Abstract: The present invention relates to a plant comprising a modified Tom2a gene, the wildtype of which comprises SEQ ID No. 1, SEQ ID No. 2, SEQ ID No. 3, SEQ ID No. 4, SEQ ID No. 5, or SEQ ID No. 6, or comprises another homologous sequence having at least 70% sequence identity to SEQ ID No. 1, which modified gene leads to increased resistance to a Tobamovirus. The modification in the Tom2a gene leads to a modified Tom2a protein that has a deletion, a substitution, or an insertion of at least one amino acid when compared to SEQ ID No. 7, SEQ ID No. 8, SEQ ID No. 9, SEQ ID No. 10, SEQ ID No. 11, or SEQ ID No. 12, or compared to another homologous sequence having at least 70% sequence similarity to SEQ ID No. 7. The plant is preferably a plant of the family Cucurbitaceae or Solanaceae. The invention further relates to a modified Tom2a gene encoding a Tom2a protein comprising a deletion, a substitution, or an insertion of at least one amino acid when compared to SEQ ID No. 7, SEQ ID No. 8, SEQ ID No. 9, SEQ ID No.

Abstract: 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.

Abstract: The invention relates to a Solanum lycopersicum plant that is resistant to ToBRFV, which plant comprises a QTL on chromosome 8 between SEQ ID NO: 1 and 4. The presence of the QTL on chromosome 8 is identified by use of at least one of the markers selected from the group consisting of the SNP presented in SEQ ID NOS: 1 to 42. The QTL is present in the genome of a Solanum lycopersicum plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 43637.

Abstract: 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 transfer RNA-like structure (TLS). The invention further relates to plants and seeds comprising the modified genes, methods for making and identifying such plants and use of the gene.

Abstract: The present invention relates to a cultivated melon (Cucumis melo spp. melo) plant resistant against Tomato Leaf Curl New Delhi virus (ToLCNDV), which comprises QTL-1 in its genome, and which QTL-1 confers resistance against Tomato Leaf Curl New Delhi virus (ToLCNDV). The invention further provides progeny, fruit, seeds, propagation material and food products from the plant. The invention also provides markers for the identification of QTL-1, as well as a method for testing a melon (Cucumis melo spp. melo) plant for the presence of QTL-1 in its genome and a method for selecting or identifying a melon plant resistant against ToLCNDV. Also provided is a method for producing a melon (Cucumis melo spp. melo) plant which is resistant against Tomato Leaf Curl New Delhi virus (ToLCNDV).
