Generation of early-flowering Chinese cabbage (Brassica rapa spp. pekinensis) through CRISPR/Cas9-mediated genome editing

The CRISPR system enables us to induce precisely targeted mutations in a plant genome. The widely used CRISPR system is composed of a Cas9 protein derived from Streptococcus pyogenes (SpCas9) and a target site-specific guide RNA. In this study, we successfully generated the early-flowering Chinese cabbage (Brassica rapa spp. pekinensis), which is one of the most important vegetables in the world. To generate early-flowering B. rapa without...
