The potential of genome editing to improve the agronomic performance of crops is often limited by low plant regeneration efficiencies and few transformable genotypes. Here, we show that expression of a fusion protein combining wheat GROWTH-REGULATING FACTOR 4 (GRF4) and its cofactor GRF-INTERACTING FACTOR 1 (GIF1) substantially increases the efficiency and speed of regeneration in wheat, triticale and rice and increases the number of transformable wheat genotypes. GRF4-GIF1 transgenic plants were fertile and without obvious developmental defects. Moreover, GRF4-GIF1 induced efficient wheat regeneration in the absence of exogenous cytokinins, which facilitates selection of transgenic plants without selectable markers. We also combined GRF4-GIF1 with CRISPR-Cas9 genome editing and generated 30 edited wheat plants with disruptions in the gene Q (AP2L-A5). Finally, we show that a dicot GRF-GIF chimera improves regeneration efficiency in citrus, suggesting that this strategy can be applied to dicot crops.
