  • Chimeric plant genes based on upstream regulatory elements of helianthinin
    Patent number: 5905186
    Abstract: Helianthinin is an 11S seed storage protein of sunflower embryos. The present invention is directed to the 5' regulatory regions of helianthinin genes. More particularly, the present invention is directed to specific cis-regulatory elements of this regulatory region which direct tissue-specific gene expression. The present invention provides chimeric genes comprising the cis-regulatory elements linked to a coding sequence from a heterologous gene to control expression of these genes.

  • Chimeric plant genes based on upstream regulatory elements of helianthinin
    Patent number: 5859325
    Abstract: Helianthinin is an 11S seed storage protein of sunflower embryos. The present invention is directed to the 5' regulatory regions of helianthinin genes. More particularly, the present invention is directed to specific cis-regulatory elements of this regulatory region which direct tissue-specific, temporally-regulated, or abscisic acid-responsive gene expression. The present invention provides chimeric genes comprising the cis-regulatory elements linked to a coding sequence from a heterologous gene to control expression of these genes. The chimeric genes provided by the instant invention are useful in conferring herbicide resistance and improved seed lipid quality to transgenic plants.

  • Chimeric gene for the transformation of plants
    Patent number: 5792930
    Abstract: The present invention relates to a chimeric gene for conferring to plants an increased tolerance to a herbicide. This chimeric gene comprises, in the direction of transcription, a promoter region, a transit peptide region, a sequence encoding glyphosate tolerance and a polyadenylation signal region, wherein the promoter region consists of at least one promoter of a plant histone gene enabling the expression of the herbicide tolerance protein in the regions of glyphosate accumulation. The present invention further provides vectors containing the present chimeric genes, of glyphosate-tolerant plants.
