摘要
Precise base editing is highly desired in plant functional genomic research and crop molecular breeding. In this study, we constructed a rice-codon optimized adenine base editor (ABE)-nCas9 tool that induced targeted A.T to G.C point mutation of a key single nucleotide polymorphism site in an important agricultural gene. Combined with the modified single-guide RNA variant, our plant ABE tool can efficiently achieve adenine base editing in the rice genome.
