The increase in industrialization has led to an exponential heavy metal (HM) soil contamination, which poses a serious threat public health and ecosystem stability. This review emphasizes the urgent need develop innovative technologies for environmental remediation of intensive anthropogenic pollution. Phytoremediation is sustainable cost-effective approach detoxification contaminated soils using various plant species. discusses detail basic principles phytoremediation its ecological advantages over other methods cleaning areas technical viability. Much attention been given selection hyperaccumulator plants that can grow on metal-contaminated soils, biochemical mechanisms allow these isolate, detoxify, accumulate metals are discussed detail. novelty our study lies reviewing plant–microorganism interactions greatly enhance efficiency as well discussing genetic modifications could revolutionize cleanup soils. Moreover, this manuscript potential applications beyond detoxification, including role bioenergy production biodiversity restoration degraded habitats. concludes by listing problems result from pollution future generations still overcome suggests promising research directions integration nano- biotechnology will play important enhancing effectiveness phytoremediation. These contributions critical scientists, policy makers, practitioners seeking utilize maintain stability environment restoration.

Arabidopsis MEB3 functions as a vacuolar metal transporter to regulate iron accumulation in roots

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Март 6, 2025

Iron is an essential nutrient for plant photosynthesis and development, but excess iron leads to stress. After absorption from the soil, plants store in roots distribute it shoots via long-distance transport. The vacuole involved storage maintenance of cellular homeostasis, vacuolar transporter (VIT) family proteins have been identified as transporters. However, contribution transporters overall homeostasis not fully understood. Here, we show that MEMBRANE PROTEIN OF ER BODY 3 (MEB3), a VIT member, functions metal distribution Arabidopsis thaliana. Heterologous expression MEB3 yeast or zinc mutants restored iron- zinc-resistance phenotypes respective mutants, indicating regulates In Arabidopsis, was expressed almost all tissues, albeit higher levels seedlings, protein localized tonoplast. were reduced meb3 knockout mutant roots, suggesting capacity roots. At high concentration, accumulated more less than wild type, impairment proper mutants. These findings demonstrate other metals plants.

Multi-Scale Tolerance Mechanisms of Xanthium strumarium L. Under Lead Stress and Its Application in Phytoremediation

Plants, Год журнала: 2025, Номер 14(9), С. 1307 - 1307

Опубликована: Апрель 26, 2025

Heavy metal pollution poses a global environmental challenge, with lead (Pb) being particularly concerning due to its persistence and toxicity. This study investigated Xanthium strumarium L. from China's Yellow River Sanmenxia section through hydroponic experiments (0-600 mg/L Pb2+, 1-11 d exposure) elucidate Pb2+ response mechanisms. Integrated analyses (EDX, FTIR, thermogravimetry, hyperspectral imaging) revealed three-phase sequestration strategy: the roots immobilized 88.55% of Pb pectin carboxyl de-esterification lignin-Pb complexation, while stems leaves retained <11.14% <0.31%, respectively. A critical threshold (300 mg/L) triggered nonlinear accumulation escalation. Thermogravimetric analysis demonstrated enhanced cell wall stability under stress (66.7% residual carbon increase at 600 mg/L). Hyperspectral features (1670 nm band intensity) effectively tracked physiological dynamics. The findings establish X. strumarium's superior suitability for root-based immobilization rather than phytoextraction in Pb-contaminated sites, low translocation efficiency minimizing ecological risks. identified concentration spectral biomarkers provide multi-scale insights optimizing situ phytostabilization strategies, advancing both theoretical understandings practical applications heavy remediation.

Vacuolar Iron Transporter (VIT) genes have been characterized and indicated to play critical roles in iron homeostasis various plants. Heavy metals pose a significant challenge bean cultivation, necessitating the development of heavy metal-resistant cultivars as key strategy mitigate their impacts. detoxification is crucial for plants survive adapt adverse environment caused by metal stress. The current study used bioinformatic tools characterize VIT gene bean, member legume family an important agricultural product, first time. identified 11 (PhvulVIT-1–PhvulVIT-11) bean's genome. These displayed molecular weights (MW) ranging from 16.48 28.92 kDa comprised 155–269 amino acid residues. distribution PhvulVIT on four chromosomes was not homogeneous, eight were observed be located chromosome 2. Gene duplication events suggested purifying selection primary evolutionary force, ensuring functional stability duplicated genes. Phylogenetic analysis classified into three clades, reflecting relationships with orthologs Arabidopsis thaliana Glycine max. Cis-regulatory element promoter regions revealed stress-responsive motifs like MYB, MYC, ABRE, which are essential plant responses environmental stresses phytohormone signaling. Additionally, expression patterns under conditions examined using RNAseq. This enhances our understanding nutrient stress adaptation, offering valuable insights crop improvement strategies, including biofortification stress-tolerant cultivars.
