Distinct Stress Regulators in the CRL Family: Emerging Roles of F‐Box Proteins

BioEssays, Journal Year: 2025, Volume and Issue: unknown

Published: March 16, 2025

ABSTRACT Cullin‐RING ligases (CRLs) are central regulators of environmental and cellular stress responses, orchestrating diverse processes through the ubiquitination substrate proteins. As modular complexes, CRLs employ substrate‐specific adaptors to target proteins for degradation other ubiquitin‐mediated processes, enabling dynamic adaptation cues. Recent advances have highlighted largest CRL subfamily SCF (Skp1‐cullin‐F‐box) in sensing, a role historically underappreciated ubiquitin ligases. Notably, emerging evidence suggests that F‐box domain, 50‐amino acid motif traditionally recognized mediating protein‐protein interactions, can act as direct sensor due its ability bind heavy metals. Despite these advances, roles many components sensing remain poorly understood. This review provides an overview response regulation emphasizes functions adaptation.

Phytotoxicity and Metals Mobility Assessment in Mining Wastes Amended with Various Biochars

Land, Journal Year: 2025, Volume and Issue: 14(2), P. 372 - 372

Published: Feb. 11, 2025

Mining activities often contaminate soils with heavy metals, generating environmental and health risks. This study investigates the ecotoxicity of muddy (Mw) sandy (Sw) mining wastes on Phaseolus vulgaris assesses impact five locally sourced biochar amendments plant growth soil pore water (SPW) properties. Most biochars improved retention, except for argan nut shells (An) biochar, highlighting importance feedstock type. Sw supported better than Mw regardless addition, due to textural differences. Palm fronds (Pf) significantly enhanced surface leaf area in Sw. SPW analysis revealed that affected pH electrical conductivity (EC) differently across types. consistently increased pH, while Sw’s was biochar-dependent. A significant 5.1-fold EC increase recorded amended Pf. All reduced Pb availability at planting, Cu decreased harvest. In Mw, Pb, Zn, Cu, uptake accumulation were unaffected by a slight reduction observed roots. germination test Lepidium sativum confirmed these findings, particularly inhibition An. dual approach highlights toxicity biochars’ potential as remediation programs.

Organic farming to mitigate biotic stresses under climate change scenario

Bulletin of the National Research Centre/Bulletin of the National Research Center, Journal Year: 2024, Volume and Issue: 48(1)

Published: July 16, 2024

Abstract Background Climate change is inevitable owing from modern-day chemical agriculture, exerting detrimental impacts on sustainable crop production. Global agriculture now facing serious threats biotic stresses like weeds, pests, diseases, etc. These not only hamper growth and production but also reduce quality. Main body of the abstract Exclusive reliance synthetic inputs to tackle has created resistance, resurgence, residues, etc., leading environmental pollution. Although plants adopt defensive mechansims, such need be addressed properly with various eco-friendly organic farming approaches. Suitable modification adoption agronomic practices (manual, mechanical, cultural, biological) as soil solarization, rotation, intercropping, tillage, sowing time method, nutrient, water intercultural operations, formulations, selection resistant/tolerant varieties, can mitigate negative a high extent resulting in uplift well quality produce. Microorganisms alter health positively for alleviate through bio-stimulant properties. Various indigenous technical knowledge approaches show great promise further. Short conclusion Adequate research, integration multiple technologies, build-up awareness, are keys successful plant protection under changing climate scenario.

The rapid growth of industrialization and urbanization in China has led to an increase soil heavy metal pollution, which poses a serious threat ecosystem safety human health. advancement spectral technology offers way rapidly non-destructively monitor content. In order explore the potential rice leaf spectra indirectly estimate We collected farmland samples measured Xushe Town, Yixing City, Jiangsu Province, China. laboratory, metals Cd As were determined. establish estimation model between pre-processed content, genetic algorithm (GA) was used optimise partial least squares regression (PLSR). model’s accuracy evaluated best obtained. results showed that pre-processing techniques can extract hidden information from spectra. first-order derivative absorbance more effective extracting sensitive GA-PLSR selects only about 10% bands better modeling than PLSR model. reflectance leaves capacity content (relative percent difference [RPD] = 2.09) good (RPD 2.97). Therefore, be estimated data leaves. This study provides reference for future remote sensing monitoring pollution is quantitative, dynamic, non-destructive over large area.

Total arsenic increased both root shoot treated with various concentrations increment was linear increasing arsenate. manifested via a decline inhibition phosphatase seedlings. acid alkaline phosphatases inhibited Similarly, inorganic pyrophosphatase ATPase also declined, along an concentration results suggest that exposure to leads lowering pool alteration major phosphohydrolytic enzymes, which contribute metabolic disturbance decrease growth During combined application exhibited better significant activities. Whereas altered level accumulation test seedlings, very little but high respect treatment alone thus inhibits transport external within However, when applied conjunction phosphate, improved changes enzymes. Notably, this levels, resulting lower roots higher shoots compared treatments alone. This suggests may inhibit thereby mitigating some negative impacts associated exposure.
