Phenotype
Asexual blood stageGFP expression in all stages except for male gametes; Increase of GFP expression during development from ring form into mature trophozoite/immature schizont; decrease of GFP expression in mature schizonts. Strong GFP-expression in female gametocytes.
Gametocyte/GameteGFP expression in female and male gametocytes. Strong GFP-expression in female gametocytes. Higher expression in females, compared to males.
Fertilization and ookineteGFP expression in ookinetes.
OocystGFP expression in oocysts.
SporozoiteGFP expression in sporozoites.
Liver stageGFP expression during liver stage development.
Additional remarks phenotype

Mutant/mutation
The mutant expresses GFP under the control of the constitutive promoter of the elongation factor 1 alpha (eef1a) gene of P. berghei.

Phenotype
GFP is expressed in all life cycle stages and expression of the transgene has no influence on parasite viability and infectivity.

Additional information
This mutant is widely used in studies using visualisation of parasites and FACS analysis of infection.
This reporter mutant does not contain a drug-selectable marker. This mutant, that has been selected by FACS sorting, can therefore be used for the introduction of additional genetic modifications using vectors that contain drug-selectable markers.

Other mutants
A reporter mutant (RMgm-5) expressing GFP under the control of the eefa promoter exists that contains a drug selectable marker (the pyrimethamine resistant tgdhfr gene).
