The invention relates to plants or products derivable therefrom having an elevated content of Vitamin C, by methods of genetic modification. In particular the invention relates to a process for producing plants or plant tissues having an elevated content of vitamin C, comprising the steps, (i) transformation of a plant cell with a gene construct followed by (ii) the regeneration of a genetically modified plant or plant tissue from the transformed plant cell of the transformation step (i), wherein the gene construct comprises a polynucleotide sequence capable of expressing a polypeptide product with an ability to catalyse conversion of L-galactonono-1,4-lactone to vitamin C, characterised in that said polynucleotide sequence is derived from a non-plant source. |
