Optimized protoplast isolation and transfection with a breakpoint: accelerating Cas9/sgRNA cleavage efficiency validation in monocot and dicot.

Unlabelled: The CRISPR-Cas genome editing tools are revolutionizing agriculture and basic biology with their simplicity and precision ability to modify target genomic loci. Software-predicted guide RNAs (gRNAs) often fail to induce efficient cleavage at target loci. Many target loci are inaccessible due to complex chromatin structure.
