CRISPR/Cas9 genome-editing methods are used to reveal functions of genes and molecular mechanisms underlying biological processes in many species, including nematodes. In evolutionary biology, the nematode Pristionchus pacificus is a satellite model and has been used to understand interesting phenomena such as phenotypic plasticity and self-recognition. In P. pacificus, CRISPR/Cas9-mediated mutations are induced by microinjecting a guide RNA (gRNA) and Cas9 protein into the gonads. However, mutant screening is laborious and time-consuming due to the absence of visual markers. In this study, we established a Co-CRISPR strategy by using a dominant roller marker in P. pacificus. We found that heterozygous mutations in Ppa-prl-1 induced the roller phenotype, which can be used as an injection marker. After the co-injection of Ppa-prl-1 gRNA, target gRNA, and the Cas9 protein, roller progeny and their siblings were examined using the heteroduplex mobility assay and DNA sequencing. We found that some of the roller and non-roller siblings had mutations at the target site. We used varying Cas9 concentrations and found that a higher concentration of Cas9 did not increase genome-editing events. The Co-CRISPR strategy promotes the screening for genome-editing events and will facilitate the development of new genome-editing methods in P. pacificus. |
