摘要
Dear Editor The newly developed CRISPR/Cas9-mediated base editing technology with cytosine deaminase is capable of precisely and efficiently introducing point mutations at the target genomic locus, which does not require double-stranded DNA breaks or any donor templates and thus exhibit a great potential for gene correction and genetic diversification in yeasts, plants, and mammalian and human cells （Komor et al., 2016; Nishida et al., 2016; Lu and Zhu, 2017; Ren et al., 2017）.
