Alejandro Araya 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).

  • Transgenic plants including a transgene consisting of a hybrid nucleic acid sequence, comprising at least one unedited mitochondrial gene fragment from higher plants and process for producing them
    Patent number: 6479735
    Abstract: Hybrid nucleic acid sequences including at least the coding region of an unedited mitochondrial gene of superior plants and controlling the male fertility of plants containing said sequences, transgenic plants having such sequences and methods of production of transgenic male-sterile plants and method of restoring male-fertile plants. The nuclei of the transgenic plants contain a hybrid sequence capable of being expressed (transgene), comprising at least one coding region of an unedited mitochondrial gene of superior plants and a sequence capable of transferring the protein expressed by said coding region, to the mitochondrion, said hybrid sequence being capable of modifying the male fertility of plants having incorporated said transgene, while leaving the other phenotype characteristics of said plants unaltered.
    Type: Grant
    Filed: January 4, 1999
    Date of Patent: November 12, 2002
    Assignee: Centre National de la Recherche Scientifique - CNRS
    Inventors: Alejandro Araya, Armand Mouras
