Abstract
The present invention relates to the use of recombinant DNA technology in the modification of plant oils. In particular, the invention relates to the identification of novel promoter sequences of the FAE1-1 and FAE1-2 genes of Brassica napus and the FAE1 gene of Arabidopsis thaliana. The invention also relates to the host cells and plants transformed with the nucleic acid sequences of the invention, and methods of producing oil.
Claims15
A recombinant or isolated nucleic acid molecule comprising or consisting of a promoter which is
- (i) the FAE1-1 promoter sequence as shown in FIG. 1 or 3;
- (ii) the FAE1-2 promoter sequence as shown in FIG. 2 or 4;
- (iii) the FAE1-1 promoter sequence shown in FIG. 5;
- (iv) a promoter sequence which naturally regulates expression of a coding sequence which is substantially identical to the sequences of FIG. 8 or 9;
- (v) a sequence which hybridises under stringent conditions to the complement of any one of (i) to (iv).
A recombinant or isolated nucleic acid molecule comprising or consisting of one or more regulatory elements derived from any one of the sequences (i) to (iv) which is both seed specific and temporally specific for the oil biosynthesis pathway.
