  • Patent number: 6696294
    Abstract: The present invention provides methods for generating and identifying mutations in any target gene of a polyploid plant species. In a preferred aspect of the present invention, a plant is constructed and/or selected that has at least one copy of a functional, target gene located exclusively in only one of its homoeologous, or homologous, genomes. Seed derived from the selected plant are then contacted with an effective amount of at least one mutagenic agent, the treated seed are germinated and the seeds or plants derived therefrom, are screened for mutations in the target gene. Thus, the inventive concepts set forth herein can be used to create, select and identify mutations in any target gene of any suitable polyploid plant, thereby providing a source of numerous, readily-identifiable mutations that can, if so desired, be used in crosses to develop unique new crop cultivars.

  • Patent number: 6639132
    Abstract: Improved corn lines having high protein and/or oil content and a method for producing such a lines. In another embodiment, improved corn lines having high oleic fatty-acid content, and/or either elevated or lowered saturated fat content, and a method for producing such a lines. In yet another embodiment, improved corn lines having a starch composition including starch components having a lower peak onset, having lower or higher enthalpy of gelatinization (cal/g), having lower or higher range of gelatinization (° C.), and/or having lower or higher percentage retrogradation. According to the present invention, new genes are introduced from a novel source, viz. Tripsacum dactyloides L., into the Corn-Belt genome or other conventional corn lines and thus the genetic diversity is increased and germplasm and value-added trait enhancement are allowed through traditional plant breeding practices. Introgression merges Tripsacum genetic material into the corn breeding stock.

  • Publication number: 20030024015
    Abstract: A process is provided for selecting cotton plants which exhibit naturally-occurring genetically-controlled herbicide resistance. Initially cotton seeds are subjected to cold stress (as described) and cotton plants are formed from the seeds that germinate. Seeds are formed following the self-pollination of the resulting plants. These seeds upon maturity are soaked in a liquid containing a herbicide (e.g., a glyphosate) for a period of time sufficient for the herbicide to reach the embryos of the seeds. The seeds following such soaking are planted in a growing medium and produce at least one cotton plant that displays herbicide resistance. The plant is analyzed for the possible presence of a foreign gene for herbicide resistance that would attribute the manifest herbicide resistance to genetic engineering. A cotton plant is selected wherein the herbicide resistance is not attributable to genetic engineering.

  • Publication number: 20020004939
    Abstract: Morphological markers are used in a method of visually identifying plants transformed with a nucleotide sequence (e.g., a heterologous gene). The nucleotide sequence is transformed into a plant that exhibits an abnormal phenotype for a morphological marker. If the transformation of the plant is successful, the progeny of the transformed plant will exhibit a normal phenotype. In a preferred embodiment, the plant is Arabidopsis and the morphological marker is Gl1, which is associated with trichome production on plant leaves. The method is also useful for identifying plants that are homozygous for the transformed gene, and for identifying transformants in the T2 generation that are true crosses, rather than self-crosses.

    Abstract: Insertions into a gene of known sequence can be generated by crossing two parent plants, one of which contains a transposable element, to produce F.sub.1 progeny plants in which the insertion is detected by means of a PCR. F.sub.1 progeny plants containing such an insertion are self-fertilized to produce F.sub.2 progeny which are homozygous for the insertion. The function of a gene disabled by the insertion can be ascertained from a comparison of the phenotype of the F.sub.2 progeny with a parental phenotype. Large numbers of F.sub.1 progeny can be tested simultaneously for the presence of insertions. A collection of F.sub.2 seed can be stored and used for phenotype comparison when an insertion is detected.
