Fig. 1From: Codon usage patterns of LT-Ag genes in polyomaviruses from different host speciesPhylogenetic trees of PyV LT-Ag genes. PyVs were classified according to the host species (mammal, avian, and fish) in the ML-based trees constructed using nucleotide sequences of LT-Ag coding genes, DnaJ domains, and helicase domains (Alphapolyomaviruses []; Betaapolyomaviruses []; Deltapolyomaviruses []; Gammapolyomaviruses []; unassigned [])Back to article page
