Epigenetic editing by CRISPR/dCas9 in Plasmodium falciparum.

ABSTRACT: Genetic manipulation remains a major obstacle for understanding the functional genomics of the deadliest malaria parasite Plasmodium falciparum Although the CRISPR/Cas9 (clustered regularly interspaced short palindromic repeat/CRISPR-associated protein 9) system has been successfully applied to introduce permanent changes in the parasite genome, its use is still limited. Here we show that fusing different epigenetic effector domains to a Cas9 null mutant efficiently and specifically reprograms the expression of target genes in P. falciparum By precisely writing and erasing histone acetylation at the transcription start site regions of the invasion-related genes reticulocyte binding protein homolog 4 (rh4) and erythrocyte binding protein 175 (eba-175
