Toolkit plasmids for efficient integration of DiCre recombinase into p230p or pfs47 loci of the P. falciparum genome. The CRISPR-Cas9 plasmid used here, pDC2-Cas9-hDHFRyFCU (derived from pDC2-Cas9-U6-hdhfr 27) carries the SpCas9 nuclease gene and a single guide RNA cassette driven by a short U6 promoter and the hdhfr-yfcu fusion gene for selection. The rescue plasmids (pBSp230pDiCre and pBSPfs47DiCre) contain the genes for the split Cre-recombinase fused to FRB and FKBP12 respectively, flanked by regions of homology from the p230p or the pfs47 locus of P. falciparum. More detailed vector maps are available in Supplementary Fig. S2.
