“…Notwithstanding the publications previously mentioned, it is manifest a scarcity of information on the macroalgae action protecting genome integrity of fish. As a Proof of Concept towards a genoprotective potential of marine macroalgae in fish, it was demonstrated that a Kappaphycus alvarezii (red algae) extract exhibits potent anti-genotoxicity effects in Jarbua fish (Terapon jarbua) against DNA damage induced by mercury (Hg) (Nagarani et al, 2012). Moreover, Zinadah et al (2013) showed that, when flathead grey mullet (Mugil cephalus) diet was supplemented with 10-20 % of Ulva lactuca or Caulerpa prolifera (green algae), a considerable DNA protection was achieved.…”

“…On the contrary, Cd is a non-essential heavy metal ion that causes disturbances in plant growth, photosynthesis, ion and water transport, as well as decreases in plant enzyme activities through reactions between the Cd 2+ and thiol groups. When reaching a certain concentration in plant tissue, both metallic trace elements are involved in the generation of reactive oxygen species (ROS), which react with lipids, proteins, photosynthetic pigments, and nucleic acids, causing lipid peroxidation, membrane damage, metabolite degradation, inactivation of enzymes, and even cell death (Nagarani et al, 2012). The increase of lipid peroxidation products such as malondialdehyde (MDA) as a consequence of the oxidative stress has been considered as an indicator of free radical production and tissue damage.…”

The objective of the present work was to evaluate the extent of Cd-and Cu-induced oxidative stress and the antioxidant response triggered in the halophyte species Atriplex halimus after metallic trace elements exposure. Plants were treated for one month with Cd 2+ or Cu 2+ (400 µM) in the absence or presence of 200 mM NaCl in the irrigation solution. The interaction between salinity and heavy metal stress was analyzed in relation to plant growth, tissue ion contents (Na + , K + and Mg 2+ ), oxidative damage and antioxidative metabolism. Data indicate that shoot and root weight significantly decreased as a consequence of Cd 2+ -or Cu 2+ -induced stress. Metallic stress leads to unbalanced nutrient uptake by reducing the translocation of K + and Mg 2+ from the root to the shoot. The levels of malondialdehyde increased in root tissue when Cd, and especially Cu, were added to the irrigation solution, indicating that oxidative damage occurred. Results showed that NaCl gave a partial protection against Cd and Cu induced toxicity, although these contaminants had distinct influence on plant physiology. It can be concluded that salinity drastically modified heavy metal absorption and improved plant growth. Salinity also decreased oxidative damage, but differently in plants exposed to Cd or Cu stress.Additional key words: Atriplex halimus; oxidative damage; trace element toxicity; salinity Abbreviations used: APX (ascorbate peroxidase); CAT (catalase); DTNB (dinitrobenzoic acid); FW (fresh weight); GPX (guaiacol peroxidase); GSH (reduced glutathione); GSSG (oxidised glutathione); MDA (malondialdehyde); PC (phytochelatin); ROS (reactive oxygen species); SOD (superoxide dismutase); tGSH (total GSH) Authors' contributions: Cation determination assays: IB.
