Abstract

Recent years have witnessed a gradual increase in the bioavailability and groundwater leaching of toxic heavy metals (HMs) in the environment, driven mainly by anthropogenic invasions. HMs, especially ranked as toxic/carcinogenic non-essential ones including Cadmium (Cd), Arsenic (As), Aluminium (Al), Mercury (Hg) and Lead (Pb) have emerged as the major soil, air and water contaminants affecting food production, quality and security worldwide. HMs affect plant growth and crop yield. Plants have developed intricate defense mechanisms for safeguarding themselves against the toxic effects imposed by HMs, including compartmentalization and sequestration in cell-organelles, inactivation by complex formation with the organic ligands and their exclusion using transporters, ion channels, transcription factors and signaling molecules, beside others. Omics approaches have generated significant resources and updates on the plant genome, transcriptome and metabolome plasticity against HM-induced stress stimuli. Omics technologies are pragmatic and seen as feasible approaches for characterizing the roles of genomes (genomics), coding (transcriptomics) and non-coding (miRNAomics) RNA transcripts, and metabolites (metabolomics) including metals (metallomics), which can ultimately be used for improving stress tolerance or generating resilience plant systems. This review aims to summarize the current understandings on the mechanistic insights of selected toxic (Cd, As, Al, Hg and Pb) HM-plant interactions, including their uptake, transport, toxicity and chelation/sequestration in cellular components, besides how plants respond and adapt to these stress factors. State-of-the-art in Omics approaches including genomics, transcriptomics, metabolomics, miRNAomics and metallomics for plant HM research have been presented. Present status, challenges and future prospects are also discussed.

  • The transport of HMs from roots to aerial parts involves active transporters found in the plasma membrane and vacuolar membrane, these transporters require energy, usually in form of ATP to concentrate metal ions into storage organelles, such as vacuoles.

    “Consequently, the transport of HMs from roots to aerial parts involves active transporters found in the plasma membrane and vacuolar membrane, these transporters require energy, usually in form of ATP to concentrate metal ions into storage organelles, such as vacuoles ( Figure 3 ).”

  • Inactive accumulation of metals occurs from the soil through roots and their transport through the xylem to the aerial parts of plants, such as stems, leaves, and other parts of shoots, by diverse classes of metal ion transporters.

    “In addition, inactive accumulation of metals occurs from the soil through roots and their transport through the xylem to the aerial parts of plants, such as stems, leaves, and other parts of shoots, by diverse classes of metal ion transporters (Feki et al., 2021; Jamla et al., 2021).”

    From Plant hyperaccumulators: a state-of-the-art review on mechanism of heavy metal transport and sequestration (2025) · cites this paper as Jamla et al., 2021

    Section 2, “Plant-heavy metal interactions” (page unavailable), describes root-to-shoot metal uptake involving transporters and movement through xylem to above-ground plant parts. It does not describe that process as “inactive accumulation”; its reference to passive adsorption concerns metals at the rhizosphere, not their accumulation in shoots. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
