Abstract

Stress response of Dionaea muscipula J. Ellis to various light quality and quantity regimes, in the context of secondary metabolites production was determined. Venus Flytrap plants were cultivated in vitro in four different light regimes: fluorescence (50 μmol × m−2 × s−1 PPFD—control), fluorescence (120 μmol × m−2 × s−1 PPFD) and white LED (120 μmol × m−2 × s−1 PPFD) and in the darkness. Higher light intensity caused significant increase of membrane lipid peroxidation during the first 4 weeks of experiment. Whereas, light spectrum caused activation of defensive mechanisms. In the case of white LED, this mechanism was associated with the increased catalase activity and elevated synthesis of cinnamic acid derivatives, total phenols and plumbagin. While, in higher light intensity of fluorescence lamp, a reduction of chlorophyll content, and an increase amount of phenylopropanoids and plumbagin was observed. In turn, Venus Flytrap plants showed the highest activity of antioxidant enzymes, especially peroxidase, in the darkness. Higher concentration of plumbagin observed for the first time in response to different light quality and quantity, suggests that plumbagin is involved in photoprotection and/or in the antioxidant activity in Venus Flytrap tissue. Consequently, light might be used as an inorganic elicitator of 1,4-naphthoquinone derivatives and other phenolic compounds.
