文摘
A novel stilbene synthase gene (STS), cloned from Chinese wild Vitis pseudoreticulata (W. T. Wang) and responsible for synthesis of the phytoalexin resveratrol in grapevine, was successfully transferred into V. vinifera L. cv. Thompson Seedless via Agrobacterium tumefaciens-mediated transformation. Using transformation procedures developed in the present study, 72% GFP-positive germinated embryos were produced with about 38% of transformed embryos regenerated into normal plantlets. Integration of the STS gene into the transgenic plants was verified by PCR and Southern blot analysis. Expression of the STS gene was detected by high performance liquid chromatography (HPLC), which showed that the resveratrol concentration in the transgenic plants was 5.5 times higher than that in non-transformed control plants.
