Abstract: Clustered regularly interspaced short palindromic repeats (CRISPR) / CRISPR-related protein (Cas) system is a heritable prokaryotic adaptive immune system against invading nucleic acids. It is an editing tool for many organisms that can generate highly specific gene double-strand breaks and repair them by non-homologous end joining (NHEJ) or homologous recombination (HR). Due to the complexity of its genetic manipulation, Mycobacterium tuberculosis genome research has many difficulties. Therefore, the emergence of the CRISPR/Cas system has a milestone significance for the research of Mycobacterium tuberculosis. In this review, we focus on the application of the CRISPR/Cas system in Mycobacterium tuberculosis and summarizes the present research progress in order to provide a reference for the selection of Mycobacterium tuberculosis research methods.

Key words: Mycobacterium tuberculosis, CRISPR/Cas system, CRISPR/dCas9, CRISPR-Cas12a
