  • Patent number: 7825234
    Abstract: The present invention provides a method of screening for the purpose of obtaining gene expression modulating elements and gene insulator elements. The invention includes a method of identifying gene expression modulating elements and gene insulator elements through use of the following steps: a) locating intergenic regions of a plant genome that are flanked by a gene on each side that have differing gene expressions b) taking that intergenic region or a portion of that intergenic region and adding it to a cassette comprising an isolated gene c) introducing the cassette into a plant cell d) analyzing expression of the isolated gene. The present invention also includes identified sequences that act as gene expression modulating elements.
    Type: Grant
