cir gene expression during infection. The percentage of cir genes for which transcripts were detected by RNA sequencing is shown for the four P. chabaudi infected BALB/c mice, A). The ten dominant cir s were tabulated from each infected mouse, ranked according to expression level, B). The number of P. chabaudi infected BALB/c mice for which a dominant cir transcript was detected is plotted, C). The densities of all P. chabaudi transcripts and cir transcripts are plotted against the log2 RPKM, a measure of transcript abundance, coloured in black and pale grey respectively, D). Regions of overlap are dark grey.
