Restriction sites to linearize plasmid
Partial or complete disruption of the geneUnknown
Additional remarks partial/complete disruption
Selectable marker used to select the mutant parasiteunknown
Promoter of the selectable markerunknown
Selection (positive) procedureunknown
Selection (negative) procedureNo
Additional remarks genetic modificationAttempts to disrupt the pbsub1 gene in P. berghei blood stages failed (S. Yeoh, R. Tewari, O. Billker and M. Blackman, unpublished), suggesting that PbSUB1 too is indispensable in the erythrocytic parasite life cycle.
No details of the unsuccessful attempts are provided.
See RMgm-952 and RMgm-973 for conditional knock-out mutants of SUB1 (mutants that lack expression of SUB1 in liver stages)
