Targeted base editing in plants without the need for a foreign DNA donor or double-stranded DNA cleavage would accelerate genome modification and breeding in a wide array of crops. We used a CRISPR-Cas9 nickase-cytidine deaminase fusion to achieve targeted conversion of cytosine to thymine from position 3 to 9 within the protospacer in both protoplasts and regenerated rice, wheat and maize plants at frequencies of up to 43.48%.
