Parent parasite used to introduce the genetic modification | |
Rodent Malaria Parasite | P. berghei |
Parent strain/line | P. berghei ANKA |
Name parent line/clone | P. berghei ANKA 676m1cl1 (RMgm-29) |
Other information parent line | 676m1cl1 (RMgm-29) is a reference ANKA mutant line which expresses GFP-luciferase under control of a constitutive promoter. This reference line does not contain a drug-selectable marker (PubMed: PMID: 16242190). |

Phenotype | |
Asexual blood stage | Not different from wild type |
Gametocyte/Gamete | No gametocyte production |
Fertilization and ookinete | No ookinete production |
Oocyst | Not tested |
Sporozoite | Not tested |
