PfAtg8 localizes to the apicoplast. P. falciparum FCR3 (A–E) and P. falciparum 3D7 transfected with ACP-GFP (F–H) were stained with the indicated organelle markers and visualized by confocal microscopy (because ACP-GFP was not uniformly expressed, some merozoites displayed only faint GFP signals). Anti-PfAtg8 antibody #1 was used in (A–F), and anti-PfAtg8 antibody #2 was used in (G). Apical membrane antigen 1 (AMA1) as a microneme marker (A), rhoptry-associated protein 1 (RAP1) as a rhoptry body marker (B), rhoptry neck protein 2 (RON2) as a rhoptry neck marker (C), the ring-infected erythrocyte surface antigen (RESA) as a dense granule marker (D), MitoTrackerRed CMXRos as a mitochondria marker (E), ACPGFP (F–H) and the organellar histone-like protein PfHU (H) as an apicoplast marker were used.

Localization of PfHU. (A) Immunolocalization of PfHU using confocal microscopy. Panels show nuclear DNA staining with DAPI (1), PfHU fluorescence (2), MitoTracker Red signal (3) and their overlap (4) in a late trophozoite. The corresponding phase–contrast scan is shown in (5). (B) Co-localization of PfHU and apicoplast-targeted GFP. Nuclear DNA stained with DAPI (1), PfHU signal (2), GFP signal (3) and their overlay (4) are shown. PfHU is associated with apicoplast DNA and is involved in DNA compaction.Ram EV, Naik R, Ganguli M, Habib S.

Immunofluorescence localisation of PfSufS and PfSufE. (A) Immunofluorescence assay of P. falciparum 3D7 cells using anti-PfSufS Ab with anti-PfHU Ab as apicoplast marker (panel i) or Mitotracker Red (panel ii) indicates targeting of PfSufS to the apicoplast. (B) Co-localisation of PfSufE and apicoplast-targeted GFP observed in the P. falciparum D10 ACPleader-GFP cell line using anti-PfSufE and anti-GFP antibodies (panel i). No overlap of PfSufE signal was observed with Mitotracker Red in P. falciparum 3D7 cells (panel ii) indicating apicoplast localization of PfSufE. PfSufS co-localised with PfHU, an apicoplast DNA condensation protein and no overlapping signals for PfSufS were seen with the mitochondrial marker Mitotracker Red in P. falciparum 3D7 cells (A). PfSufE was localised in the P. falciparum D10-ACPleader-GFP line that targets GFP to the apicoplast. Specific PfSufE signals overlapping with apicoplast-targeted GFP were observed and no overlap of PfSufE signal was seen with Mitotracker Red (B). The localisation of PfSufS and PfSufE exclusively to the apicoplast was thus confirmed.Charan M, Singh N, Kumar B, Srivastava K, Siddiqi MI, Habib S.
