Due to anthropogenic activities, environmental pollution of heavy metals/metalloids (HMs) has increased and received growing attention in recent decades. Plants HM-contaminated soils have slower growth development, resulting lower agricultural yield. Exposure HMs leads the generation free radicals (oxidative stress), which alters plant morpho-physiological biochemical pathways at cellular tissue levels. evolved complex defense mechanisms avoid or tolerate toxic effects HMs, including absorption accumulation cell organelles, immobilization by forming complexes with organic chelates, extraction via numerous transporters, ion channels, signaling cascades, transcription elements, among others. Nonetheless, these internal defensive are insufficient overcome toxicity. Therefore, unveiling adaptation tolerance is necessary for sustainable agriculture. Recent breakthroughs cutting-edge approaches such as phytohormone gasotransmitters application, nanotechnology, omics, genetic engineering tools identified molecular regulators linked tolerance, may be applied generate HMs-tolerant future plants. This review summarizes systems that plants adapted resist toxicity, physiological, biochemical, responses. Diverse strategies also been comprehensively presented advance resilience toxicity could enable production.

Lead toxicity in Nicotiana tabacum L.: Damage antioxidant system and disturb plant metabolism

Ecotoxicology and Environmental Safety, Journal Year: 2025, Volume and Issue: 291, P. 117837 - 117837

In this study, we treated tobacco seedlings with 0, 200, 400, and 800 mg/kg Pb2 +, explored the response mechanism of under Pb stress through a combination growth physiology metabolomics analysis. The physiological results showed that compared CK, increase concentration, treatment inhibited growth, reduced biomass photosynthetic pigment content seedlings, severely damaged chloroplast structure. addition, pore conductivity density Pb800 decreased by 45.77 % 93.55 %, respectively. disrupted cell membrane system, increased malondialdehyde (MDA) in leaves roots 67.65 31.90 Meanwhile, activity SOD POD enzymes. Metabolomics enhanced tryptophan metabolism, glutathione alanine, aspartate, glutamate as well cysteine methionine metabolism pathways. These indicate increasing pigments hormones, clearing reactive oxygen species enhancing antioxidant enzyme activity, improving amino acid may play an important role reducing toxicity to tobacco.
