Abstract
Antioxidative and microscopic responses in non-vascular (moss Taxiphyllum barbieri) and vascular (Ceratophyllum demersum) aquatic plants exposed to short-term (24 h) cadmium (Cd) excess (10 and 100 mu M) were compared. Ceratophyllum considerably accumulated Cd but less pronounced symptoms of oxidative stress were detected by confocal microscopy (at the level of general ROS, hydrogen peroxide, hydroxyl radical/peroxynitrite and superoxide) that could be related to enhanced activities of anti oxidative enzymes (SOD, CAT, APX). Amounts of ascorbic acid and non-protein thiols were higher in Ceratophyllum than in Taxiphyllum and increased with increasing Cd dose, which may help to better regulate circulation of free metal ions in Ceratophyllum mainly. Besides, it was observed that citric acid increased in Ceratophyllum while malic acid in Taxiphyllum in response to Cd which may also contribute to Cd chelation. Our data indicate that Ceratophyllum is a suitable species for Cd bioaccumulation while Taxiphyllum is more sensitive to Cd excess and thus suitable as indicator species. It was also proven that sensitive microscopic techniques allow the visualization of Cd-induced changes in aquatic plants even after short-term exposure when no morphological signs of damage are visible.
