Transcriptional profile of 49 detected cir genes throughout the IDC. 49 cir transcripts could be detected by microarray, which are listed along with sub-family classifications, next to their pattern of expression throughout the IDC, A). Black shading indicates no change in cir expression for the iRBC population, whilst magenta and green shading indicate higher and lower levels of cir transcripts, respectively. Unclassified cir genes are denoted by/. Representative parasite stages from four of the time-points throughout the 24 hr IDC are shown, B).
