Phenotype
Asexual blood stage	Not different from wild type
Gametocyte/Gamete	Not different from wild type
Fertilization and ookinete	The mutants developed into ookinetes with normal conversion rates and morphology.
Oocyst	Strongly reduced oocyst production.
Sporozoite	Strongly reduced (salivary gland) sporozoite production.
Liver stage	Not tested
Additional remarks phenotype	Mutant/mutation The mutant lacks expression of CYC3 (cyclin) Protein (function) Phenotype The successful knock-out of cyc3 indicates it has no essential role during blood stage development/multiplication. The mutants developed into ookinetes with normal conversion rates and morphology. Strongly reduced oocyst and sporozoite production. Additional information No differences in DNA contents were observed between wild-type ookinetes and disruptants. Oocysts observed with phasecontrast microscopy were smaller than corresponding wild-type oocysts. The oocyst number of the disruptants was approximately 75% of that of wild-type parasites at 2 dpi and decreased to 20%–30% of that of the wild-type parasites at 14 dpi. The average diameter of the oocysts at this time point was approximately 65% of that of wild-type oocysts. Other mutants
