From: Comprehensive analysis of the overall codon usage patterns in equine infectious anemia virus
Genetic relationship based on synonymous codon usage in EIAV. (A) A plot of the values of the first axis and the second axis of gag, pol, and env in principle component analysis. EIAV field strain Miyazaki2011-A was indicated by black arrow. (B) A plot of the values of the first axis and the second axis of EIAV strains isolated from China (green), Japan (blue), and America (red) in principle component analysis. EIAV field strain Miyazaki2011-A was indicated by black arrow, EIAV strains V70 and V26 was indicated by blue arrow.
