  • Patent number: 10772326
    Abstract: Methods and compositions based upon natural phenolic aromatic aldehydes (ex: cinnamaldehyde, benzaldehyde) are provided, which find use as curing agents for systemic bacterial infections of living plants, in particular against Gram negative bacteria and more particularly species of Liberibacter, including Ca. Liberibacter asiaticus. The curing agent compositions described are used synergistically with other antimicrobial compounds, such as those that plants manufacture or release as a result of biotic or abiotic stresses, including the application of the subject aldehydes, certain proteins, whether produced by recombinant methods or not, nanoparticles, nanoemulsions, or by natural essential oils such as carvacrol or allicin. The aromatic aldehydes have high volatility and exhibit phytotoxicity when applied above certain amounts. Systemic infections and infestations of a variety of plant parts can be treated, including those of leaves and roots.

  • Patent number: 9392758
    Abstract: The invention relates to methods and compositions for genetic transformation of both juvenile and mature citrus. In some embodiments, the invention provides methods and compositions for genetic transformation of citrus using Rhizobia-mediated DNA delivery, and also methods of enhancing the frequency of genetic transformation of mature citrus by any DNA transfer method, including Sinorhizobium. Internodal stem sections prepared from epicotyls of citrus seedlings or freshly emerging shoots of mature citrus plants (e.g., first shoots from buds of mature plants following grafting onto rootstock or very young shoots of mature plants) are preconditioned for transformation by inducing callus formation on an artificial medium. All callus and any developing meristematic regions in immediately adjacent tissue are substantially or completely removed and the preconditioned explants are then transformed by Sinorhizobium or other known methods.

  • Patent number: 4818693
    Abstract: Methods and compositions are provided to improve the quantity of embryos obtained by induction of somatic plant tissue. These involve the addition of effective amounts of selected amino acids, their derivatives or combinations of these as a source of reduced nitrogen, together with an optimum auxin dosage to the nutritive media used to regenerate or maintain the embryonic tissue. A synergistic effect is found by adding these amino acids either in combination or in combination with ammonium ion together with the selected auxin dosage.

  • Patent number: 4777762
    Abstract: Methods and materials are provided for desiccated analogs of botanic seeds which are created by removing a portion of the water by slow or fast drying so that the plant tissue is no longer saturated with water. In a second embodiment, the meristematic tissue is encapsulated in a gel or polymer followed by dehydration. In another embodiment, the meristematic tissue is dehydrated prior to encapsulation in a gel. Protectants can be incorporated in the gel capsule. Meristematic tissue can be isolated from, for example, somatic embryos, zygotic and germ line sources.
