A more efficient breeding against plant disease, or the development of new resistant lines, is enabled via the provision of the resistance-mediating gene according to the invention; in particular, a resistance effect in the target plant is evoked by the property of the identified gene. The 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 trans-genetic approaches, with the goal of developing new resistant cultivars.

Gene for resistance to plant disease

The invention relates to plants have a nucleus-encoded, recessive, male sterile phenotype and to the gene locus (gsf) correlating therewith, including the gene which is responsible for the fertile/sterile phenotype and which is mutated in the sterile phenotype. The invention further provides methods for identifying the genotype correlating with the expression of features the plants obtained accordingly to the invention in hybrid breeding and in the production of products obtained from renewable raw materials, such as bioethanol, biogas and sugar-based products.

Nucleus-encoded male sterility through mutation in cytochrome P450 oxidase

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.

Gene conferring resistance toin beets

The invention relates to plants having a nucleus-encoded, recessive, male sterile phenotype and to the gene locus (gst) correlating therewith, including the gene which is responsible for the fertile/sterile phenotype and which is mutated in the sterile phenotype. The invention further provides methods for identifying the genotype correlating with the expression of features indicated above, and the corresponding genetic tools, such as hybridization probes and oligonucleotides. Also described is the use of the plants obtained according to the invention in hybrid breeding and in the production of products obtained from renewable raw materials, such as bioethanol, biogas and sugar-based products.

The invention relates to nucleic acid molecules which impart resistance to rhizomania, in particular to Beet Necrotic Yellow Vein Virus (BNYVV) in a plant, in particular of the genus, and to plants containing such nucleic acid molecules. The invention further relates to methods for producing such BNYVV resistant plants and to marker-based methods for identifying and selecting BNYVV resistant plants, as well as to methods for controlling infection with the pathogen BNYVV.

Resistance gene to rhizomania

A more efficient breeding againstleaf spot disease, or the development of new resistant lines, is enabled via the provision of theresistance-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. Theresistance-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.

The present invention provides a new nucleic acid molecule which encodes a polypeptide that is able to convey a resistance to a pathogen, in particular to 'Beet Necrotic Yellow Vein Virus' in a plant, in particular a plant of thegenus, in which the polypeptide is expressed, and also a preferred nucleic acid molecule encoding the RZ-3 gene of, derivatives and homologues thereof. Further aspects of the invention include vectors, transgenic plant cells, transgenic plants, methods for production thereof, and methods for identifying a resistance-conveying nucleic acid molecule.
