The invention provides a Tomato Leaf Curl New Dehli Virus (ToLCNDV) tolerance or resistant QTL in cucurbit plants and plants comprising the QTL. The invention also provides molecular markers linked to QTL. The invention further provides methods of breeding to produce plants that are resistant to ToLCNDV, and the resistant plants produced by such methods.

The present application relates to papaya plants having increased resistance to the papaya ringspot virus as compared to a wild type plant due to a mutation in the eukaryotic translation initiation factor 4e and/or eukaryotic translation initiation factor iso4e gene leading to non-functional eukaryotic translation initiation factor 4e and/or eukaryotic translation initiation factor iso4e proteins. Methods of producing such papaya plants having increased resistance to the papaya ringspot virus are described.

The present invention relates to a modified CCA gene which encodes a CCA-adding enzyme, which modified CCA gene leads to resistance against a positive-strand RNA virus having a TLS, wherein the modified CCA gene comprises a gene comprising a nucleotide sequence that encodes a CCA-adding enzyme, a gene comprising a promoter sequence, or a gene comprising a nucleotide sequence that encodes a CCA-adding enzyme having a deletion, a substitution, or an insertion of at least one amino acid. The invention further relates to plants and seeds comprising the modified genes, methods for making and identifying such plants and use of the gene.

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.

The present invention relates to plants comprising in their genome a gene that has been inactivated rendering the plant resistant to Pepino mosaic virus (PepMV) infection. The present invention also refers to the inactivation of the gene required for PepMV infection. The invention encompasses parts of these plants and their progeny that show said gene inactivation and as a consequence an improved phenotype in terms of PepMV infection resistance. Methods for obtaining plants, or plant parts or seeds with resistance to PepMV infection are also part of this invention. The present invention further relates to the gene and sequences linked to it as markers for selecting plants resistant to PepMV infection. Therefore, the present invention belongs to the field of agriculture.

The invention provides a Tomato Leaf Curl New Delhi Virus (ToLCNDV) tolerance or resistant QTL in cucurbit plants and plants comprising the QTL. The invention also provides molecular markers linked to QTL. The invention further provides methods of breeding to produce plants that are resistant to ToLCNDV, and the resistant plants produced by such methods.

Provided are expression cassettes that can be used to express proteins in plants. In some embodiments, the expression cassettes include polynucleotides that encode polypeptides that are at least 96% identical to SEQ ID NO: 2 operably linked to a promoter and a transcription terminator and optionally a tag sequence. Also provided are recombinant vectors, cells, and transgenic plants, progeny, and seeds that include the presently disclosed expression cassettes, and methods for using the disclosed expression cassettes to alter geminivirus resistance and suppress virus-induced leaf chlorosis, leaf curling, or both in plants.

The application relates to the field of plant breeding, in particular watermelon breeding. Provided are CVYV resistant watermelon plants (and seeds from which these plants can be grown). Also provided is a QTL for CVYV resistance (cyv_3.1) and markers and methods for screening plants for the presence of the QTL.

Methods of producing a tomato plant exhibiting tolerance or resistance to ToBRFV are provided. Also provided are methods of identifying such plants and plants derived thereby as well as processed products comprising same.

The present invention relates to a hybrid Solanum lycopersicum plant comprising in its genome at least one copy of the Rug-1 resistance gene, wherein said Rug-1 resistance gene is capable of conferring a Tomato Brown Rugose Fruit Virus (ToBRFV) tolerance/resistance phenotype. The present invention further relates to a seed produced by the plant according to the present invention, a seed from which a plant according to present invention can be grown, a fruit produced by a plant according to the present invention and a part of a plant according to the present invention. The present invention further relates to a method of identifying and/or selecting a plant or plant part according to the present invention. The present invention further relates to a method for producing a Solanum lycopersicum plant having a ToBRFV tolerance/resistance phenotype according to the present invention. The present invention further relates to a method for enhancing the ToBRFV tolerance/resistance phenotype of a Solanum lycopersicum plant, the use of the Rug-1 resistance gene according to the present invention for enhancing the ToBRFV tolerance/resistance phenotype in a Solanum lycopersicum plant and the use of a genetic marker specific of the Rug-1 resistance gene according to the present invention for selecting a Solanum lycopersicum plant having an enhanced ToBRFV tolerance/resistance phenotype.
