“…It has been demonstrated that Cd can interfere with the uptake, transport and the use of some nutrients elements (e.g., ca, P, K, etc.) and water by plants [2]. Cadmium can also reduce plant cellular activities due to the generation of oxidative stress and the inhibition of the enzyme activity [29].…”

Accumulation of heavy metals in the ecosystem and their toxic effects through food chain can cause serious ecological and health problems. In the present study, experiments were performed to understand how the addition of magnetite (Fe 3 O 4 ) nanoparticles reduces the toxicity caused by Cd, Pb, Cu, and Zn in cucumber plants. Plant growth parameters, lipid peroxidation, and antioxidant enzymes were measured in seedling samples treated with either metals or metals supplemented with Fe 3 O 4 to demonstrate the reduction in metal-induced oxidative stress conferred by Fe 3 O 4 . Results showed that the toxic effect of metals on seedling growth parameters can be arranged in the rank order of inhibition as follows: Cu > Cd > Zn > Pb. Exposure to metals significantly decreased the seedlings growth, the activities of superoxide dismutase (SOD) and peroxidases (POD), while the malondialdehyde (MDA) content significantly increased in cucumber seedlings. The reducing activity of nano-Fe 3 O 4 against heavy metals stresses was confirmed in this study by the decrease in MDA content. The correlation between the decrease of MDA concentration and the increase in SOD and POD activities in the presence of nano-Fe 3 O 4 suggest that the MDA reduction in the tested seedlings can result from the increased enzyme activity.

Abstract-No study have existed on heavy metals present in the river of Iloilo Batiano, Philippines. Thus, this study was conducted to determine the presence and quantities of heavy metals specifically cadmium, chromium and lead in the sediments of Iloilo Batiano River. Furthermore, water physicochemical parameters were determined such as pH and temperature, in situ. Three sampling stations were identified adjacent to (1) Batiano Bridge of Oton, Iloilo; (2) Sto. Niño Bridge of Villa, Iloilo City and (3) Calumpang Bridge of Molo, Iloilo City, respectively. Three (two sides and at the center perpendicular to the river) 500 g surface sediments were collected in each of the sampling station for a total of nine sediment samples stored in a sterile ziplock and were immediately transported at the CAS-ASL of UPV, Miag-ao, Iloilo for the quantification of metals through flame atomic absorption spectrophotometry (FAAS). Available cadmium was below detection limit and it appeared that available Pb > Cr in the three points of the river in the three sampling stations. Available chromium and lead have high accumulation in station three (Calumpang Bridge). This study provides information on the heavy metal status of the river, awareness to the public and for further conservation of the river.

“…This diverse collection of sorghum germplasm contains genetic variation with undiscovered impact on seed element composition (Das et al, 1997). Mapping quantitative trait loci for seed element concentration has been successful in a number of species, including Arabidopsis (Arabidopsis thaliana; Vreugdenhil et al, 2004;Waters and Grusak, 2008;Buescher et al, 2010), rice (Oryza sativa; Norton et al, 2010;Zhang et al, 2014), wheat (Triticum aestivum; Shi et al, 2008;Peleg et al, 2009), and maize (Zea mays; Simic et al, 2012;Baxter et al, 2013Baxter et al, , 2014.…”

Integration of Experiments across Diverse Environments Identifies the Genetic Determinants of Variation in Sorghum bicolor Seed Element Composition

Seedling establishment and seed nutritional quality require the sequestration of sufficient element nutrients. The identification of genes and alleles that modify element content in the grains of cereals, including sorghum (Sorghum bicolor), is fundamental to developing breeding and selection methods aimed at increasing bioavailable element content and improving crop growth. We have developed a high-throughput work flow for the simultaneous measurement of multiple elements in sorghum seeds. We measured seed element levels in the genotyped Sorghum Association Panel, representing all major cultivated sorghum races from diverse geographic and climatic regions, and mapped alleles contributing to seed element variation across three environments by genome-wide association. We observed significant phenotypic and genetic correlation between several elements across multiple years and diverse environments. The power of combining high-precision measurements with genome-wide association was demonstrated by implementing rank transformation and a multilocus mixed model to map alleles controlling 20 element traits, identifying 255 loci affecting the sorghum seed ionome. Sequence similarity to genes characterized in previous studies identified likely causative genes for the accumulation of zinc, manganese, nickel, calcium, and cadmium in sorghum seeds. In addition to strong candidates for these five elements, we provide a list of candidate loci for several other elements. Our approach enabled the identification of single-nucleotide polymorphisms in strong linkage disequilibrium with causative polymorphisms that can be evaluated in targeted selection strategies for plant breeding and improvement.
