  • Publication number: 20090126037
    Abstract: The present invention relates to a method for detecting a quantitative trait locus (QTL) associated with resistance to Botrytis cinerea in tomato, comprising the steps of crossing a Botrytis-resistant donor tomato plant with a non-resistant, or Botrytis-susceptible, recipient tomato plant, contacting one or more offspring plants with an infective amount of Botrytis, quantitatively determining the disease incidence and/or the rate of lesion growth in said one or more offspring plants, establishing a genetic linkage map that links the observed disease incidence and/or rate of lesion growth to the presence of chromosomal markers of said donor tomato plant in said one or more offspring plants, and assigning to a QTL the contiguous markers on said map that are linked to a reduced disease incidence and/or a reduced lesion growth rate.

  • Patent number: 7453024
    Abstract: The invention relates to the field of genetic engineering of flavor, fragrance and bio-control agent development. More specifically it relates to a process for production of natural flavors, fragrances or bio-control agents by the control of one or more genes implicated in that process. The invention provides an isolated or recombinant nucleic acid or functional fragment thereof encoding a proteinaceous molecule essentially capable of flavor, fragrance and/or bio-control agent synthesis when provided with a suitable substrate under appropriate reaction conditions. The invention further provides a nucleic acid or functional fragment thereof encoding a proteinaceous molecule essentially capable of synthesizing at least a monoterpene alcohol linalool when contacted with geranyl diphosphate (GPP) and/or at least a sesquiterpene alcohol nerolidol when contacted with farnesyl diphosphate (FPP) under appropriate reaction conditions.

  • Publication number: 20080189811
    Abstract: A method for producing cucumber plants which are resistant to cucumber closteroviruses. The method comprises the steps of providing a Cucumis sativus plant which contains alleles that confer resistance to the closteroviruses defined by two QTLs, crossing said C. sativus plant with C. sativus culture breeding material, collecting the seeds resulting from said cross, regenerating the seeds into plants, evaluating the plants for resistance to the closteroviruses, and identifying and selecting resistant plants. Further, a resistant cucumber plant produced by the method as well as fruit or seed produced by said plant.

  • Publication number: 20070234441
    Abstract: The present invention relates to a plant of the Capsicum genus, which plant exhibits resistance to Pepper mild mottle virus (PMMoV) pathotype 1.2.3 due to the presence of the L4 resistance allele in the genome of said plant, wherein the genetic information responsible for the SNFD phenotype is absent from or is repressed in the genome of said plant at least to such an extent that the SNFD phenotype is not expressed. The present invention further relates to a method of producing a plant of the Capsicum genus that exhibits resistance to PMMoV pathotype 1.2.3, comprising the steps of a) providing a recipient plant of the Capsicum genus that is susceptible to PMMoV pathotype 1.2.

  • Patent number: 7235719
    Abstract: A cultivated tomato plant having a genome including an introgression derived from a green-fruited tomato, the green-fruited tomato being characterized by fruits having a brix value above 5 brix units, the introgression including a portion of chromosome 9 of the green-fruited tomato, the portion extending telomerically to a point so as to exclude from the portion an allele of the green-fruited tomato being responsible for an undesired trait selected from the group consisting of higher percent green fruit yield and longer internodes characterizing the green-fruited tomato as is compared to the cultivated tomato plant, the introgression inherently increasing by at least 6% a brix value characterizing fruits of the cultivated tomato plant as is compared to a nearly isogenic tomato plant lacking the introgression.
