Abstract

This study employed phytostabilized zinc sulfide (ZnS) nanocomposites, a novel and environmentally friendly material (orange peels), to mitigate arsenic (As) toxicity and its accumulation in wheat (Triticum aestivum L. cv. Pishgam). Wheat plants were exposed to sodium arsenate (via fertigation) at concentrations of 75 and 150 mg/L. These treatments caused significant reductions in shoots and roots biomass, chlorophyll contents; with concomitant higher tissue As levels, oxidative stress markers, along with enhanced antioxidant enzyme activity, compared to non-stressed controls. Supplementation with ZnS nanocomposites at concentrations of 75 and 150 mg/L significantly reduced As accumulation in both roots and shoots and alleviated the As toxicity. This was evidenced by increase of up to 29 % in shoot fresh weight, 76 % in root fresh weight, 27 % in foliar chlorophyll contents, 38 % in proline levels, and 21 % in total soluble protein contents. There was notable increase in zinc concentration (up to 122 %) and enzymatic activities (peroxidase (POD) increased by 98 %, ascorbate peroxidase (APX) by 28 %, and catalase (CAT) by 39 %) in plants exposed to ZnS nanocomposites levels of 75 and 150 mg/L compared to As-stressed counterparts. Furthermore, ZnS nanocomposites reduced the As accumulation in roots by up to 41 % and in shoots by up to 30 %, while enhanced the hydrogen peroxide (H₂O₂) level by 80 % under As stress. These findings highlighted the potential of ZnS nanocomposites (especially at 75 mg/L) as a phytostabilizing, non-toxic, and environmentally friendly solution to ameliorate As toxicity in wheat plants. This study further helps to enhance identify critical avenues for focusing on the integrated application of nanoparticles in soil management to promote sustainable agricultural practices.

植物稳定硫化锌纳米复合材料对砷胁迫下小麦生长和砷积累的影响

本研究采用植物稳定硫化锌（ZnS）纳米复合材料（橙皮）减轻小麦（Triticum aestivum L. cv）中砷（As）的毒性及其积累。Pishgam)。小麦植株暴露于浓度为75和150 mg/L的砷酸钠（通过施肥）下。这些处理导致茎、根生物量、叶绿素含量显著降低；与没有压力的对照组相比，伴随着更高的组织As水平，氧化应激标志物，以及增强的抗氧化酶活性。添加浓度为75和150 mg/L的ZnS纳米复合材料可显著降低根和芽As积累，减轻As毒性。茎部鲜重增加29%，根鲜重增加76%，叶面叶绿素含量增加27%，脯氨酸含量增加38%，可溶性总蛋白含量增加21%。与砷胁迫相比，暴露于75和150 mg/L ZnS纳米复合材料的植物锌浓度显著增加（高达122%），酶活性（过氧化物酶（POD）增加98%，抗坏血酸过氧化物酶（APX）增加28%，过氧化氢酶（CAT）增加39%）显著增加。此外，ZnS纳米复合材料在砷胁迫下可使根系As积累减少41%，使茎部As积累减少30%，使过氧化氢（H2O2）水平提高80%。这些发现突出了ZnS纳米复合材料（特别是在75 mg/L浓度下）作为一种植物稳定、无毒、环保的溶液来改善小麦植物砷毒性的潜力。这项研究进一步有助于确定关键途径，重点关注纳米颗粒在土壤管理中的综合应用，以促进可持续农业实践。

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
