  • Patent number: 7205459
    Abstract: According to the invention, there is provided an inbred corn plant designated LIZL5. This invention thus relates to the plants, seeds and tissue cultures of the inbred corn plant LIZL5, and to methods for producing a corn plant produced by crossing the inbred corn plant LIZL5 with itself or with another corn plant, such as another inbred. This invention further relates to corn seeds and plants produced by crossing the inbred plant LIZL5 with another corn plant, such as another inbred, and to crosses with related species. This invention further relates to the inbred and hybrid genetic complements of the inbred corn plant LIZL5, and also to the SSR and genetic isozyme typing profiles of inbred corn plant LIZL5. This invention further relates to methods of transforming the inbred LIZL5 and cells thereof, transformed plants produced by these methods, progeny transgenic plants, and seed derived therefrom.

  • Patent number: 5736369
    Abstract: To obtain a transgenic cereal plant which is stably transformed, an exposed cereal meristem is subjected to biolistic bombardment in order to target non-differentiated meristem cells for transformation. Immature embryos at the early proembryo, mid proembryo, late proembryo, transitional or early coleoptilar stage are harvested for biolistic bombardment. The meristem tissue or cells fated to contribute to the meristem then are manipulated in order to enlarge transgenic sectors, either through selection and/or through effecting a proliferation from the tissue of shoots or multiple meristems per se. The shoot population thus obtained then is screened, by means of a nonlethal enrichment assay, to identify either chimeric sectors that will contribute to germline transmission, or non-sectored, L2 periclinal chimeras that will by definition transmit to progeny.

  • Patent number: 5717129
    Abstract: A method of maintaining sterility in plants is disclosed. The method comprises genetic transformation of parental plant lines with a sterility gene that is genetically linked to a resistance gene which confers resistance to a selective agent, increasing the transgenic parental line and coating the seed of the increased transgenic parental line with a composition comprising the selective agent to which the resistance gene confers resistance. The resistance gene can be under the control of an inducible gene, or, alternatively, under the control of constitutive or tissue specific, including seed-specific, promoters.
