Name of the mutant parasite | |
RMgm number | RMgm-628 |
Principal name | 1964 |
Alternative name | RON4::mCherry |
Standardized name | |
Is the mutant parasite cloned after genetic modification | No |
top of page | |
Phenotype | |
Asexual blood stage | Schizonts express mCherry-tagged RON4 as shown by fluorescence microscopy. Merozoites of mature schizonts show a 'rhoptry-like' fluorescence pattern (see also 'Additional remarks phenotype'). |
Gametocyte/Gamete | Not tested |
Fertilization and ookinete | Not tested |
Oocyst | Not tested |
Sporozoite | RON4::mCherry expression in sporozoites |
Liver stage | Not tested |
Additional remarks phenotype | Mutant/mutation The mutant has been (described and) used to analyse sporozoite migration in hepatocytes (Published in PMID: 32979009) Additional information

Additional remarks genetic modification | To generate the transgenic RON4-mCherry, parasites expressing C-terminally tagged mCherry RON4 (PBANKA_932000), construct pL1577 was used (Fougere et al., 2016). The smac (PBANKA_0100600) was exchanged for the ron4 targeting region amplified with primers 6686 and 6687 (5’- gggactagtGCATCCATATTAATGCAACAATGG and 5’- cccggatccTAAATCATCAAAAATGGCTTTCTC) using restriction sites, SpeI/BamHI. Tranfection (exp. 1964; RMgm-628; www.pberghei.eu) of the linearized pL1837 plasmid (using NdeI), selection and cloning of transformed parasites was performed using standard genetic modification technologies | ||||||||||||||||||||||||||
