  • Patent number: 7002058
    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.

  • Patent number: 6998516
    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.

  • Patent number: 6943243
    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.

  • Patent number: 6891086
    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.
