  • Publication number: 20220361429
    Abstract: The present invention relates to a modified FBXL13 gene which leads to a plant showing resistance to a virus belonging to the Torradovirus genus. The invention also relates to a plant belonging to the Solanaceae family comprising the modified FBXL13 gene. The modified FBXL13 gene of the invention provides a plant showing resistance to a virus belonging to the Torradovirus genus when compared to plants not comprising the modified FBXL13 gene. The invention further relates to the use of the modified FBXL13 gene for the identification and development of a plant belonging to the Solanaceae family showing resistance to a virus belonging to the Torradovirus genus.

  • Patent number: 11497189
    Abstract: The present invention relates to a tomato plant (Solanum lycopersicum L.) which may comprise a genetic determinant that confers resistance to Pepino Mosaic Virus (PepMV), wherein the resistance is characterised by the presence of at least QTL1 and/or QTL2. The invention also relates to sources for obtaining said genetic determinant, representative seed of which were deposited with the NCIMB under accession numbers NCIMB 41927, NCIMB 41928, NCIMB 42068, and NCIMB 42069. The invention further relates to seeds and progeny of the plant and to its fruits and processed fruits. In addition the invention relates to molecular markers linked to PepMV resistance conferring QTLs and the use thereof.

  • Patent number: 9241455
    Abstract: The present invention relates to a tomato plant (Solanum lycopersicum L.) in which the glandular heads of type VI trichomes are absent, and that has a modified composition of flavonoids and volatiles. Furthermore, the typical tomato smell is absent or nearly absent. The plant comprises a mutant allele, which is obtainable from a tomato plant, representative seed of which was deposited under deposit accession number NCIMB 41845. The said mutant allele is located on chromosome 9 between positions 1750800 bp and 4517648 bp, preferably between positions 1939546 bp and 2970346 bp, most preferably at about position 2454946 bp on a physical map of the Solanum lycopersicum genome.
