Alleviation of Metal-Induced Toxicity in Aquatic Plants by Exogenous Compounds: a Mini-Review
2016
Oukarroum, Abdallah
Metals are significant environmental pollutants, and their toxicity is a problem for all living organisms. Indeed, aquatic plants are particularly sensitive to the excess of metal ions. Several researches report that aquatic plants exposed to metal-induced toxicity showed similar responses (e.g. inhibition of growth and induction of oxidative stress). Meanwhile, many studies were involved to counter these toxicities. This paper provides a brief review of the role of the exogenous supply of some compounds in the alleviation or reduction of toxicity in aquatic plants generated by metals. Particular attention is given to the role of polyamine, proline, nitric oxide, glutathione and phytochelatin.
