The present invention provides transgenic, disease-resistant plants which have been transformed with an expression cassette including a constitutive gene expression promoter; and a gene, under the control of the promoter, encoding a harpin. The transformed cells in the transgenic plant effect the constitutive expression of the harpin in an amount effective for inducing a defense reaction. The harpin is a protein consisting of an amino acid sequence that is at least 90% homologous to the amino acid sequence of SEQ ID NO: 2, and possesses a hypersensitive-response-inducing activity. The present invention also provides methods for producing the transgenic plants, expression cassettes, recombinant vectors and genes encoding harpins.

Disease-resistant plants and method of constructing the same

It is the object of the present invention to provide disease-resistant plants which have been transformed to cause an effective defense reaction, and methods for producing the same. The present invention provides expression cassettes comprising a promoter capable of promoting a constitutive, inducible, or organ- or phase-specific gene expression, and a gene, under the control of said promoter, encoding an elicitor protein.
