  • Publication number: 20100297769
    Abstract: The invention is generally related to methods of generating plants transformed with novel autonomous mini-chromosomes. Mini-chromosomes with novel compositions and structures are used to transform plants cells which are in turn used to generate the plant. Methods for generating the plant include methods for delivering the mini-chromosome into plant cell to transform the cell, methods for selecting the transformed cell, and methods for isolating plants transformed with the mini-chromosome. Plants generated in the present invention contain novel genes introduced into their genome by integration into existing chromosomes.

  • Publication number: 20070028320
    Abstract: The present invention provides for the identification and cloning of functional plant centromeres in Arabidopsis. This will permit construction of stably inherited plant artificial chromosomes (PLACs) which can serve as vectors for the construction of transgenic plant and animal cells. In addition, information on the structure and function of these regions will prove valuable in isolating additional centromeric and centromere related genetic elements and polypeptides from other species.

  • Patent number: 7132240
    Abstract: The invention provides efficient methods for the isolation of centromeres from potentially any organism. Using the methods of the invention, methylated centromere DNA may be isolated from potentially any centromere in an organism.

  • Patent number: 7109149
    Abstract: The invention provides methods for the alteration of fertility in plants through modulation of floral GABA levels. The techniques of the invention may find use in plant breeding techniques. Also provided by the invention are assays for the screening of candidate modulators of GABA metabolism or GABA analogs through the identification of affects on fertility following application of the candidate modulator to a plant. The technique provides an alternative to animal testing and is amenable to large scale application.
