Host codon usage selection pressure on Rep gene of CRESS-DNA virus evolution. (A) Representing the A, T, G, and C fraction; (B) representing the ENc values; (C) representing the codon usage fraction and RSCU values; (D) representing ENc plotted against GC3s; (E) neutrality plot analysis of the GC12 and that of the GC3; and (F) parity rule 2 (PR2)-bias plot. (Total of 1,115 nucleotide sequences of Rep gene of CRESS-DNA viruses were used in this analysis.
