Additional remarks genetic modification | Published in: bioRxiv preprint doi: https://doi.org/10.1101/2021.10.29.466443 The unsuccessful attempts to disrupt this gene indicate an essential function during asexual blood stage growth/multiplication. The PbDDI1 gene was targeted for knock-out and knock-down using double cross-over homologous recombination approach. For the knock-out constructs, the 5'-UTR (flank 1) and 3’-UTR (flank 2) of PbDDI1 were amplified from P. berghei genomic DNA using PbDdi1- Fl1F/ PbDdi1-Fl1R and PbDdi1-Fl2F/PbDdi1-Fl2R primer sets, respectively. The flank 1 and flank 2 were cloned into the HB-DJ1KO plasmid at NotI-KpnI and AvrII-KasI sites, respectively, to obtain HB-PbDDI-(FL1+FL2) plasmid. The GFP coding sequence was excised from pGT-GFPbsc with KpnI-XhoI and subcloned into the similarly digested HB-PbDDI- (FL1+FL2) to obtain HB-pbDDIKO plasmid. | ||||||||||||||||||||||||
