摘要: The heavy metal Cadmium (Cd), added to the water bodies through weathering of rocks and human activities, constitutes one major environmental pollutants toxic plants. This study examines proteome changes in roots actively growing Kandelia candel (L.) Druce when challenged with Cd. mangrove-like species proliferates estuaries bays is a potential choice for phytoremediation A total 53 proteins were up- or down-regulated following short-term Cd treatment. identities differentially expressed determined by MALDI-TOF/TOF. Approximately half up-regulated are involved oxidative response, including antioxidant enzymes, enzymes required glutathione biosynthesis, TCA PPP cycles generating ATP, NADH NADPH. These results support prediction that prompt antioxidative response necessary reduction stress caused set stage further investigating candel.
