Differential localization patterns of H3K9Ac, PfSir2 and PfHP1. (A) Differential distribution of PfSir2 and H3K9Ac in Plasmodium falciparum. Dual Immuno-fluorescence analysis of PfSir2 (green) and H3K9Ac (red) reveals PfSir2 as sharp foci around nuclei and H3K9Ac as sharp foci closely attached to nuclei periphery. There is no colocalization of PfSir2 and H3K9Ac in ring stage. Scale bar measures 1 μM. DAPI stains nuclei. (B) Differential distribution of H3K9Ac (green) and PfHP1, specific for H3K9me3 repressive histone marks (red). Dual immuno-fluorescence assay shows no colocalization between these two proteins. Scale bar measures 1 μM. DAPI stains nuclei.
