Fig. 1

Time-dependent directional changes in nucleotide compositions. a Average mononucleotide compositions (%) in the SARS-CoV-2 genomes of each clade isolated in each month are plotted against the elapsed month. To compare the four mononucleotides, the scale widths on the vertical axis are set to the same values. The colored lines distinguishing the clade (G, GH, GR, L, V and S) are shown at the bottom of the figure. The dashed line shows the averaged compositions for all strains isolated in each month. b The average di- and trinucleotide compositions that primarily undergo common directional changes among the six clades are plotted against the elapsed month
