Comparative toxicity of copper and zinc contaminated wastewater irrigation on growth, physiology, and mineral absorption of wheat

Water Environment Research, Journal Year: 2025, Volume and Issue: 97(1)

Published: Jan. 1, 2025

Abstract A comparative pot study was performed to assess the toxic effects of copper (Cu) and/or zinc (Zn) contaminated wastewater (WW) irrigation on growth, physiology, and element concentration wheat grown for two months. The treatments included with uncontaminated as control, Cu‐contaminated WW (CuWW), Zn‐contaminated (ZnWW), Cu + Zn (CuZnWW) in a completely randomized design. Compared ZnWW, CuWW or CuZnWW had severe mineral absorption by wheat. Irrigation reduced shoot length, root dry weights 44–45%, 54–56%, 5–6%, 33–34%, respectively, against control. Similarly, these diminished chlorophyll a, b, carotenoids, SPAD 59–60%, 49–51%, 26–27%, respectively. Conversely, improved total polyphenols, polyphenolic acids, flavonoids, antiradical activity, however, maximum increase parameters up 65% observed when irrigated ZnWW. Pearson correlation showed that decline growth physiology negatively correlated metal uptake. Dehydrogenase activity is severely hampered lesser extent ZnWW well. These results suggest adversely affects found be less crops than Cu. Thereby, this data highlights need tailored approach prioritize lower toxicity during use practice. Practitioner Points (20 ppm Cu) substantially (80 ppm) compared Wheat increased biologically active compounds shoot. Contaminated affected minerals part soil wastewater. leftover crop residues resulted accumulation organic matter soil.

The Synthesis of Selenium Nanoparticles and Their Applications in Enhancing Plant Stress Resistance: A Review

Nanomaterials, Journal Year: 2025, Volume and Issue: 15(4), P. 301 - 301

Published: Feb. 16, 2025

Nanoparticle-based strategies have emerged as transformative tools for addressing critical challenges in sustainable agriculture, offering precise modulation of plant-environment interactions through enhanced biocompatibility and stimuli-responsive delivery mechanisms. Among these innovations, selenium nanoparticles (SeNPs) present unique advantages due to their dual functionality both essential micronutrient carriers redox homeostasis modulators. Compared conventional treatments, SeNPs offer a more efficient environmentally friendly solution improving plant resilience while minimizing toxicity, even at low doses. This review provides comprehensive analysis methods synthesizing SeNPs, including chemical reduction, green synthesis using extracts, biological techniques with microbial agents. Additionally, the discusses effects on biotic abiotic stress responses plants, focusing how activate stress-response pathways enhance immune function. The primary objective this study is theoretical insights into application modern such crop yield quality under conditions. Moreover, research highlights role advancing agricultural practices by reducing reliance fertilizers pesticides. findings underscore potential management, contributing eco-friendly future.

Selenium seed priming enhanced the growth of salt-stressed Brassica rapa L. through improving plant nutrition and the antioxidant system

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 13

Various abiotic stresses may affect the germination, growth, and yield of direct-seeded vegetable crops. Seed priming with effective antioxidant mediators alleviate these environmental by maintaining uniformity in seed germination improving subsequent health developing seedlings. Salt-induced stress has become a limiting factor for successful cultivation Brassica rapa L., especially Southeast Asian countries. The present study was performed to elucidate efficacy using selenium (Se) mitigating salt-induced oxidative turnip crops reducing uptake Na+. In this study, we administered three different levels Se (Se-1, 75 μmol L-1; Se-2, 100 Se-3, 125 L-1) alone or combination NaCl (200 mM). Conspicuously, salinity Se-2 modulated expression genes, including catalase (CAT), peroxidase (POD), superoxide dismutase (SOD), ascorbate (APX). upregulated stress-responsive genes alleviated salt scavenging higher reactive oxygen species (ROS) level. ameliorative potential (Se-2 = enhanced final percentage, photosynthetic content, seedling biomass production up 48%, 56%, 51%, respectively, under stress. advantageous effects were attributed alleviation through reduction malondialdehyde (MDA), proline, H2O2.

The intertwining of Zn-finger motifs and abiotic stress tolerance in plants: Current status and future prospects

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 13

Environmental stresses such as drought, high salinity, and low temperature can adversely modulate the field crop’s ability by altering morphological, physiological, biochemical processes of plants. It is estimated that about 50% + productivity several crops limited due to various types abiotic either presence alone or in combination (s). However, there are two ways plants survive against these stresses; a) through management practices b) adaptive mechanisms tolerate These tolerant mostly linked their signalling transduction pathway, triggering action plant transcription factors controlling expression stress-regulated genes. In recent times, studies found Zn-finger motifs have a significant function during stress response first report, wide range Zn-binding has been recognized termed Zn-fingers.
