Ascorbic acid affects short-term response of Scenedesmus quadricauda to cadmium excess

Impact of ascorbate biosynthetic inhibitor (lycorine, LYC) on short-term cadmium (Cd) action (1 h, 100 μM) was studied in the green alga Scenedesmus quadricauda with 1 h or 24 h of LYC co-application. LYC suppressed Cd-induced increase in ascorbic acid and enhanced oxidative symptoms (ROS fluorescence) by modulating activities of antioxidative enzymes after 24 h of addition (decrease in superoxide dismutase, catalase and ascorbate peroxidase...
