Fusarium head blight resistant gene Tafhb1 of wheat and use thereof

摘要

A Fusarium head blight (FHB) resistant gene Tafhb1 of wheat and uses thereof are disclosed, in which the FHB resistant gene Tafhb1 of wheat has a cDNA sequence as shown in SEQ ID NO. 1. A protein TaFHB1 encoded by the FHB resistant gene Tafhb1 of wheat has an amino acid sequence as shown in SEQ ID NO. 2. The protein includes 274 amino acids, and has an isoelectric point of 10.85. The FHB resistant gene Tafhb1 of wheat is transferred to wheat by crossing and multiple generations of backcrossing, to increase the resistance of wheat to FHB. Because the gene is an endogenous gene existing in the cereal crop wheat, the presence of the gene has no influence on the food safety of plants, such that the gene can be used in crop breeding.
