There is a growing interest in producing food plants with increased amounts of antioxidants because of their potential health benefits. Polyphenolic secondary metabolites, such as flavonoids and stilbenes, have been investigated for their significant antioxidant activity, important both for plant physiology and human nutrition. With the aim to verify whether the synthesis of resveratrol in tomato fruit affected the redox status of transformed tomato tissues, in the present work we took advantage of the availability of two different transgenic tomato lines in which a grape stilbene synthase gene was expressed under a constitutive or a tissue specific promoter, respectively. The induction of resveratrol synthesis in tomato affected the redox status of transformed tomato fruit. In particular, ascorbate and glutathione pool increased, significantly and proportionally to the amount of the .. View More»
