Estimating the term…
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.
An isolated nucleic acid capable of directing seed-specific gene expression consisting of nucleotides 2304 to 2401 of SEQ ID NO:1.
A chimeric plant gene comprising at least nucleotides 2304 to 2401 of SEQ ID NO:1 operably linked to the coding sequence of a heterologous gene wherein said coding sequence is operably linked to a 3' polyadenylation site, and wherein said nucleotides 2304 to 2401 direct seed specific expression of said coding region.
