“…Until recently, only a few reports about the interactive effects of As and Se on plant uptake and accumulation were available and most of them are focused on terrestrial plants, such as Chinese brake fern (Pteris vittata L.; Feng et al 2009;Srivastava et al 2009), mung bean (Phaseolus aureus Roxb. ; Malik et al 2012), barley (Hordeum vulgare ; Ebbs and Weinstein 2001), and alfalfa (Khattak et al 1991).…”

In addition, most of the present studies were focused on interaction of single inorganic As or Se species, such as As(V) and Se(IV) (Feng et al 2009), As(V) and Se(VI) (Srivastava et al 2009;Ebbs and Weinstein 2001). There is a lack of systematic information on the interaction between two inorganic As species and two inorganic Se species in higher plant such as rice grown under anaerobic condition.…”

There is a lack of information on the interactive relationship of absorption and transformation between two inorganic arsenic (As) species and two inorganic selenium (Se) species in rice grown under hydroponic condition. Interactive effects of inorganic As (As(III)) and (As(V)) and Se (Se(IV)and Se(VI)) species on their uptake, accumulation, and translocation in rice (Oryza sativa L.) seedlings were investigated in hydroponic culture. The results clearly showed the interactive effects of inorganic As and Se on their uptake by rice. The presence of Se reduced the sum of As species in the rice shoots regardless of Se speciation. If Se is present as Se(IV), then is it is accompanied by a corresponding increase of the sum of As species, but if Se is present as Se(VI), then there is no change in the sum of As species in rice roots. These effects are observed regardless of initial As speciation. When the rice plants are exposed to Se(IV), the presence of As increases the sum of Se species in the roots, and decreases the sum of Se species in the corresponding shoots. This effect is more pronounced for As(III) than for As(V). There is no effect on Se during exposure to Se(VI). Co-existence of As also increased SeMet in rice roots.

“…Numerous studies have been conducted to investigate As uptake and transport in plants under hydroponic conditions, wherein, plants are cultivated with no soil to support root systems [18,19]. The use of hydroponics, compared to conventional cultivation methods, allows for better characterization of contaminant uptake, because potential interactions between the soil matrix and elements of interest are minimized [20,21].…”

“…In recent years, major scientific advances have been taking in understanding the plant molecular-genetic mechanisms that drive metal hyperaccumulation in plants. Pteris vittata L. was the first known fern which demonstrated significant As hyperaccumulator activity during the removal of As from contaminated water [5,18]. Numerous other studies have identified a variety of plants including floating macrophytes like water hyacinth, duckweed, butterfly fern, and water fern [22], Hydrilla verticillata (L.f.) Royle [23] and P. vittata [24] to remediate deleterious As contamination from ground waters.…”

Ten Indian mustard (Brassica juncea L.) genotypes were screened for their phytoremediation potential for arsenic (As) contaminated water under laboratory-controlled conditions. The genotypes were grown in a hydroponic chamber for 20 days in 250-mL beakers containing As-contaminated water. During plant development, changes in plant growth, biomass, and total As were evaluated. Of the 10 genotypes (Pusa Agrani, BTO, Pusa Kranti, Pusa Bahar, Pusa Bold, Pusa Basant, Pusa Jai Kisan, Arka Vardhan, Varuna, and Vaibhav) Pusa Jai Kisan was the most effective in phytoremediating Ascontaminated water under hydroponic conditions. This will provide new information for Indian mustard genotypes for phytoremediating As-contaminated soils.

“…The formation of Se-aminoacids, in turn, is supposed to enhance ethylene production [13], which can cause damages to plant growth. Some biochemical and physiological studies were conducted with Se-compounds in plant systems [8,14,15], but no physiological co-action between Se and Al has been stablished. In this work the effects of Se at low concentration added to the growth medium as a protector against Al toxicity were investigated.…”

A dual role of selenium in the growth control of seedlings of Stylosanthes humilis

The growth of seedlings of Townsville sytlo (Stylosanthes humilis H.B.K.) is inhibited by aluminium (Al) ions, their elongation being recovered with sodium selenate at 1.0 µM. Methyl viologen and hydrogen peroxide, reactive oxygen species (ROS)-generating compounds, also inhibited seedling elongation and again growth was relieved by selenate. Selenate, thus, seemed to be operating as a ROS quencher, since N-acetylcysteine (NAC), an antioxidant compound, also stimulated largely the growth of Al-inhibited seedlings. At a higher concentration (0.1 mM), however, selenate inhibited seedling growth and elongation was recovered by NAC. Ethylene production by selenate plus NAC-treated seedlings was very higher and thus the gaseous hormone was not responsible for the seedling growth inhibition caused by selenate. Hence, it seems that at high levels selenate operates as a ROS-generating compound whose effects were counteracted by NAC. It can be deduced that, at low concentration, selenate behaves as a ROS quencher and at high level as a ROS-promoting species.
