Figure Lengend Snippet: Two nucleotide and one amino acid mutations in the complete genome alignment. Multiple sequence alignment was constructed using ClustalW in DNASTAR software. (A) T to C substitution at the 129th nucleotide in the SDDC strain. (B) A to G substitution at the 1452th nucleotide in the SDDC, QD and SDLH strains. (C) Isoleucine to threonine substitution at residue 160 in the Cap protein of the SDDC, QD and SDLH strains. The SDDC, QD and SDLH strains are indicated in bold and highlighted. The dash indicates nucleotide identity with the consensus sequence. (D) Three-dimensional structure prediction of the Cap protein using AlphaFold 3. (a) GX23 2020 strain; (b) SDDC strain; (c) Structural superposition of (a) and (b). Isoleucine/Threonine at position 160 is displayed as a ball-and-stick model with mesh representation to highlight structural features.
