Abstract: Disclosed is a gene for boosting genetic transformation efficiency of wheat and use thereof, which belongs to the field of plant genetic engineering technology. The use of a TaHRF1 gene and an encoded protein thereof can promote integration of an exogenous nucleic acid molecule into a genome of a plant of interest, and boost efficiency of the integration of the nucleic acid molecule, and the transformed plant grows and develops normally. The plant of interest includes, but is not limited to, monocotyledonous plants such as wheat. The present disclosure provides a new and important genetic resource for overcoming the genotype dependence in genetic transformation of wheat.
