour-Joining cladogram was generated. A linear schematic of the HE glycoprotein lectin and esterase domains is also indicated for each virus (Esterase in orange and Lectin in purple). The receptor bound by the relevant domain is annotated accordingly.
