Construction of CRISPR/Cas9 Multiplex Genome Editing System in Rice

Multiplex genome editing (MGE) technologies constitute essential tools for rapid genome modification of multiple targets in one gene or multiple genes simultaneously. However, the vector construction process is complicated, and the number of mutation targets is constrained using the conventional binary vectors. Here, we describe a simple CRISPR/Cas9 MGE system based on classical isocaudomer technique in rice, which is comprised of only two simple vectors, and can theoretically be used to edit an unlimited number of genes simultaneously.
