Abstract
Prime editing, a CRISPR-Cas9-derived precise genome editing strategy, was recently developed to introduce targeted indels and all 12 types of point mutations without DNA double-strand breaks or donor DNA. The prime editing systems have been adopted for precision genome editing in crops including rice, wheat, maize, and tomato, which substantially expands the scope and capabilities of precision plant breeding. Here, we describe a fast and efficient method for construction of prime editing vectors based on Gateway assembly and efficiency assessment of prime editors through transient expression analyses in rice protoplasts.
