Abstract
A method for enhancing the expression of a tomato phytoene synthese gene in a plant while avoiding or reducing co-suppression involves the synthesis of a DNA which is altered in nucleotide sequence (SEQ ID NO:1) and is capable of expression of a protein, ideally identical to that of a protein already expressed by a DNA already present in the plant. This method ensures that sequence similarity between the two genes is reduced enough to eliminate the phenomenon of co-suppression, allowing the over-expression of a specific phytoene synthese protein.
