POTATOES TRANSFORMED WITH DEHYDROASCORBATE REDUCTASE GENE DERIVED FROM SESAME HAIRY ROOT

摘要

Provided is a method for preparing a transformed potato which includes the increased contents of vitamin C in a tuber and a leaf, and improve resistivity to external stress so that the transformed potato grows up well. A transformed potato is transformed to a dihydroascorbate reductase gene derived from a hairy root of sesame. The increased amount of dihydroascorbate reductase gene is expressed in a leaf of the potato when compared with a wild potato under promoter control of a gene for general expression. The promoter of the gene for general expression is a CaMV35S promoter. The increased amount of dihydroascorbate reductase gene is expressed in a tuber of the potato when compared with the wild potato under promoter control of a gene for tuber specific expression. The promoter of the gene for tuber specific expression is a promoter of a patatin gene.
