Patent number: 6696294Abstract: 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.Type: GrantFiled: December 18, 2000Date of Patent: February 24, 2004Assignee: Northwest Plant Breeding Co.Inventor: Calvin F.

Publication number: 20030024015Abstract: 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.Type: ApplicationFiled: February 14, 2001Publication date: January 30, 2003Inventor: William H.

Publication number: 20020004939Abstract: 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.Type: ApplicationFiled: April 11, 2001Publication date: January 10, 2002Inventors: Douglas C.
