Prime editors, which are CRISPR-Cas9 nickase (H840A)-reverse transcriptase fusions programmed with prime editing guide RNAs (pegRNAs), can edit bases in mammalian cells without donor DNA or double-strand breaks. We adapted prime editors for use in plants through codon, promoter, and editing-condition optimization. The resulting suite of plant prime editors enable point mutations, insertions and deletions in rice and wheat protoplasts. Regenerated prime-edited rice plants were obtained at frequencies of up to 21.8%.

水稻和小麦的 Prime 基因组编辑。

Prime 编辑器是 CRISPR-Cas9 切口酶 (H840A)-逆转录酶融合体,使用 prime editing guide RNA (pegRNA) 进行编程,可以在没有供体 DNA 或双链断裂的情况下编辑哺乳动物细胞中的碱基。我们通过密码子、启动子和编辑条件优化来调整用于植物的主要编辑器。由此产生的植物初级编辑器套件可以在水稻和小麦原生质体中实现点突变、插入和缺失。再生的 prime-edited 水稻植物以高达 21.8% 的频率获得。
