Abstract: This invention describes a simple method useful for the excision and isolation of maize immature embryos. The embryos are useful for plant tissue culture and transformation methods.
Abstract: Methods for the production of reversibly male-sterile plants by introduction of a polynucleotide encoding a GA-insensitive mutant protein are disclosed along with nucleic acid constructs and transformed cells useful in the production of such plants. Also disclosed are the use of plants containing recombinant nucleic acid sequences in preventing pollination of plants with pollen containing one or more transgenes and in the introduction of economically important traits into elite varieties of plants.
Abstract: The present invention provides a DNA construct composition that relates to transgenic glyphosate tolerant wheat plants. The invention relates to the wheat plant 33391, the progeny thereof and to methods for the detection of wheat plant 33391 and its progeny and compositions thereof using an insertion junction sequence designated SEQ ID NO: 6.

Abstract: The present invention relates to a rapid transformation and regeneration system for plants. In particular, the invention relates to a plant tissue preparation system. The transformation method is efficient and reliable for production of fertile plants with improved agronomic qualities.
Abstract: A method is disclosed for the Agrobacterium-mediated germline genetic transformation of soybean. The method is based on Agrobacterium-mediated gene delivery to individual cells in a freshly germinated soybean meristem, which cells can be induced directly to form shoots that give rise to transgenic plants. This method does not involve callus-phase tissue culture and is rapid and efficient.

Abstract: The present invention relates to improved methods for producing transgenic sunflower plants. Specifically, methods are disclosed for transforming sunflower tissues and regenerating fertile transgenic plants therefrom. The methods are particularly amenable to sunflower tissues, such as cotyledons, which have proven refractory to previous methods of transformation and regeneration.
Abstract: DNA constructs and other compositions and methods for controlling gene expression in eukaryotic cells and organisms are derived from bacterial quorum sensing systems. One or more cis elements from the luxI promoter (“lux box”) or a functionally similar sequence are incorporated in a eukaryotic promoter. A receptor protein from the LuxR family of transcriptional regulators, upon binding an acylated homoserine lactone (AHL) compound, interacts with the lux box, modulating the activity of the promoter.

Abstract: A method is provided for transforming Brassica plants to express DNA sequences of interest from the plant cell plastid. The method allows the transformation of Brassica plant tissue with heterologous DNA constructs. Such DNA constructs comprise, in the 5? to 3? direction of transcription, a promoter region functional in a plant plastid and a DNA sequence of interest. The invention further provides for Brassica cells in which the plastids contain heterologous DNA constructs.
Abstract: Novel compositions and methods useful for genetic engineering of plant cells are provided. In particular, plastid constructs comprising recombining sites are provided. Such constructs find use in methods for site specific recombination in plant cell plastids. Plant cells and plants comprising the constructs described herein, as well as plant cells and plants produced by the methods of the present invention are of interest.
