“…Tow transcripts of heavy metal transport detoxification superfamily were expressed, that is involved in mineral accumulation and transportation only (Table 3). In addition, protein family such as abscisic stress ripening proteins (1), heat shock protein family (16), heat stress transcription factor (15), chloroplast enhancing stress protein (1) and WRKY transcription factors (1) are functionally involved in response to STR [Gupta et al 2018; Gupta et al 2019].…”

Development of Zinc (Zn), Iron (Fe) and other minerals rich grains along with various stress tolerance and susceptible (STR) wheat genotype, will help to reduce globally spread malnutrition problem. Current study deals with transcriptome profiling of 4 high- and 3 low- Zn & Fe accumulating wheat genotypes (HZFWGs) and (LZFWGs). Functional characterization of expressed and high and low specific genes, accompanied by metabolic pathways analysis reveals, phenylpropanoid biosynthesis, and other associated pathways are mainly participating in plant stress defense mechanism in both genotypes. Chlorophyll synthesis, Zn & Fe binding, metal ion transport, and ATP-Synthase coupled transport mechanism are highly active in HZFWGs while in LZFWGs ribosomal formation, biomolecules binding activities and secondary metabolite biosynthesis. Transcripts accountable for minerals uptake and purine metabolism in HZFWGs are highly enriched. Identified transcripts may be used for marker-assisted selection and breeding to develop minerals rich crops.

“…Essential metals (Mn, Cu, Zn, Fe, Mg, Co, Se, Cr, Mo, and Ni) are used to generate physical activities such as cofactor in oxidation-reduction reactions. Non-essential metals (Cd, As, Pb, Hg, Sb, and Ag) disrupt the enzymatic reactions due to their interaction with thiol groups [12].…”

In the present study, concentration effects of different heavy metals (Pb and Mg) in Rosa indica are observed to detect the changes in growth response due to effect of metal’s toxicity. Both metals have different tolerance index. Lead is toxic metal and has small tolerance index, whereas Mg is a macronutrient having a high tolerance index which can move in a large scale to different parts of the plants. The least and highest accumulation values of Pb and Mg were observed as 0.608-25.897 mg/L and 20948-52291 mg/L, respectively. The toxicity order in rose plant is Pb>Mg. The bio concentration and translocation factor values of Pb and Mg were 0.97, 0.77, 0.93 and 0.9 respectively. In lead polluted soil, plants height shown is declined due to the concentration of lead (66.38 cm-56.48 cm) whereas plant height increased because of massive concentrations of Mg (63.93 cm-75.03 cm). Results `revealed that accumulation of both metals were excessive in the roots and least in the stem and leaves. It is concluded that rose plant is a good accumulator of lead and magnesium.

“…The industrial development has resulted in constantly increasing levels of heavy metal contamination in the environment [ 1 , 2 ]. To reduce environmental pollution, it is necessary to determine heavy metal ions in soil [ 3 , 4 ] and water resources [ 5 , 6 ]. The detection and selective quantitative definition of heavy metal ions in nature-conservation resources or biological samples have been an important research area for a long time.…”

Magneto-Fluorescent Hybrid Sensor CaCO3-Fe3O4-AgInS2/ZnS for the Detection of Heavy Metal Ions in Aqueous Media

Heavy metal ions are not subject to biodegradation and could cause the environmental pollution of natural resources and water. Many of the heavy metals are highly toxic and dangerous to human health, even at a minimum amount. This work considered an optical method for detecting heavy metal ions using colloidal luminescent semiconductor quantum dots (QDs). Over the past decade, QDs have been used in the development of sensitive fluorescence sensors for ions of heavy metal. In this work, we combined the fluorescent properties of AgInS2/ZnS ternary QDs and the magnetism of superparamagnetic Fe3O4 nanoparticles embedded in a matrix of porous calcium carbonate microspheres for the detection of toxic ions of heavy metal: Co2+, Ni2+, and Pb2+. We demonstrate a relationship between the level of quenching of the photoluminescence of sensors under exposure to the heavy metal ions and the concentration of these ions, allowing their detection in aqueous solutions at concentrations of Co2+, Ni2+, and Pb2+ as low as ≈0.01 ppm, ≈0.1 ppm, and ≈0.01 ppm, respectively. It also has importance for application of the ability to concentrate and extract the sensor with analytes from the solution using a magnetic field.
