Using CRISPR-Kill for organ specific cell elimination by cleavage of tandem repeats
Abstract
How double strand breaks (DSBs) are repaired within the plant 45S rDNA repeats is unclear. Here, the authors show that Cas9-mediated DSBs in 45S rDNA are mainly repaired by cNHEJ and describe CRISPR-Kill as a tool for organ-specific cell elimination by targeting functional repetitive DNA in Arabidopsis.
