Abstract

A more efficient breeding against Cercospora leaf spot disease, or the development of new resistant lines, is enabled via the provision of the Cercospora resistance-mediating gene according to the invention; in particular, a dominant resistance effect in the target plant is evoked by the property of the identified gene alone. The Cercospora resistance-mediating gene, and embodiments of the present invention that are described in the preceding, offer additional applications, e.g., the use of the resistant gene allele in cis-genetic or trans-genetic approaches, with the goal of developing new resistant cultivars.

Claims (19)

a nucleic acid molecule encoding a polypeptide that is able to confer resistance to Cercospora beticola in a plant in which the polypeptide is expressed, wherein the nucleic acid molecule comprises a nucleotide sequence that encodes a polypeptide having the amino acid sequence according to SEQ ID NO:3; and

a promoter comprising SEQ ID NO:7.

2 . The plant or portion thereof according to claim 1 , wherein the plant is a hybrid plant.

14 . The plant or portion thereof according to claim 9 , wherein the nucleic acid molecule positioned between the markers comprise confers the Cercospora beticola resistant genotype.

15 . The plant or portion thereof according to claim 14 , wherein the markers are selected from the group consisting of SEQ ID NOs: 55, 57, 59, 61, 63, and 65.

16 . A storage organ of the plant according to claim 1 , wherein the storage organ comprises the nucleic acid molecule.
