In vitro resveratrol-rich callus tissues derived from Vitis thunbergii Sieb. et Zucc and method for producing the same
The present invention provides an in vitro resveratrol-rich callus tissue of Vitis thunbergii Sieb. et Zucc. which is a callus tissue developed from a tissue culture system containing one or more plant growth regulators (PGRs) and cultured from a stem or a petiole tissue explant of a wild type of V. thunbergii or a cultivated plantlet of V. thunbergii. The cultivated plantlet is in turn derived from a shoot of the wild type of V. thunbergii cultivated in a plantlet culture system containing no PGRs. The in vitro resveratrol-rich callus tissue of V. thunbergii is characterized by its containing at least about 1,000 to 10,000 mg/kg of dried weight of resveratrol, predominantly in the form of trans-resveratrol and/or resveratrol-O-glucoside, and being ready for harvest or subculture in about 30 days.
