The invention belongs to the technical field of biology, and particularly relates to a fusion protein AB-NAC and a production method and application thereof. The AB-NAC protein is a fusion body of 59 amino acids (AB fragments) at the HarpinXooN end of xanthomonas oryzae pv. Oryzae and an alpha subunit (NAC) of a neonatal polypeptide related complex, which is derived from Alternaria sp. (Alternaria sp.), and the AB-NAC protein is a fusion body of 59 amino acids (AB fragments) at the HarpinXooN end of the xanthomonas oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv. Oryzae pv The plant immune protein has the functions of AB and NAC at the same time, has the characteristics of bivalent plant immune protein, can stimulate tobacco leaves to generate hypersensitivity (HR), the area of spots is obviously higher than that of AB or NAC, and the effect that 1 + 1 is larger than 2 is achieved. The immunoreaction of plants can be quickly stimulated, t
