The invention discloses a promoter quick cloning method. In the method, two grape pathogen inducible promoters are obtained by cloning to construct a promoter:: a reporter gene fused vector, wherein expression of two promoter start reporter genes in grape leaves is induced by blumeria graminis, thus the method provides a pathogen inducible promoter cloning method for the grape disease resistance gene engineering and successfully applies the pathogen inducible promoter to breeding for disease resistance of grapes. Both the two cloned inducible promoters can accurately regulate exogenous genes when pathogen invades, so that the exogenous genes can be promoted to express only under a pathogen induced condition; in the breeding for disease resistance of grape, only the reporter gene promoted by the promoter in recombinant vector is converted into an arbitrary disease resistance gene, so that the grape can be converted into a transgenic plant with pathogen induced expression exogenous disease resistance gene, the adverse influence of a constitutive promoter on transgenic grape in the breeding of disease resistance gene engineering can be reduced, and the advantage of transgenic grape can be played to the greatest extent.
