Forward and reverse genetic approaches have been well developed in the nematode Caenorhabditis elegans; however, efficient genetic tools to generate conditional gene mutations are still in high demand. Recently, the Clustered Regularly Interspaced Short Palindromic Repeats/CRISPR-associated protein 9 (CRISPR-Cas9) system for genome modification has provided an additional tool for C. elegans researchers to achieve simple and efficient conditional targeted mutagenesis. Here, we review recent advances in the somatic expression of Cas9 endonuclease for conditional gene editing. We present some practical considerations for improving the efficiency and reducing the off-target effects of somatic CRISPR-Cas9 and highlight a strategy to analyze somatic mutation at single-cell resolution. Finally, we outline future applications and consider challenges for this emerging genome editing platform that will need to be addressed in the future.
