Abstract

Effects of Exogenous Spermidine on Cell Wall Composition and Carbohydrate Metabolism of Marsilea Plants under Cadmium Stress

In an experiment to detect the cellular changes of carbohydrate content and its related enzymatic activities, a study was undertaken with Marsilea minuta L., an aquatic fern species in simulated condition of cadmium (Cd) toxicity. From the varying doses of Cd (0, 50, 100 and 200 μM) and supplemented with spermidine (2 mM), it revealed that plants were suffered from accumulation of total carbohydrate in a dose-dependent manner under Cd stress. Maximum depletion of carbohydrate content was 58% with respect to control which was retrieved by 1.42 fold with spermidine application. In a similar manner, plants were also affected with starch, total reducing sugar content by 42% and 63.04% respectively over the control. The fall in both starch and total reducing sugar were retrieved by plants by 1.32 fold and 1.52 fold, respectively.
