Enhancing CRISPR‐Cas12a base editing in plants with LbCas12a variants and introns

Journal of Integrative Plant Biology, EarlyView.
Intron optimization of LbCas12a‐RRV improves cytosine and adenine base editing efficiency in plants, supports multiplexed and double‐strand break‐free genome modification, and expands precise genome engineering tools for crop breeding and plant functional research. ABSTRACT Cytosine base editors (CBEs) and adenine base editors (ABEs) are powerful tools
