“…Conductivity indices and pH of soil treated with inorganic Se (0, 7 and 140 µg kg -1 soil), organic Se (leaf and stem residue, 0 and 7 µg Se kg -1 soil) and autoclaved soil with inorganic Se (0 and 7 µg kg -1 soil) at the different growth stages decrease was especially marked for the SeMet treatment. A study by Jain et al (2015) found that the application of selenite reduced the chlorophyll content in sugarcane plants. The negative effect of Se on chlorophyll content may due to an inhibition of the pigment synthesis (Prasad and Prasad 1987).…”

The uptake by and subsequent translocation of selenium (Se) within the plant is dependent on its chemical from and soil properties that dictate this trace element’s bioavailability. Plant species differ in their tendency to accumulate Se. Se taken-up by plants is returned to soil in plant residues, but the bioavailability of organic Se in those residues is poorly known. We investigated the impact of inorganic (Na2SeO4), organic (Se-enriched stem and leaf residues) Se applications and also soil microbial respiration on the growth and Se concentrations of various plant organs of oilseed rape (Brassica napus L.) during its development from the rosette to the seed filling stage. Both inorganic and organic Se slightly improved plant growth and enhanced plant development. Inorganic Se was more bioavailable than the organic forms and resulted in 3-fold to 6-fold higher Se concentrations in the siliques. Inorganic Se in autoclaved soil tended to elevate the Se concentration in all plant parts and at all growth stages. The organic Se raised Se concentrations in plants much less effectively than the inorganic selenate. Therefore, the use of inorganic Se is still recommended for biofortification.

“…Metallothioneins (MTs) as low molecular weight metal binding proteins showed an increase in their expression along with increasing N-Se concentrations. Increasing the expression pattern of MTs was reported in sugarcane treated with graded concentration of Se (Jain et al, 2015). This result revealed that N-Se cause an induction of MTs expression.…”

Atrazine is a widely used herbicide on many crops and is considered one of water pollutant with approved biological hazards on plants, animals and human. Vicia faba seedlings as a biological system, is used to investigate the genotoxicity of Atrazine. Also, Nano selenium (N-Se), a Nano particle with reactive oxygen species scavenging activity was applied to reduce the genotoxicity of Atrazine. Atrazine treatment at concentration of 35 mg/L is applied. Two concentrations of N-Se (10 and 20 ppm) were used alone and in combination with Atrazine (35 mg/L) in addition to control treatment. Changes in germination percentage, shoot and root length, hydrogen peroxide (H 2 O 2) content, lipid peroxidation product malondialdehyde (MDA), chromosomal aberrations, and mitotic index were determined. Semi quantitative RT-PCR analysis (sqRT-PCR) was applied to investigate associated changes in expression pattern of some stress related genes such as antioxidant enzymes, heat shock proteins (HSP17.9, HSP70.1), photosystem II (PSII) and Metalothioniene (MT). Atrazine treatment recorded the lowest germination percentage and caused a reduction in shoot and root length. Significant increase in H 2 O 2 value, MDA contents, and chromosomal abnormalities percent resulted in Atrazine treatment. Noticeable suppression in expression level of all studied genes was accompanied with Atrazine treatment. N-Se, in its two concentrations with Atrazine causing a reduction in all severe effects of Atrazine and improving seedlings performance. Treatments with N-Se induced the expression of MT gene with increase in expression level alongside increase in the concentration of N-Se. This is one of rare studies that investigate the biological effects of N-Se in vivo anti-mutagenesis of Atrazine as well as a first record of Nano metalic particles N-Se as inducer for MT genes.

“…Jain et al, in the study they conducted with sugar cane plants exposed to selenium (Se), found that the MT gene was expressed at a higher level than all concentrations. However, they found that MT expression level increased up to a certain Se concentration and decreased after a certain Se concentration (Jain et al, 2015). In the study conducted by Tombuloğlu et al on the effect of boron element on the tomato plant, they found that MT gene expression level increased up to a certain concentration in root and shoot parts of the plant and but decreases after a certain concentration (Tombuloglu et al, 2012).…”

Oxidative stress caused by biotic and abiotic stress factors is the most important cause of cellular damage. Due to their sessile structures, plants have evolved regulatory mechanisms to respond to various environmental stresses The increased cellular concentration of reactive oxygen species is one of the major consequences of oxidative stress. including H2O2 production. Also, H2O2 is produced as a by-product of respiratory and photosynthetic metabolisms in plants. H2O2 acts as a multifaceted molecule because of its dual role in cells. It has been found to act as a secondary messenger in signal transmission networks. In this study, the changes in expression levels of stress-related genes and their relationship with H2O2 in pumpkin (Cucurbita pepo) plant exposed to Cd heavy metal at different durations and concentrations were investigated. As a result of this study, we concluded that the expression of stress-related genes may be related to the oxidative status of the cell and the concentration of H2O2 in the signaling mechanism, the expression of stress-related genes may be up-regulated to a certain degree of concentration, while a higher concentration of H2O2 may down-regulate the expression of the genes.
