Loss of food vacuolar integrity upon fosmidomycin and wortmannin treatment. Shown is the confocal fluorescence microscopic localization of a plasmepsin II-GFP (P2-GFP) construct (left) or live fluorescence imaging of Lysotracker Red-stained malaria parasites (right). Control parasites (A) are compared to parasites treated for 24 h with either fosmidomycin (B), fosmidomycin plus geranylgeraniol (C), or wortmannin (D). Images are representative of at least three independent biological experiments. Visualization of PMIIGFP in FSM- and wortmannin-treated parasites required higher detector gain levels, resulting in increased observed erythrocyte autofluorescence. Lower panel: Apicoplast and parasitophorous vacuolar targeting in fosmidomycin- and wortmannin-treated parasites. Shown is live-cell fluorescence of malaria parasites that express either the leader sequence (ACPL-GFP) (A) or signal sequence (ACPs-GFP) (B) from P. falciparum acyl carrier protein, fused to GFP, which traffic to the apicoplast or parasitophorous vacuole, respectively. Untreated parasites (control) are compared to fosmidomycin (FSM)- and wortmannin (wort)-treated parasites. Images are representative of at least three independent biological experiments.
