Title:
A METHOD FOR PRODUCING SEEDS HAVING ALTERED PROTEIN/FATTY ACID COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2001/034812
Kind Code:
A1
Abstract:
A method for altering the protein/fatty acid of seeds by introducing antisense gene, it comprises the following steps: (1) the cloning of genes of the phosphoenopyruvate carboxylase or acetyl-CoA carboxylase, or their fragments; (2) the construction of the corresponding antisense gene; (3) introducing antisense gene into the cell of oilseeds crop, so that the activity of the phosphoenopyruvate carboxylase or the acetyl-CoA carboxylase which is the key enzyme for protein synthesis will be changed, the flow direction of the biosynthetic co-substrate PEP could be ajusted, so that the protein/fatty acid composition of seeds will be altered. The application can be used for altering the protein/fatty acid composition of oilseeds crop.
