    Genome editing (GE) has revolutionized biological research through the new ability to precisely edit the genomes of living organisms. In recent years, various GE tools have been explored for editing simple and complex genomes. The clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 system has widely been used in GE due to its high efficiency, ease of use, and accuracy. It can be used to add desirable and remove undesirable alleles simultaneously in a single event. Here, we discuss various applications of CRISPR/Cas9 in a range of important crops, compare it with other GE tools, and review its mechanism, limitations, and future possibilities. Various newly emerging CRISPR/Cas systems, including base editing (BE), xCas9, and Cas12a (Cpf1), are also considered.
