FIG 5.

No set of SNPs is consistently selected in KRCV-1-infected macaques. For each of the four crab-eating macaques, every SNP detected at the last time point at which virus was detectable is plotted. Each dot represents one SNP; different colors represent the different macaques. No SNPs were found at a high frequency at the last time point of infection in all four macaques. Below the plot is a cartoon depiction of the organization of the KRCV-1 genome. Replicase genes are shown in gray, ORFs absent in the nonsimian arteriviruses are shown in blue, and ORFs encoding structural proteins are shown in orange.
