Effects of exogenous amino acids on yttrium uptake and accumulation in tomato ( Solanum lycopersicum )

International Journal of Phytoremediation, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 9

Published: March 4, 2025

This study investigated the impacts of exogenous amino acid supplementation on uptake, translocation, and accumulation yttrium (Y) in tomato plants (Solanum lycopersicum). To understand how acids enhance nutrient uptake plant growth by using Hoagland solution. The results indicated that combination Y with glutamic (Y + Glu) significantly increased concentration leaves to 28.5 ± 1.42 µg g-1, while histidine His) resulted a markedly lower 2.7 0.06 g-1. Notably, proved be particularly effective enhancing xylem sap. control exhibited higher sap flow rate 0.27 0.008 g h-1, which was greater than those treated (p < 0.05). Histidine levels were elevated His treatment, reaching 194.78 13.79 μmol L-1, tryptophan aspartic showed their highest concentrations respective treatments at 109.92 14.43 L-1 212.95 13.65 L-1. These findings demonstrated substantially enhanced phytoextraction plants, through application acid. Further exploration into molecular mechanisms governing complexation transport within phytoremediation is needed.

An Experimental Assessment of Miscanthus x giganteus for Landfill Leachate Treatment: A Case Study of the Grebača Landfill in Obrenovac

Processes, Journal Year: 2025, Volume and Issue: 13(3), P. 768 - 768

Published: March 7, 2025

Water pollution caused by landfill leachate, which contains high concentrations of heavy metals and organic contaminants, poses a serious environmental threat. Among the potential remediation strategies, phytoremediation using Miscanthus x giganteus (giant miscanthus) has gained attention due to its strong resistance harsh conditions capacity accumulate metals. This study evaluates effectiveness in treating with focus on removing key pollutants such as zinc (Zn), nickel (Ni), copper (Cu) simulating wetland conditions. A pilot-scale experiment conducted at Grebača site assessed plant’s ability enhance metal bioavailability, stabilize limit their mobility within leachate system. The results demonstrated that effectively mobilized Zn Ni through rhizospheric activity, whereas Cu remained largely immobile, indicating for phytostabilization. Sequential extraction analysis further confirmed plant significantly reduced mobile fractions soil, highlighting dual role both These findings suggest offers sustainable cost-effective approach treatment, serving viable alternative conventional methods. By integrating this nature-based solution into industrial municipal waste management, it promotes sustainability while enhancing efficiency.

Effects of planting patterns on physicochemical properties, metabolites and microbial community structure of rhizosphere soil in perennial cultivated grassland

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: April 8, 2025

Establishing perennial cultivated grasslands on the Qinghai-Tibet Plateau helps address seasonal imbalance of forage resources and supports restoration degraded grasslands. The most common planting patterns-monocropping mixed cropping-are well-studied in terms vegetation structure, productivity, soil nutrients. Despite their significance, influence prolonged practices underground microbial communities metabolites has often been neglected. In this study, two characteristic plants, Festuca sinensis 'Qinghai' Poa pratensis 'Qinghai', from area around Qinghai Lake were selected as experimental subjects by employing 16 S ITS sequencing methods conjunction with non-targeted metabolomics analysis. effects patterns (monocropping cropping) rhizosphere characteristics, community structure examined. results showed that compared monocropping, cropping significantly increased contents nutrients key metabolites. addition, it had a greater impact fungal diversity than bacterial diversity, particularly β-diversity. While α-diversity dominant phyla remained stable, fungi more responsive to changes properties These show new niche differentiation between different species grassland stimulates secretion trehalose valine, which further affects enhances ecological functions findings will guide selection strategies improve local sustainable productivity.
