Cadmium (Cd) is a biologically non-essential heavy metal, major soil pollutant, and extremely harmful to plants. The phytohormone methyl jasmonate (MeJA) plays an important role in plant heavy-metal resistance. However, the understanding of effects MeJA supply level on alleviating Cd toxicity plants limited. Here, we investigated how regulated development physiological processes cell wall modification Cosmos bipinnatus. We found that low concentrations increased dry weight seedlings under 120 µM stress by reducing transport from roots shoots. Moreover, threshold concentration exogenous activities superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) roots, root wall, contents pectin hemicellulose 1 polysaccharides, through converting into pectin-bound forms. These results suggested mitigated modulating polysaccharide functional group composition, especially polysaccharides binding Cd, with capacity, specific chemical forms homeostatic antioxidant systems C.

Heavy metal pollution is one of the most devastating abiotic factors, significantly damaging crops and human health. One serious problems it causes a rise in cadmium (Cd) toxicity. Cd highly toxic with negative biological role, enters plants via soil–plant system. stress induces series disorders plants’ morphological, physiological, biochemical processes initiates inhibition seed germination, ultimately resulting reduced growth. Fiber such as kenaf, jute, hemp, cotton, flax have high industrial importance often face issue Various techniques been introduced to counter rising threats toxicity, including reducing content soil, mitigating effects stress, genetic improvements plant tolerance against this stress. For decades, breeders trying develop Cd-tolerant fiber through identification transformation novel genes. Still, complex mechanism has hindered progress breeding. These are ideal candidates for phytoremediation heavy metals contaminated soils. Hence, increased uptake, accumulation, translocation below-ground parts (roots) above-ground (shoots, leaves, stems) can help clean agricultural lands safe use food crops. Earlier studies indicated that detoxification, developing these stresses genes fruitful approaches. This review aims highlight role some conventional molecular key Molecular mainly involve QTL mapping GWAS. However, more focus given transcriptome TFs analysis explore potential genomic regions involved will serve source valuable information on crops, allowing further in-depth analyses identify critical breeding, like engineering CRISPR/Cas9.

Elicitors fortifies the plant resilience against metal and metalloid stress

International Journal of Phytoremediation, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 18

Published: Nov. 3, 2024

This review addresses plant interactions with HMs, emphasizing defence mechanisms and the role of chelating agents, antioxidants various elicitor molecules in mitigating metal toxicity plants. To combat soil contamination chelate assisted phytoextraction using application natural or synthetic aminopolycarboxylic acids is an effective strategy. Plants also employ diverse signaling pathways, including hormones, calcium, reactive oxygen species, nitric oxide, Mitogen-Activated Protein Kinases influencing gene expression to counter HM stress. Phytohormones enhance enzymatic non-enzymatic antioxidant mechanism level secondary metabolites plants when exposed Also it activates genes responsible for DNA repair mechanism. In addition, hormones can regulate activity several transporters thereby preventing their entry into cell. Elicitor metalloid absorption, sequestration transport Combining different elicitors like jasmonic acid, salicylic acid etc. effectively mitigates stress Moreover, microbes bacteria fungi, offer eco-friendly efficient solution remediation. Understanding these elicitors, pathways crucial developing strategies resilience
