“…The increase of Ca content in plant tissues was also observed by He et al (2004) and by Wu and Huang (1992) under selenate stress. Similarly, under arsenic stress, increasing Ca content was found in Spartina alterniflora (Carbonell et al 1998) and winter wheat (Triticum aestivum L.) (Liu et al 2008). Increases in Mg content in this study was in line with the results of He et al (2004) in the field experiment.…”

Selenium has been proven to be an antioxidant in plants at low dosages. To understand better the mechanisms of Se toxicity and benefit to plants, more investigations about effects of Se on the uptake of essential elements in plants would be desirable. In this study, hydroponic (nutrient solution culture) and pot (soil culture) experiments were simultaneously conducted to investigate the effects of Se on the uptake and distribution of essential elements in Pteris vittata. L (Chinese brake fern), an arsenic (As)-hyperaccumulator and a selenium (Se)-accumulator. Chinese brake fern took up much more Se in nutrient solution culture than in soil culture, with the highest Se content recorded as 1,573 mg kg −1 in the roots, demonstrating remarkable tolerance to Se. In soil culture, Chinese brake fern also accumulated high content of Se, with the highest content measured as 81 mg kg −1 and 233 mg kg

“…However, +As treatments did not exert any significant difference in root and shoot length and root weight, which was different to other studies (Marin et al, 1993;Abedin et al, 2002b). In other investigations, addition of arsenate had not revealed any significant reductions (Marin et al, 1993;Carbonell et al, 1998;, possibly due to different growing conditions and genotypes. In addition, root length was slightly enhanced by aerated treatments compared with stagnant treatments, which is in agreement with other studies (Comis, 1997;Wu et al, 2012).…”

Widespread contamination of rice with arsenic (As) has revealed a major exposure pathway to humans. The present study aimed to investigate the effects of oxygen in the rhizosphere on phosphate transporter (for arsenate transportation) expressions in four rice genotypes, on As and phosphate accumulation and As speciation.Oxygenation marginally increased root and shoot length. Total As concentrations in rice roots were dramatically reduced following oxygenation compared to stagnant treatments (p <0.001). Oxygenated treatments significantly increased arsenate whilst reducing arsenite concentrations in roots (p < 0.001). Root arsenite concentrations were 1.5-2.5 times greater in stagnant than in oxygenated treatments. Total P concentrations in rice roots were dramatically increased following aeration compared to stagnant treatments.

“…Results published by Carbonell et al and Marin et al are difficult to compare with ours since the culture conditions for plants were different in each case. [18][19][20] However, generally it can be said that all published data show, as do our results, that soluble inorganic As is better taken up by plants than methylated-As species independent of plant species and culture conditions. Tlustos et al found no difference in As uptake by radish plants grown in As III , As V or DMA V amended soil.…”

Environmental context. The molecular occurrence of arsenic in soils can vary as a result of soil conditions and/or application of arsenic-containing herbicides or fertiliser. Although large amounts of As-containing herbicides are used for different crops, there is still a lack of understanding as to how the molecular form of As determines the uptake of arsenic into plants and, in particular, the translocation into shoot and grain.Abstract. The uptake and translocation into shoots of arsenate, methylarsonate (MA), and dimethylarsinate (DMA) by 46 different plant species were studied. The plants (n = 3 per As species) were exposed for 24 h to 1 mg of As per litre under identical conditions. Total arsenic was measured in the roots and the shoots by acid digestion and inductively coupled plasma mass spectrometry from which, besides total As values, root absorption factors and shoot-to-root transfer factors were calculated. As uptake into the root for the different plant species ranged from 1.2 to 95 (µg of As per g of dry weight) for As V , from 0.9 to 44 for MA V and from 0.8 to 13 for DMA V , whereas in shoots the As concentration ranged from 0.10 to 17 for As V , 0.1 to 13 for MA V , and 0.2 to 17 for DMA V . The mean root absorption factor for As V (1.2 to 95%) was five times higher than for DMA V (0.8 to 13%) and 2.5 times higher than for MA V (0.9 to 44%). Although the uptake of arsenic in the form of As V was significantly higher than that of MA V and DMA V , the translocation of the methylated species was more efficient in most plant species studied. Thus, an exposure of plants to DMA V or MA V can result in higher arsenic concentrations in the shoots than when exposed to As V . Shoot-to-root transfer factors (TFs) for all plants varied with plant and arsenic species. While As V had a median TF of 0.09, the TF of DMA V was nearly a factor of 10 higher (0.81). The median TF for MA V was in between (0.30). Although the TF for MA V correlates well with the TF for DMA V , the plants can be separated into two groups according to their TF of DMA V in relation to their TF of As V . One group can immobilise DMA V in the roots, while the other group translocates DMA V very efficiently into the shoot. The reason for this is as yet unknown.
