Abstract In present years, the use of zinc oxide nanoparticles (ZnO‐NPs) has received great attention due to increase in nutrient accumulation by plants for improving capability agronomic Zn biofortification. Although, emergence polyvinyl chloride (PVC) microplastics (MPs) as pollutants agricultural soils is increasingly alarming, presenting significant toxic threats soil ecosystems. The work studied impact different levels PVC‐MPs, namely 0 (no PVC‐MPs), 2, and 4 mg L −1 , along with mercury (Hg) Hg), 10, 25 kg soil, while concurrently applying ZnO‐NPs at ZnO‐NPs), 50, 100 μg mL rye ( Secale cereale L.) plants. This study aimed examine plant growth biomass, photosynthetic pigments gas exchange characteristics, oxidative stress indicators, response various antioxidants (enzymatic non‐enzymatic) their specific gene expression, proline metabolism, ascorbic acid–dehydroascorbic acid (AsA–GSH) cycle, cellular fractionation research outcomes indicated that elevated PVC‐MPs Hg notably reduced pigments, attributes. However, also induced roots shoots increasing malondialdehyde (MDA), hydrogen peroxide (H 2 O ), electrolyte leakage (EL) which increased compounds enzymatic non‐enzymatic antioxidants, expression sugar content. Furthermore, a AsA–GSH pigmentation components was observed. application showed compounds, decreased stress. addition, enhanced metabolism cycle S . These results open new insights sustainable agriculture practices hold immense promise addressing pressing challenges heavy metal contamination soils.

Effect of Arsenic Soil Contamination on Stress Response Metabolites, 5-Methylcytosine Level and CDC25 Expression in Spinach

Toxics, Journal Year: 2023, Volume and Issue: 11(7), P. 568 - 568

Experimental spinach plants grown in soil with (5, 10 and 20 ppm) arsenic (As) contamination were sampled 21 days after As(V) contamination. Levels of As samples (from 0.31 ± 0.06 µg g-1 to 302.69 11.83 g-1) higher roots lower leaves, which indicates a low ability translocate into leaves. Species arsenic, As(III) As(V), represented favor the (III) specie contaminated variants, suggesting enzymatic arsenate reduction. In relation predominant accumulation roots, changes malondialdehyde levels observed mainly where they decreased significantly growing 11.97 0.54 control 2.35 0.43 ppm As). Higher values than leaves case 5-methylcytosine (5-mC). Despite that, change 5-mC by was further deepened 0.20 14.10%). spinach, expression CDC25 gene increased highest compared control. total phenolic content, flavonoid acids content antioxidant capacity all values, unlike roots.
