Abstract: Protozoa have complex life cycle and most of them can not complete the life cycle just in vitro. As a result, most of them lack an effective gene editing system. The CRISPR (clustered regularly interspaced short palindromic repeat)/Cas9 (endonuclease) system facilitates the precise, efficient, and rapid genetic editing through homologous recombination, and is widely used in genetic modification of eukaryotic organisms. The CRISPR/Cas9 system opens up a new avenue for targeted investigation of gene functions in protozoans. This article introduces the principle of the CRISPR/Cas9 system and its major applications in gene tagging and depletion and genome-wide screening of functional gene families in parasitic protozoan.

Key words: CRISPR/Cas9, genetic editing, parasite, protozoa
