Details of the genetic modification
Inducable system usedNo
Additional remarks inducable system To express YFP and luciferase in P. berghei ANKA, construct encoding YFP and luciferase fusion protein (YFPluc) were cloned into the plasmid vector pSK-1-cssu (Niikura et al., 2013), which contains a selectable marker cassette encoding human dihydrofolate reductase (hdhfr) under control of the elongation factor 1 α (ef-1α) promoter, a GFP expression cassette under the control of the P. berghei heat shock protein 70-1 (hsp70-1) promoter, and homology arms of the cssu/dssu ribosomal gene locus of P. berghei. pSK-1-cssu was digested with NheI and BglII; therefore, GFP was removed. Subsequently, the YFPluc fragment was cloned into the NheI and BglII site of pSK-1-cssu. To obtain the P. berghei YFPluc, transfection was done by electroporation using the Amaxa nucleofector kit. The mutant parasites were selected by pyrimethamine for 2 wk, and then a clonal line expressing YFP and luciferase was obtained by limiting dilution.
