Abstract: The present invention provides a method of herbicide treatment of selected female and male parents in a hybrid seed production system. The system results in enhanced trait purity and efficiency in the hybrid seed production system.

Abstract: The invention provides for identification and use of certain chloroplast transit peptides for efficient processing and localization of dicamba monooxygenase (DMO) enzyme in transgenic plants. Methods for producing dicamba tolerant plants, methods for controlling weed growth, and methods for producing food, feed, and other products are also provided, as well as seed that confers tolerance to dicamba when it is applied pre- or post-emergence.

Abstract: This invention provides polynucleotide molecules and methods for regulating genes in plants, e.g., by providing RNA for systemic regulation of genes. Various aspects of the invention provide polynucleotide molecules and methods for regulating endogenous genes and transgenes in a plant cell and polynucleotide molecules.

Abstract: The invention provides methods for weed control with dicamba and related herbicides. It was found that pre-emergent applications of dicamba at or near planting could be made without significant crop damage or yield loss. The techniques can be combined with the herbicide glyphosate to improve the degree of weed control and permit control of herbicide tolerant weeds.

Abstract: The invention provides a modified variant of dicamba monooxygenase (DMO). The invention relates to the unexpected finding that cells expressing this DMO exhibit high levels of tolerance to the herbicide dicamba. Compositions comprising DMO-encoding nucleic acids and methods of use are provided.

Abstract: The invention provides methods for the selection of transgenic cells. The invention relates to the unexpected finding that cells expressing a gene conferring tolerance to auxin-like herbicides such as dicamba may be directly selected from non-transgenic cells using auxin-like herbicides as a selective agent. In this manner, plants exhibiting tolerance to auxin-like herbicides can be directly produced without the need for separate selectable markers.

Abstract: The compositions and methods disclosed herein provide novel DNA molecules that encode glyphosate resistant EPSPS proteins and plants containing these new proteins. The plants that express the new EPSPS proteins are themselves tolerant to the herbicidal effects of glyphosate.

Abstract: Improved methods for the identification of transgenic plants containing NPTII protein are disclosed. Application of organosilicone surfactant in combination with kanamycin and/or paromomycin facilitates the identification of plants containing NPTII protein.

Abstract: Esterase-encoding recombinant plant genes are utilized to achieve metabolic deactivation as a means to genetically engineer plant resistance to pyridine herbicides. The esterase/pyridine system provided is further useful as a selection system for the identification of transformed plant cells.

Abstract: A novel method is provided wherein plants are first treated with an exogenous chemical (e.g., glyphosate herbicide) and then sequentially treated with a liquid accession agent which provides improved biological (e.g., herbicidal) effectiveness such that plants are controlled with lower rates of the applied exogenous chemical (e.g., glyphosate herbicide). Sequential application has been demonstrated to reduce the antagonism to herbicidal effectiveness that can be exhibited when the accession agent is added to a herbicide in a tank mix or simple coformulation. Typical accession agents employed in the disclosed method include a class of surfactants known as superwetting agents, such as certain organosilicone-based and fluorocarbon-based surfactants.
