Abstract
A method of increasing the content of one or more transgene-coded proteins or peptides in a plant is described. The increase is an effect of a decrease in the concentration of an ATP/ADP transporter in the plant. The method depends on transformation with and expression of a cDNA encoding an ATP/ADP transporter operably linked in antisense orientation to a promoter active in the plant.
Claims7
A method of increasing the content of one or more transgene-coded proteins or peptides in a transgenic potato plant comprising inhibiting a potato plastidary ATP/ADP transporter gene in said plant by antisense inhibition thereof, wherein the potato plant is transformed with and expresses (i) an antisense gene construct for the plastidiary ATP/ADP transporter gene, (ii) a selectable marker gene and (iii) one or more further desired transgenes, wherein the content of the transgene-coded protein or peptide in said transgenic potato plant is increased relative to the content of the transgene-coded protein or peptide in a control plant of the same genetic background.
