Fecha de publicación: -- Fuente: WIPO "tomato" The present disclosure provides methods of inserting a polynucleotide of interest into the genome of a eukaryotic cell, wherein said methods comprise improving the efficiency of CRISPR/Cas-mediated polynucleotide insertion by addition of an inhibitor of the microhomology—mediated end-joining (MMEJ) pathway to the eukaryotic cell. The present disclosure further provides compositions for inserting a polynucleotide of interest into the genome of a eukaryotic cell, and kits for inserting a gene of interest into the genome of a eukaryotic cell.
