Gene conferring resistance to
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.
1. A pelleted seed of a sugar beet plant comprising a nucleic acid molecule encoding a polypeptide that is able to confer resistance to Cercospora beticola in a sugar beet plant in which the polypeptide is expressed, wherein the polypeptide comprises an amino acid sequence that is at least 95% identical to the amino acid sequence according to SEQ ID NO: 3.
2. The pelleted seed of the sugar beet plant according to claim 1 , wherein the pelleted seed of the sugar beet plant is a monogerm seed.
3. The pelleted seed of the sugar beet plant according to claim 1 , wherein the sugar beet plant is harvestable before bolting.
4. The pelleted seed of the sugar beet plant according to claim 1 , wherein the pelleted seed has been polished before pelleting.
5. The pelleted seed of the sugar beet plant according to claim 1 , wherein the pelleted seed has been technically treated, wherein the technical treatment is selected from the group consisting of:
(a) dressing;
(b) incrustation; and
(c) coloring.
6. The pelleted seed of the sugar beet plant according to claim 1 , wherein the pellet comprises at least one chemical selected from the group selected of:
(a) insecticide;
(b) fungicide; and
(c) fertilizer.
7. The pelleted seed of the sugar beet plant according to claim 1 , wherein the seed has been subjected to priming or pre-germination before or during pelleting.
8. The pelleted seed of the sugar beet plant according to claim 1 , wherein the sugar beet plant is a hybrid sugar beet plant.
9. The pelleted seed of the sugar beet plant according to claim 1 , wherein the resistance to Cercospora beticola is dominant.
10. A packing or a bag containing the pelleted seed of the sugar beet plant according to claim 1 .
11. A mixture of a pelleting mass and a sugar beet plant seed wherein the sugar beet plant seed comprises a nucleic acid sequence which encodes a polypeptide that is able to confer resistance to Cercospora beticola in a sugar beet plant in which the polypeptide is expressed, wherein the polypeptide comprises an amino acid sequence that is at least 95% identical to the amino acid sequence according to SEQ ID NO: 3.
12. A method for producing the pelleted seed of the sugar beet plant according to claim 1 comprising the following steps:
I) providing a sugar beet plant seed comprising a nucleic acid sequence which encodes a polypeptide that is able to confer resistance to Cercospora,
wherein the polypeptide comprises an amino acid sequence that is at least 95% identical to the amino acid sequence according to SEQ ID NO: 3
II) embedding the sugar beet plant seed in a pelleting mass
III) allowing the pelleting mass to dry or drying the pelleting mass.
