Manganese (Mn) is among one of the essential trace elements for normal plant development; however, excessive Mn can cause growth and development to be hindered. Nevertheless, regulatory mechanisms root response poisoning remain unclear. In present study, results revealed that was inhibited when exposed poisoning. Physiological showed antioxidase enzyme activities (peroxidase, superoxide dismutase, ascorbate peroxidase, catalase) proline, malondialdehyde, soluble sugar contents increased significantly under toxicity stress (100 μM Mn), whereas protein four hormones’ (indolebutyric acid, abscisic indoleacetic gibberellic acid 3) decreased significantly. addition, Mn, Fe, Na, Al, Se in roots significantly, those Mg, Zn, K Furthermore, RNA sequencing (RNA-seq) analysis used test differentially expressed genes (DEGs) soybean The found 45,274 1430 DEGs concentrations 5 (normal) 100 (toxicity) μM. Among these DEGs, 572 were upregulated 858 downregulated, indicating may initiate complex molecular on stress. quantitative RT-PCR indicated many or downregulated markedly roots, suggesting regulation complex. Therefore, mechanism complicated. Present lay foundation further study function involved regulating tolerance traits roots.

Biochar for the Mitigation of Metal/Metalloid Stress in Plants

Journal of Plant Growth Regulation, Journal Year: 2024, Volume and Issue: 43(10), P. 3303 - 3319

Published: May 8, 2024

Abstract Metal(loid) pollution has become one of the most pressing environmental issues, threatening all living organisms. stress adversely impacts plant growth, physiology, and overall productivity. Numerous physicochemical approaches have been developed employed to counteract reduce detrimental effects metal(loid)s. However, these methods raised concerns, leading questions about their appropriateness efficacy. Consequently, alternative eco-friendly solutions, such as application biochar, gained prominence. Biochar is a carbon-rich material derived from pyrolysis hydrothermal processes various organic materials. Due its exceptional properties, biochar believed enhance soil quality fertility. Several global studies underscored positive role in reducing uptake metal(loid)s by plants polluted soils. In this article, we explore facets reactions toxicity attempt draw links between use improvements physiology performance. We also review effectiveness phytoremediation, influence on nutrient adsorption mechanisms, assisting growth defense systems.

Regulatory Mechanism through Which Old Soybean Leaves Respond to Mn Toxicity Stress

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(10), P. 5341 - 5341

Published: May 14, 2024

Manganese (Mn) is a heavy metal that can cause excessive Mn poisoning in plants, disrupting microstructural homeostasis and impairing growth development. However, the specific response mechanisms of leaves to have not been fully elucidated. This study revealed soybean plants resulted yellowing old leaves. Physiological assessments these significant increases antioxidant enzymes activities (peroxidase (POD), superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT)) elevated levels malondialdehyde (MDA), proline, indoleacetic acid (IAA), salicylic (SA), under 100 μM toxicity. Conversely, abscisic (ABA), gibberellin 3 (GA3), jasmonic (JA) significantly decreased. The content affected increased, while Ca, Na, K, Cu Transcriptome analysis 2258 differentially expressed genes Mn-stressed leaves, 744 which were upregulated 1514 downregulated; included associated with ion transporters, hormone synthesis, various enzymes. Quantitative RT-PCR (qRT-PCR) verification fifteen confirmed altered gene expression These findings suggest complex regulatory mechanism toxicity stress, providing foundation for further exploration tolerance-related Using methods described above, this will investigate molecular leaves' poisoning, identify key play roles lay groundwork cultivating high-quality varieties tolerance traits.

Biochar and sulfur are considered useful amendments for soil cadmium (Cd) contamination remediation. However, there is still a gap in the understanding of how combined biochar application affects Cd resistance rice, role accumulation iron plaque expression efflux transporter-related genes unclear this type treatment. In study, we screened an effective combination (0.75 % biochar, 60 mg/kg sulfur) that significantly reduced content rice roots (32.9 %) shoots (12.3 %); amino acids their derivatives, organic derivatives flavonoids roots; altered secondary metabolite production release. This alleviated toxicity to which enhancement (24.8 formation upregulated heavy metal effector (NRAMP3, MTP3, ZIP1) were important factors. These findings show transport involved detoxification under sulfur, provides information treatment pollution.
