Phenotype
Asexual blood stage	GFP-Luciferase expression in mature schizonts and young ring forms.
Gametocyte/Gamete	Not different from wild type
Fertilization and ookinete	Not tested
Oocyst	GFP-Luciferase expression in maturing (late-stage) oocysts
Sporozoite	GFP-Luciferase expression in salivary gland sporozoites
Liver stage	GFP-Luciferase expression in maturing liver stages (liver merozoites)
Additional remarks phenotype	Mutant/mutation The mutant expresses GFP-luciferase under the control of the schizont-specific ama-1 promoter. Phenotype GFP-Luciferase is expressed in maturing schizonts and is still present in young ringforms (0-4 hours after invasion), carried over from the schizonts. No expression of GFP-luciferase in gametocytes/gametes. Unpublished observations: GFP-Luciferase expression in maturing (late-stage) oocysts. (Relatively strong) GFP-Luciferase expression in salivary gland sporozoites and GFP-Luciferase expression in maturing liver stages (liver merozoites). Additional information This mutant has been used to analyse CD36-mediated sequestration of the schizont stage of P. berghei in live animals (or in isolated organs) by real time in vivo imaging (by measurement of bioluminescence) (Franke-Fayard et al., 2005, Proc Natl Sci USA, 102, 11468-73). These studies indicate that the schizont of P. berghei mainly sequester/accumulate in small capillaries of adipose tissue, lungs and the spleen. In comparison with mutants expressing only GFP under the same promoter (ama1 promoter), the GFP-fluorescence intensity of this reporter mutant is lower as a result of the GFP-Luciferase fusion. This mutant does not contain a drug-selectable marker. This mutant, which has been selected by FACS sorting (based on GFP-fluorescence), can therefore be used for the introduction of additional genetic modifications using vectors that contain drug-selectable markers. This mutant is used for in vitro antimalarial drug screening in mice using the ITDL assay (Franke-Fayard et al., 2008, Int. J. Parasitol. 38, 1651-62). The in vitro drug luminescence (ITDL) assay, measured the success of schizont maturation in the presence of candidate drugs quantifying luciferase activity in mature schizonts only (ama-1 promoter). The ITDL assay generated drug-inhibition curves and EC(50) values comparable to those obtained with standard in vitro drug-susceptibility assays. See also the luciferase expressing mutant RMgm-29 which is used for in vivo antimalarial drug screening. Other mutants Mutant RMgm-30 expressing GFP-Luciferase under the control of the ama-1 promoter containing a drug selectable marker (the pyrimethamine resistant tg-dhfr gene).

Restriction sites to linearize plasmid KspI (SacII)

Selectable marker used to select the mutant parasite gfp (FACS)

Promoter of the selectable marker ama-1

Selection (positive) procedure FACS (flowsorting)

Selection (negative) procedure No

Additional remarks genetic modification The GFP-Luciferase gene (1 copy) has been inserted into the 230p locus (PB000214.00.0) by double cross-over integration.

Additional remarks selection procedure This reporter mutant expressing GFP-Luciferase does not contain a drug-selectable marker. This mutant has been selected by FACS sorting after transfection based on GFP fluorescence.
