One-step genome editing of elite crop germplasm during haploid induction

Genome editing using CRISPR-Cas9 works efficiently in plant cells1, but delivery of genome-editing machinery into the vast majority of crop varieties is not possible using established methods2. We co-opted the aberrant reproductive process of haploid induction (HI)3-6 to induce edits in nascent seeds of diverse monocot and dicot species. Our method, named HI-Edit, enables direct genomic modification of commercial crop varieties. HI-Edit was...
