Phytochelatin synthesis and response of antioxidants during cadmium stress in Bacopa monnieri L.
The phytotoxicity imposed by cadmium (Cd) and its detoxifying responses of Bacopa monnieri L. have been investigated. Effect on biomass, photosynthetic pigments and protein level were evaluated asExpand

Lead detoxification by coontail (Ceratophyllum demersum L.) involves induction of phytochelatins and antioxidant system in response to its accumulation.
Coontail (Ceratophyllum demersum L.) plants when exposed to various concentrations of Pb (1-100microM) for 1-7days, exhibited both phytotoxic and tolerance responses. The specific responses wereExpand

Copper-induced oxidative stress and responses of antioxidants and phytochelatins in Hydrilla verticillata (L.f.) Royle.
Copper, though essential, is potentially toxic heavy metal at supraoptimal level and has widespread contamination. The present investigation was carried out to study the responses induced by lower asExpand

Phytochelatins and antioxidant systems respond differentially during arsenite and arsenate stress in Hydrilla verticillata (L.f.) Royle.
Serious contamination of aquatic systems by arsenic (As) in different parts of the world calls for the development of an in situ cost-effective phytoremediation technology. In the presentExpand

Lead bioaccumulation potential of an aquatic macrophyte Najas indica are related to antioxidant system.
Plants of Najas indica bioaccumulated significantly higher amounts of Pb (3554 microg g(-1) dw) when, exposed to varying concentrations of Pb(NO(3))(2).This also led to increased malondialdehydeExpand

Recent advances in arsenic accumulation and metabolism in rice
Arsenic is commonly present in subsoil and is a carcinogen in humans. Rice takes up arsenic and it accumulates in different plant parts, including grains, at levels several-fold higher than the soil.Expand
