  • Patent number: 12376537
    Abstract: The invention relates to a Solanum lycopersicum plant that is resistant to TBRFV, which plant comprises a QTL on chromosome 11 between SEQ ID NO: 1 and 53. The presence of the QTL on chromosome 11 is identified by use of at least one of the markers selected from the group comprising SEQ ID NOS: 4 to 52. The QTL is as comprised in the genome of a Solanum lycopersicum plant representative seed of which was deposited with the NCIMB under deposit number NCIMB 42882, NCIMB 42885, NCIMB 42887, or NCIMB 42890.

  • Publication number: 20250008903
    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.

  • Publication number: 20240237606
    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.

  • Publication number: 20230284587
    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.
