CRISPR-Cas12a offers a convenient tool for multiplex genome editing in rice. However, the CRISPR-Cas12a system displays variable editing efficiency across genomic loci, with marked influence by CRISPR RNAs(crRNAs). To improve the efficiency of the CRISPR-Cas12a system for multiplex genome editing, we identified various architectures and expression strategies for crRNAs. Transformation of binary vectors loaded with engineered CRISPR-Cas12a systems into rice calli and subsequent sequencing reveale...
