“…Fresh weight and length of shoots ( Figure 1) and photosynthetic pigments ( Figure 2A) were significantly decreased by the UV-B treatment. This was expected since similar effects were established previously in pea, wheat, bean, and Indian mustard plants (Alexieva et al, 2001;Singh et al, 2011;Li et al, 2012;Pandey et al, 2012). Additionally, when Biomin was added to the nutrient medium, the harmful effects of UV-B decreased.…”

A natural substance extracted from coal with humic acids as its active ingredients, namely Biomin, was added to nutrient medium and applied to triticale roots 3 days prior to UV-B irradiation treatment. UV-B treatment increased malondialdehyde and anthocyanin contents and the activities of peroxidase and superoxide dismutase, while it decreased chlorophyll content, fresh weight, and shoot length. Catalase and total phenolics content did not change in UV-B-treated shoots. The pretreatment with Biomin showed favorable effects on growth, decreased the oxidative damage provoked by UV-B irradiation, increased the content of UV-B-absorbing compounds, and positively influenced enzymatic activities. The application of Biomin on triticale plants was beneficial for counteracting the UV-B-induced oxidative stress by increasing the content of nonenzymatic antioxidants and antioxidant enzyme activities involved in detoxification of reactive oxygen species.

“…The membrane lipid perturbation can also be performed by a range of other abiotic stress factors such as UV radiation, temperature extremes, nutrient deficiency, air pollution, and chemical toxicants (Gill and Tuteja 2010;Yan et al 2010;Tripathi et al 2011;Li et al 2012;Szarka et al 2012;Bashir et al 2014;Majid et al 2014). The contribution of membrane lipids, particularly the unsaturated membrane lipids, in protecting the photosynthetic machinery from photoinhibition under cold conditions has been intensively discussed (Nishida and Murata 1996).…”

Stress factors provoke enhanced production of reactive oxygen species (ROS) in plants. ROS that escape antioxidant-mediated scavenging/detoxification react with biomolecules such as cellular lipids and proteins and cause irreversible damage to the structure of these molecules, initiate their oxidation, and subsequently inactivate key cellular functions. The lipid- and protein-oxidation products are considered as the significant oxidative stress biomarkers in stressed plants. Also, there exists an abundance of information on the abiotic stress-mediated elevations in the generation of ROS, and the modulation of lipid and protein oxidation in abiotic stressed plants. However, the available literature reflects a wide information gap on the mechanisms underlying lipid- and protein-oxidation processes, major techniques for the determination of lipid- and protein-oxidation products, and on critical cross-talks among these aspects. Based on recent reports, this article (a) introduces ROS and highlights their relationship with abiotic stress-caused consequences in crop plants, (b) examines critically the various physiological/biochemical aspects of oxidative damage to lipids (membrane lipids) and proteins in stressed crop plants, (c) summarizes the principles of current technologies used to evaluate the extent of lipid and protein oxidation, (d) synthesizes major outcomes of studies on lipid and protein oxidation in plants under abiotic stress, and finally, (e) considers a brief cross-talk on the ROS-accrued lipid and protein oxidation, pointing to the aspects unexplored so far.

“…In most studies, soybean Cd levels were considerably higher in roots, stems, leaves, or pods than in seeds. Moreover, a high soil Cd concentration is also toxic to soybean reducing plant growth and photosynthesis apart from other effects [31]. Due to genetic differences in soybean cultivar for seed Cd accumulation, a three-to sixfold Cd concentration increase was observed between lowest and highest accumulating genotypes.…”

Cadmium (Cd) is a chemical element present in the soil. At high concentrations Cd can cause physiological and morphological damages to plants and it is highly toxic to human beings. Minimizing the intake of Cd and other heavy metals from food consumption is an important health issue. Efforts have been made to identify genetic elements that are involved in Cd detoxification in plants. Heavy metal transporter 3 (HMA3) plays a role in sequestration of Cd into vacuoles in soybean (Glycine max). Inheritance studies revealed that low Cd accumulation in soybean seed is controlled by a major gene (Cda1) with the allele for low accumulation being dominant. Major QTL for seed Cd accumulation, Cda1 and cd1, have been identified independently for low Cd accumulation and both mapped to the same location as on LG-K (Chromosome 9) with simple sequence repeat (SSR) markers. A single nucleotide substitution causing a loss of function of the ATPase was found. The SSR markers linked to the Cda1 and Cd1gene(s)/or QTLs and the SNP marker in the P1B-ATPase metal ion transporter gene in soybean can be utilized in marker assisted selection (MAS) for developing food grade soybean varieties.
