The application discloses application of NPR1
protein and related
biological materials thereof in regulating resistance of plants to
clubroot disease, and belongs to the technical field of
genetic engineering. The technical problem to be solved by the application is how to regulate resistance of plants to
Plasmodiophora brassicae. Specifically, the technical problem to be solved by the application is how to regulate resistance of cruciferous plants to
Plasmodiophora brassicae. To solve the above technical problem, the application provides application of NPR1
protein or
biological materials related to the NPR1
protein in regulating resistance of plants to
clubroot disease. The application discloses, for the first time, application of NPR1 protein and a coding
gene thereof in regulating resistance of cruciferous plants to
clubroot disease and / or
Plasmodiophora brassicae. Research on the function of NPR1 and application of the function in cruciferous
plant breeding are of great significance to the mechanism of resistance of cruciferous plants to clubroot disease and / or Plasmodiophora brassicae and to resistance breeding.
