This invention relates to the stilbene synthetic enzyme gene sequence of China staphylococcus wild oriental grape and its application, which uses mRNA differential display technique(mRNA differential display reverse transcriptional-PCR, DDRT-PCR) combining with the end Rapid amplification technique(Rapid amplification of cDNA ends, RACE) to clone the Vitas pseudoreticulata named stilbene synthetic enzyme of the China staphylococcus wild oriental grape, wherein the stilbene synthetic enzyme includes 7 components, the size of which are 1288bp,1343bp,1411bp,1468bp,1492bp,1506 b and 1556bp differently, and all of them code 392 amino acids. And the stilbene synthetic enzyme can transform 1 molecule coumarin acylated coenzyme A (P-Coumaroyl-CoA) and 3 molecule malonamide coenzyme A (Malonyl-CoA) into the Resveratrol. As a kind of Phytoalexins, Resveratrol can not only resist disease, but also can resist oxidation, prevent from cardiovascular disease and cancer, and lower blood fat and so on. This invention makes the plants such as wheat, tomato, rice, corn, soybean and cole have the ability of synthesizing Resveratrol through transforming gene method, which improves the disease resistant of these plants, and improves their nutritious health protection function.
