“…The induction of chlorophyll at low concentration of Hg in wheat plants is already reported (Liu et al 2010). The stimulating effects of low concentrations of heavy metal on several plant growth parameters is normally related to the hormetic effect, which probably represents an overcompensation response to a disruption in the homeostasis of the organism (Aina et al 2007). Skrebsky et al (2008) reported that there was an increase in both root and shoot biomass of Pfaffia glomerata plantlets at low Cd levels.…”

The phytotoxicity and oxidative damage in response to different concentrations of Hg (0.0, 2.5, 5.0, 10 and 25 μM) were evaluated in wheat plants. The root and shoot growth, content of chlorophyll and total soluble protein declined at 10 and 25 μM Hg. Roots of the plant were more affected as compared to the shoot. The malondialdehyde (MDA) quantity enhanced in the roots of wheat plants treated with 10 and 25 μM Hg and in the leaves of plants treated with 25 μM Hg. The concentration of H 2 O 2 decreased at low concentration and increased at high concentration of Hg. The induction of enzymatic antioxidants (catalase, CAT; ascorbate peroxidase, APX; peroxidase, POX and superoxide dismutase, SOD) was found in the roots and leaves of plants with increased concentration of Hg up to 10 μM and low activities of these enzymes were observed at 25 μM Hg. Also, the level of K, Ca and Mg declined in leaf tissues of Hg treated plants. Thus wheat plants exposed to lower concentrations of Hg did not experience any oxidative stress. However, on treatment with 10 μM Hg, the roots and leaves responded differently. Both the leaves and roots of plants treated with higher concentration of Hg were subjected to comparatively greater oxidative damage and demonstrated that the antioxidative components were not able to remove the stress due to higher concentration of Hg and thus might affect the productivity in wheat plants.

“…13 Different detoxifying mechanisms have been described to maintain cellular metal homeostasis, 5,[20][21][22] and some of them have been reported for rice. [23][24][25][26][27][28] In this context, it is interesting to note that the effect of 0.5 mM Ni on rice root PM-H + /ATPase is similar when applied in vitro as in vivo, while the strong inhibitory effect of 0.1-0.5 mM Cd measured in vitro is not longer present in plants treated with the metal for 5-10 days. 19 Thus, under our experimental conditions, a detoxifying mechanism seems to be induced in rice root cells soon after Cd uptake, reverting the immediate negative effects caused by this metal.…”

“…In another study, rice (Oryza sativa L.) seedlings were exposed to Cd concentrations. To assess the effects of Cd on plants; growth parameters, levels of gluthatione and phytochelatins were measured and Amplified Fragment Length Polymorphism (AFLP) technique was used to determine the Cd induced genetic variation (Aina et al, 2007).…”
