Patent number: 10772326Abstract: 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.Type: GrantFiled: September 21, 2016Date of Patent: September 15, 2020Assignees: INTEGRATED PLANT GENETICS, INC., UNIVERSITY OF FLORIDA RESEARCH FOUNDATION, INC.Inventors: Dean W.

Patent number: 9392758Abstract: 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.Type: GrantFiled: August 24, 2012Date of Patent: July 19, 2016Assignee: INTEGRATED PLANT GENETICS, INC.Inventors: Dean W. Gabriel, Giovana J. Perazzo-Ratto, Yingnan Jiang
