From: Analysis of the codon usage pattern of the RdRP gene of mycovirus infecting Aspergillus spp.
Correspondence analysis results using RSCU values (COA-RSCU). Axis1 and Axis2 of the COA-RSCU explained 44.31 and 18.81%, respectively, of the total variation. a COA result for A/C/U/G-ended codons; G- and C-ended codons formed one group and A- and U-ended codons formed one group. b COA result for over-represented codons (RSCU > 1.6); the codons strongly preferred individually by the three viruses formed separate groups
