Patents by Inventor Angelo Spena

Angelo Spena has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method to control gene expression in bacteria, namely Rhizobiaceae, to improve root nodule development, nitrogen fixation and plant biomass production
    Publication number: 20040229365
    Abstract: A promintron sequence derived from an intervening sequence of the rolA gene of Agrobacterium rhizogenes strain A4 is described. The sequence is able to drive gene expression within bacteroids in all stages of nodule development in order to obtain, over the developmental time of the nodule, a constitutive expression of the gene(s) of interest. Uses of said sequence, derived vectors and recombinant bacteria are also described.

  • Methods for producing parthenocarpic or female sterile transgenic plants and methods for enhancing fruit setting and development
    Patent number: 6483012
    Abstract: Described is the use of the promoter region of the DefH9 gene of Anthirrhinum majus or of a promoter of a homologous gene displaying the same expression pattern and characteristics for the establishment of parthenocarpy or female sterility in plants, for increasing gynogenesis or for enhancing fruit setting and development. Also described are recombinant DNA molecules comprising a DefH9 promoter in combination with a DNA sequence which upon expression in plants leads to the above mentioned effects. Furthermore, described are plant cells and plants transformed with such recombinant DNA molecules.
