<p>(A) Highlighter plot of SIV <i>env</i> nucleotide sequences from blood plasma (red), epididymis (purple), axillary lymph node (green), prostate (yellow), seminal vesicle (blue) and testis (orange) in male macaque 36338, 11 weeks post infection with SIVmac251. Individual nucleotide polymorphisms are indicated by green (adenine), red (thymine), yellow (guanine), or blue (cytosine) ticks and are in comparison to master sequence 1BP11_01. Gaps are indicated in gray. (B) Highlighter plot of SIV env amino acid sequences from tissues.</p
