ABSTRACT:
A mutant gene coding for pectate lyase and homologs thereof is provided, which when incorporated in transgenic plants effect an increased level disease resistance in such plants. Also is provided the polypeptide sequence for the pectate lyase of the present invention. Methods of obtaining the mutant gene, producing transgenic plants which include the nucleotide sequence for the mutant gene and producing improved disease resistance in a crop of such transgenic plants are also provided.
