A method for determining gene expression in transgenic plants is disclosed. This method includes providing expression vectors having the PAP1 or PAP2 gene linked to an expressed gene of interest. If the expression vector is activated, the PAP1 or PAP2 genes confer a purple pigmentation to the transgenic plant. Thus, plants that have been successfully transformed are easily identifiable by visual inspection.

Regulation of anthocyanin pigment production

Substantially purified CDR1 polypeptide, isolated polynucleotides encoding CDR1 polypeptide, vectors containing CDR1, host cells expressing CDR1, and antibodies which bind to CDR1 are all provided. The invention also provides a method of producing a genetically modified plant characterized as having increased disease resistance as compared to wild-type plants. A method is also provided for identifying novel disease resistance genes by probing a nucleic acid library with at least a fragment of a polynucleotide encoding CDR1, and selecting those clones that hybridize with the fragment.
