Selection (positive) procedurepyrimethamine
Selection (negative) procedureNo
Additional remarks genetic modificationDisruption experiments were performed in the Leiden Malaria Research Group (exp. 586, 613; pl1030).

A P. falciparum mutant lacking expression of glycerol kinase has been generated (Schnick C. et al., 2009; Mol. Microbiol. 71:533-45). Deletion of the glycerol kinase gene from P. falciparum had no effect on asexual parasite growth, gametocyte development and exflagellation of male gametocytes.
