Effective number of codons (ENC) used in BCoV ORFs plotted against the GC3S The orange curve plots the relationship between GC3S and ENC in absence of selection. Blue dots show the results obtained for BCoV strains. Note that the values obtained for ENC and GC3S of all 15 BCoVs enrolled in these studies are very similar (SD of ±0.07 and ±0.0009, respectively) and for that reason they resemble a single dot in the figure
