Cadmium is a non-essential trace metal element with no known biological function. Cd toxic to both plants and human beings; hence, it of prime concern the scientific community. The objective this research find out effect heme oxygenase 1 on toxicity in Sorghum bicolor seedlings. Hydroponically adapted seedlings were treated various concentrations within range 10 200 μM. Seedlings harvested after 120 hours stress. cellular homeostasis tolerance mechanisms conducted evaluate growth parameters, stress parameters (MDA H2O2 content), non-enzymatic enzymatic (CAT, APX GPX) including HO 1. results showed that activity was measured be highest leaves at 150 μM CdCl2, which 29.61%.The correlated MDA content antioxidant enzymes concentration. revealed through decrease GPX CAT activities. Consequently, works cohort helps development plant's defense by scavenging ROS, confirmed time-dependent study. Accordingly, our highlighted might increase efficiency enhancing defence against S. bicolor.

Cadmium (Cd) is a highly toxic heavy metal that poses significant threat to food safety and agricultural production worldwide. Its solubility enables easy entry into plants, leading reductions in seed germination, growth crop yield. Thus, it crucial discover methods alleviate the harmful impact of Cd on plant growth. Magnetopriming (MP) non-invasive cost-effective technique has been proposed improve under abiotic stress conditions. The current study investigated potential MP early seedling biochemical responses soybean toxicity. Soybean seeds were magnetoprimed with static magnetic field (SMF) strength 200 mT for 1 hour before germination. unprimed grown different concentrations cadmium chloride (0, 25, 50, 75, 100, 300 μM CdCl2) Petri plates five days dark at 25 + 1°C. results revealed toxicity significantly reduced germination percentage inhibited parameters increased oxidative stress, as determined by malondialdehyde (MDA) content seedlings from seeds. inhibitory effect was increasing concentration Cd. However, remarkably percentage, parameters, activities total amylase protease, hydrogen peroxide (H2O2) decreased MDA proline germinating all These findings suggest can adverse effects increase tolerance index towards enhancing activity amylotic proteolytic enzymes reducing stress.

Cadmium (Cd) is a highly noxious, unnecessary and heavy metal element with no known biotic purpose. Cd harms not only plants but also humans by entering the food chain/web. Subsequently root system, it can be transported from vascular organs into leaves fruits, therefore becoming major global ecological health threat problem. Furthermost normal toxicity symptom inductive oxidative stress in plant cells. Nevertheless, have evolved several strategies to evade toxicity, primary out-turn of reactive oxygen or nitrogen species for signalling purposes. Understanding under would enable high uptake phytoremediation accumulation potential crop production. Hyperaccumulator plants' ability Cd-polluted soil has shown an effective option dealing pollutants.

None of our investigations have identified stress in response to the HSP70 and HO-1 proteins metals under study, which aimed understand genetic basis metal tolerance Arundo donax. Thus, present work investigate levels expression two important stress-related proteins, HSP70, A. donax after exposure various metals. The plants were collected from uncontaminated sites Abbottabad, Pakistan. Their rhizomes grown Hoagland solution, upon attaining suitable biomass, used effects on protein expression. treatments carried out with synthetic wastewater containing four Cr (0, 34, 66, 134, 267 mgL−1), namely, Cd, As, Pb, Cu Ni 25, 50, 75, 100 for three weeks. applied according a randomized block design (RBD) based hydroponics. selected was examined 10 days exposure. For studies, leaves separated following previously reported standard procedure. maximum level expressions noted at 66 mgL−1 Cr, then it slightly declined. Significantly, high observed Cd concentrations 50 mgL−1. Cu, As Ni, significantly 75 these showed linear increase increasing giant reed. It is clear research that may contribute plant stress, addition other possible mechanisms.

Arsenic (As) is a metal with potentially toxic effects on different organisms. Hydrogen sulfide (H 2 S) plays vital role in mitigating heavy toxicity by reducing oxidative stress plants and animals. However, the of H S alleviating arsenic yeast cells remains unclear. In this study, NaHS (exogenous physiological As-induced cell death was investigated. Yeast logarithmic phase were pretreated 0.05 mmol/L for 6 h, then incubated YPD medium or without 1 As. After 12 h treatment, relative survival rate, content, biomarkers, antioxidant machinery measured. Our results showed that sodium arsenite-induced pretreatment significantly alleviated death. Under arsenite conditions, levels intracellular reactive oxygen species (ROS) malondialdehyde (MDA) increased, accompanied inhibition catalase (CAT) activity downregulation CTT1 expression. activities superoxide dismutase (SOD) glutathion peroxidase (GPX) expression SOD1 GPX2 markedly upregulated group treated arsenite. When NaHS, ROS MDA decreased significantly, SOD, CAT, GPX increased significantly. This associated significant increase rate content compared to treatment alone. findings indicate alleviates death, mainly enhancing defense system.
