Heliyon, Год журнала: 2024, Номер 10(6), С. e27724 - e27724

Опубликована: Март 1, 2024

Lead (Pb) is a highly toxic contaminant that ubiquitously present in the ecosystem and poses severe environmental issues, including hazards to soil-plant systems. This review focuses on uptake, accumulation, translocation of Pb metallic ions their toxicological effects plant morpho-physiological biochemical attributes. We highlight uptake metal controlled by cation exchange capacity, pH, size soil particles, root nature, other physio-chemical limitations. toxicity obstructs seed germination, root/shoot length, growth, final crop-yield. disrupts nutrient through roots, alters plasma membrane permeability, disturbs chloroplast ultrastructure triggers changes respiration as well transpiration activities, creates reactive oxygen species (ROS), activates some enzymatic non-enzymatic antioxidants. also impairs photosynthesis, water balance mineral nutrients, hormonal status, structure permeability. provides consolidated information concentrating current studies associated with Pb-induced oxidative stress conditions various plants, highlighting roles different antioxidants plants mitigating Pb-stress. Additionally, we discussed detoxification tolerance responses regulating gene expressions, protein, glutathione metabolisms resist phytotoxicity. Overall, approaches tackle have been addressed; phytoremediation techniques biochar amendments are economical eco-friendly remedies for improving Pb-contaminated soils.

Transcriptomics, proteomics, and metabolomics interventions prompt crop improvement against metal(loid) toxicity

Plant Cell Reports, Год журнала: 2024, Номер 43(3)

Опубликована: Фев. 27, 2024

The escalating challenges posed by metal(loid) toxicity in agricultural ecosystems, exacerbated rapid climate change and anthropogenic pressures, demand urgent attention. Soil contamination is a critical issue because it significantly impacts crop productivity. widespread threat of can jeopardize global food security due to contaminated supplies pose environmental risks, contributing soil water pollution thus impacting the whole ecosystem. In this context, plants have evolved complex mechanisms combat stress. Amid array innovative approaches, omics, notably transcriptomics, proteomics, metabolomics, emerged as transformative tools, shedding light on genes, proteins, key metabolites involved stress responses tolerance mechanisms. These identified candidates hold promise for developing high-yielding crops with desirable agronomic traits. Computational biology tools like bioinformatics, biological databases, analytical pipelines support these omics approaches harnessing diverse information facilitating mapping genotype-to-phenotype relationships under conditions. This review explores: (1) multifaceted strategies that use adapt their environment; (2) latest findings metal(loid)-mediated metabolomics studies across various plant species; (3) integration data artificial intelligence high-throughput phenotyping; (4) bioinformatics single and/or multi-omics integration; (5) insights into adaptations future outlooks; (6) capacity advances creating sustainable resilient thrive metal(loid)-contaminated environments.

Effects of Cadmium Pollution on Human Health: A Narrative Review

Atmosphere, Год журнала: 2025, Номер 16(2), С. 225 - 225

Опубликована: Фев. 17, 2025

Cadmium (Cd) is a pervasive environmental and industrial toxin that poses significant health risks. It readily moves through soil–plant systems, leading to global contamination human exposure diet, smoking, pollution. The main purpose of this review explore the effect Cd on physiological processes different bodies’ organs, including bones, kidneys, liver, as well immune, cerebrovascular, cardiovascular, reproductive systems. Accumulation in body can result poisoning with severe impacts bone kidney health, reduced mineral density due renal damage. Research has linked lung cancer pulmonary toxicity, elevated urinary biomarkers suggest compromised function. also affects immune systems; liver; contributing various diseases by disrupting blood pressure calcium regulation, causing oxidative stress DNA damage, impairing cell functions. Ongoing research essential fully understand Cd-induced toxicological effects develop effective interventions prevent mitigate

State-of-the-art OMICS strategies against toxic effects of heavy metals in plants: A review

Ecotoxicology and Environmental Safety, Год журнала: 2022, Номер 242, С. 113952 - 113952

Опубликована: Авг. 8, 2022

Environmental pollution of heavy metals (HMs), mainly due to anthropogenic activities, has received growing attention in recent decades. HMs, especially the non-essential carcinogenic ones, including chromium (Cr), cadmium (Cd), mercury (Hg), aluminum (Al), lead (Pb), and arsenic (As), have appeared as most significant air, water, soil pollutants, which adversely affect quantity, quality, security plant-based food all over world. Plants exposed HMs could experience decline growth yield. To avoid or tolerate toxic effects plants developed complicated defense mechanisms, absorption accumulation cell organelles, immobilization by forming complexes with organic chelates, extraction using numerous transporters, ion channels, signalling cascades, transcription elements, among others. OMICS strategies significantly understand mechanisms plant transcriptomics, genomics, proteomics, metabolomics, ionomics counter HM-mediated stress stimuli. These been considered be reliable feasible for investigating roles genomics (genomes), transcriptomic (coding), mRNA transcripts (non-coding), metabolomics (metabolites), (metal ions) enhance resistance tolerance plants. The developments mechanistic understandings HMs-plant interaction terms their absorption, translocation, toxicity invasions at molecular cellular levels, well plants' response adaptation against these stressors, are summarized present review. Transcriptomics, toxicities reviewed, while challenges future recommendations also discussed.

This research focused on the different approaches to transport and internal chelation of metals with amino acids organic in plants. Therefore, first phase, plants studied were identified characteristics bioaccumulation factors. Steria pumila, Echium angustifolium, Typha angustifolia, Sisymbrium austriacum as hyperaccumulators (Cd, Ni), accumulators (Pb, Sn, Se), excluders (Cr, Hg). On other hand, only showed characteristic accumulator for Cr. In second combined effects heavy tested by a multi-linear regression model.
