Efficient gene disruption in polyploid genome by Cas9-Trex2 fusion protein

J Integr Plant Biol. 2024 Oct 25. doi: 10.1111/jipb.13797. Online ahead of print.

Abstract

The fusion of the exonuclease Trex2 with the Cas9 protein significantly enhanced the efficiency of genome editing in hexaploid common wheat, particularly for the simultaneous editing of multiple favorable alleles within a single generation, thereby facilitating genome editing-assisted breeding in polyploid crops.

Keywords: CRISPR/Cas9; Trex2; exonuclease; multiplex genome editing; wheat.
