Abstract excerpt
Vaccinia virus (VACV) is a member of the Poxviridae family and served as the vaccine strain used to eradicate smallpox. As a large double-stranded DNA virus, VACV exhibits a broad host range and remains a model organism for studying viral evolution and gene expression. Codon usage bias (CUB) is a fundamental feature of genome evolution that reflects the interplay between mutational pressure and natural selection....
