Changing local recombination patterns in Arabidopsis by CRISPR/Cas mediated chromosome engineering
Abstract
The heterochromatic knob (hk4S) on Arabidopsis chromosome 4 prevents the recombination between accessions with and without hk4S. Here, via egg-cell specific expression of the Cas9 nuclease, the authors demonstrate targeted reversal of the 1.1 Mb long hk4S-inversion in Col-0 and restore the crossovers with Ler-1.
