The present study investigates the impact of varying concentrations PVC microplastics (PVC–MPs) – specifically 0 (no PVC–MPs), 2, and 4 mg L− 1 –alongside different arsenic (As) levels As), 150, 300 kg− in soil, with concurrent application copper oxide–nanoparticles (CuO–NPs) at CuO –NPs), 25 50 µg mL− to barley (Hordeum vulgare L.) plants. This research primarily aims assess plant growth biomass, photosynthetic pigments gas exchange characteristics, oxidative stress indicators, as well response various antioxidants (both enzymatic non-enzymatic) their relevant genes expression, proline metabolism, AsA–GSH cycle, cellular fractionation within findings showed that increased PVC–MPs As soil significantly reduced pigments, characteristics. Additionally, roots shoots, evidenced by elevated malondialdehyde (MDA), hydrogen peroxide (H2O2), electrolyte leakage (EL), which turn stimulated production non-enzymatic antioxidants, gene sugar content. Furthermore, a notable increase pigmentation was observed. Conversely, CuO–NPs resulted substantial improvement activity along reduction stress. enhanced while decreasing metabolism AsA-GSH cycle H. These outcomes provide new insights into sustainable agricultural practices offer significant potential addressing critical challenges heavy metal contamination soils.

In recent years, the use of priming agents, such as silicon, melatonin, salicylic acid, glycine betaine, and ascorbic acid has gained significant attention for their role in mitigating abiotic stresses across various plant species. While previous research been conducted on individual impact metal stress resistance among crop species, combined effects context heavy stressed conditions remain underexplored. Wheat (Triticum aestivum L.) seedlings was grown under toxic concentration copper (Cu) i.e., 100 µM which were applied with hydroponic 21 days. The outcomes indicated that Cu nutrient solution notably reduced growth biomass, photosynthetic pigments, gas exchange attributes. However, also induced oxidative plants by increasing malondialdehyde (MDA), hydrogen peroxide (H2O2) increased compounds enzymatic non-enzymatic antioxidants, health risk index (HRI) gene expression sugar content. Furthermore, a increase proline metabolism, AsA-GSH cycle, pigmentation cellular components observed. Although, application different showed characteristics, compounds, decreased HRI. addition, agents enhanced fractionation metabolism cycle T. seedlings. These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges contamination agricultural soils.

Rice is a globally important food crop which sensitive to the presence of metalloid, arsenic (As). There limited research pertaining identifying relevant As-tolerant rice germplasm in adaptive breeding initiatives, despite fact that As contamination has long been known. This study served identify growth performance different genotypes under high levels As. seed germination analysis (germination percentage, GP) was performed categorize eight and growing varying including As25, 25 μM As50, 50 μM. The Zhenong 41 identified as highly tolerant with lowest decrease GP by 87 %, plant height (PH) 26 dry weight (DW) 16 %; while 9311 observed be most genotype highest reduction 44 PH 48 % DW 54 As25 stress conditions, compared control treatment. higher As50 treatment delivered more adverse inhibitory effects than plants cultivated As25. Specifically, As-sensitive showed significantly foliar chlorophyll contents relative other genotypes, especially (As-tolerant). During exposure levels, modulated augmented production MDA H2O2 stimulating activities POD, SOD, CAT. revealed interesting insights into responses variable stresses throughout various stages. Overall, findings this could harnessed support any ongoing agendas for cultivation As-polluted environments.

In the current industrial scenario, vanadium (V) as a metal is of great importance but poses major threat to ecosystem. present study, effect toxic concentration V, i.e., 10 µM in soil on growth, photosynthetic pigments, gas exchange characteristics, oxidative stress biomarkers, antioxidants machinery (enzymatic and non-enzymatic antioxidants), ions uptake, proline metabolism, V uptake different parts plant was investigated with without exogenous application selenium (Se) 5 V-stressed rice (Oryza sativa L.). Our results depicted that addition significantly (P < 0.05) decreased growth biomass, attributes, minerals by O. compared plants grown V. However, toxicity boosted production reactive oxygen species (ROS) increasing contents malondialdehyde (MDA), which indication also manifested hydrogen peroxide (H2O2) membrane-bounded organelles. Although activities various antioxidative enzymes like superoxidase dismutase (SOD), peroxidase (POD), catalase (CAT), ascorbate (APX) their gene expression Fe-SOD, POD, CAT, APX phenolic, flavonoid, ascorbic acid, anthocyanin metabolism proline, pyrroline5-carboxylate, pyrroline-5-carboxylate reductase, dehydrogenase were increased due stress. illustrated Se seedlings antioxidant capacity and, thus, improved seedlings, those not artificially supplied Se. Research findings, therefore, suggested can ameliorate result composition under balanced exudation nutrient effluxes. This study provides novel insights into role mitigating vanadium-induced rice, thereby offering promising approach enhancing crop resilience metal-contaminated soils advancing sustainable agricultural practices.
