ROS detoxification is an essential process in protecting plant cells and their organelles, which is caused by ROS generated in stress condition. Peroxidase (POD) isozyme, Malondialdehyde (MDA) content, and Ascorbate peroxidase (APX) activity are the indicators of plants for measuring pollution effects. The purpose of the present study was to investigate Cd-induced stress on POD isozymes, MDA co...

Sedum alfredii is a well-known Cd (cadmium) hyperaccumulator native to China. The impacts of exogenous Ca on Cd-induced oxidative stress and antioxidant systems in roots of S. alfredii were investigated by using cellular and biochemical approaches. Supplementation of the medium with higher Ca levels resulted in alleviated growth inhibition and decreased Cd concentration, as well as increased Ca...

Populus yunnanensis was employed as a model species to detect sexual differences in growth, physiological, biochemical, and ultrastructural responses to cadmium (Cd) stress, nitrogen (N) deposition, and their combination. Compared with the control conditions, Cd decreased plant biomass, damaged the photosynthetic apparatus, visible as a decreased maximum efficiency of photosystem II (PSII; F(v)...

OBJECTIVE The purpose of this study was to investigate on relationship between spiritual intelligence, resilience, and perceived stress. METHODS The study sample consisted of 307 students of Sistan and Baluchistan University. The Connor-Davidson Resilience Scale (CD-RISC), the Spiritual Intelligence Self-Report Inventory (SISRI) and the Perceived Stress Scale (PSS) are used as a research inst...

MicroRNAs (miRNAs) play important roles in plant responses to environmental stress. In this work, we used high-throughput sequencing to analyze transcriptome and small RNAs (sRNAs) in Typha angustifolia under cadmium (Cd) stress. 57,608,230 raw reads were obtained from deep sequencing of a pooled cDNA library. Sequence assembly and analysis yielded 102,473 unigenes. We subsequently sequenced tw...

Cadmium (Cd) has been recognised as one of the most important environmental and industrial pollutants, and up-to-date investigations have shown that one of the mechanisms of its toxicity is associated with the induction of oxidative stress. The aim of this study was to determine the connection between acute oral and intraperitoneal exposure to Cd and parameters indicative of oxidative stress in...

BACKGROUND AND AIMS Cadmium (Cd) is a non-essential trace element that elicits oxidative stress. Plants respond to Cd toxicity via increasing their Cd-chelating and antioxidative capacities. They predominantly chelate Cd via glutathione (GSH) and phytochelatins (PCs), while antioxidative defence is mainly based on the use and recycling of both GSH and ascorbate (AsA), complemented by superoxide...

Cadmium (Cd) and selenium (Se) could jointly affect plant growth. To investigate the of Se on Cd accumulation in Juglans regia physiological mechanism by which regulates Cd-induced oxidative stress, this study, effects different foliar application doses (0 (Se0), 20 (Se20), 200 (Se200) ?M) J. (variety Xinfeng) seedlings under stress (5 mM) were determined. The results show that exogenous (Se20 ...

Metabolic responses to cadmium (Cd) may be associated with variations in Cd tolerance in plants. The objectives of this study were to examine changes in metabolic profiles in bermudagrass in response to Cd stress and to identify predominant metabolites associated with differential Cd tolerance using gas chromatography-mass spectrometry. Two genotypes of bermudagrass with contrasting Cd toleranc...
