Corn plants exhibiting resistance to Head Smut disease are provided, together with methods of producing, identifying, or selecting plants or germplasm with a Head Smut resistance phenotype. Such methods include producing a corn plant exhibiting resistance to HS, comprising introgressing genomic regions conferring disease resistance; or selecting a corn plant exhibiting resistance to HS. Compositions, including polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.

The present invention relates to new transporter polypeptides, and genes encoding therefor, which can be used to confer upon a plant resistance to one or more biotrophic fungal pathogens.

Corn plants exhibiting broad-spectrum resistance to Exserohilum turcicum are provided, together with methods of producing, identifying, or selecting plants or germplasm with a Exserohilum turcicum resistance phenotype. Such plants include sweet corn plants as well as agronomically elite dent corn plants comprising introgressed genomic regions conferring disease resistance. Compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are further provided.

Provided herein are Apium graveolens plants resistant to the plant pathogen Fusarium oxysporum f. sp. Apii race 4 and wherein the resistance is encoded by one genomic region or a combination of at least two, or three genomic regions. Also provided herein are methods for identifying the present Fusarium oxysporum f. sp. Apii race 4 resistant plants and to molecular markers for use in the present methods.

Tomato plants exhibiting resistance to tomato chlorosis virus and Fusarium oxysporum f. sp. lycopersici race 2 are provided, together with methods of producing, identifying, or selecting plants or germplasm with a tomato chlorosis virus and Fusarium oxysporum f. sp. lycopersici race 2 resistance phenotype and lacking an undesirable cold sensitivity trait. Such plants include tomato plants comprising recombinant genomic regions conferring disease resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.

Provided herein are Beta vulgaris plants resistant to Cercospora. Also provided herein are methods for identifying Cercospora resistant Beta vulgaris plants, methods for providing Cercospora resistant Beta vulgaris plants and means for identifying Cercospora resistant Beta vulgaris plants. Specifically, provided herein are Cercospora-resistant Beta vulgaris plants including a first Cercospora resistance providing genomic fragment on chromosome 4, wherein said first Cercospora resistance providing genomic fragment includes at least one sequence from the group consisting of SEQ ID Nos. 1, 3, 5, 7, 9, 11, 13, and 15.

The present invention provides methods and compositions for producing elite lines of corn exhibiting improved resistance to TARSC. Also provided in the present invention are corn plants exhibiting TARSC resistance resulting from such methods, and methods for breeding corn such that the TARSC resistance traits may be transferred to a desired genetic background.

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.

The present invention relates to maize plants having increased pathogen resistance or tolerance, in particular increased resistance or tolerance to pathogens causing Northern Corn Leaf Blight, i.e. Exserohilum turcicum. Such maize plants can be characterized as having a particular QTL allele comprising one or more resistance gene, or particular molecular markers The invention further relates to methods for generating such maize plants, as well as methods for identifying such maize plants.

The invention relates to a Brassica plant that is resistant to Hyaloperonospora brassicae, which plant may comprise a QTL on chromosome 8, and optionally a QTL on chromosome 4, and/or a QTL on chromosome 1. The presence of the QTL on chromosome 8 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 1 to 7; the presence of the QTL on chromosome 4 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 8 to 16; and the presence of the QTL on chromosome 1 can be identified by use of at least one of the markers selected from the group consisting of SEQ ID NOS: 17 to 22. The QTL is as comprised in the genome of a Brassica plant representative seed of which was deposited with the NCIMB under accession number NCIMB 43346.
