Abstract excerpt

Grain Width and Weight 2 (GW2) is an E3-ubiquitin ligase-encoding gene that negatively regulates the size and weight of the grain in cereal species. Therefore, disabling GW2 gene activity was suggested for enhancing crop productivity. We show here that CRISPR/Cas-mediated mutagenesis of the barley GW2.1 homologue results in the development of elongated grains and increased protein content. At the same time, GW2.1...
