ABSTRACT:
The present invention relates to a method for down regulating anArabidopsisprotein phosphatase type 2C gene, referred to as “defense-associated protein phosphatase type 2C one” (DAPP1) that functions as a negative regulator of a plant defense pathway by contacting the gene or gene mRNA with an interfering nucleotide sequence that interacts with the gene and reducing expression thereof. Plants including such interfering nucleotide sequence exhibit increased disease resistance to pathogen even in the absence of R genes. Close homologs of DAPP1 exist in multiple crop species, and as such, the controlled down-regulation of homologous genes in a variety of crop species will enhance disease resistance of target crop species to pathogens.
