Traditional farming practices are increasingly being replaced with more sustainable approaches, including the development of slow-release fertilizers (SRFs), to mitigate environmental stress and ensure food security for ever-growing global population. Despite rising focus on eco-friendly materials like biopolymers fertilizer coatings, optimizing their hydrophobicity remains a significant challenge. In this context, nanotechnology offers promising route toward achieving sustainability. study, hydrophobic colloidal lignin particles (20–50 nm) were synthesized using straightforward acid precipitation method involving coprecipitation (LGe) sodium dodecyl sulfate (SDS). This strategy aimed reduce particle size, enhance stability, increase by incorporating nonpolar SDS alkyl chains onto surface nanomicelles. TEM STEM microscopy confirmed formation core–shell hybrid micelles, which incorporated into cross-linked carboxymethyl cellulose (CMC) matrix at various ratios produce series waterborne coating formulations films. The spherical morphology new features, along integration an interpenetrating network, led nanostructured films good (WCA ∼ 106.1°) slow biodegradability in soil. When applied diammonium phosphate (DAP) granular fertilizer, coatings revealed interfacial adhesion, enhanced hardness (2.5-fold), improved water-holding capacity soil (18%). Most importantly, 100 day nutrient leaching study impressive nutrient-release longevity, showing 75% reduction N–P leaching. Subsequently, these SRFs evaluated 6 month wheat (Triticum aestivum)) cultivation trial across different textures, demonstrating substantial enhancements leaf area (150–200%), total root length (160%), biomass production (575%), grain yield (115–264%), quality-related parameters. These findings highlight robust solution addressing deficiencies promoting agricultural practices, especially crops extended growth cycles, while inspiring novel broader applications.

Jasmonate signaling modulates root growth by suppressing iron accumulation during ammonium stress

PLANT PHYSIOLOGY, Journal Year: 2024, Volume and Issue: unknown

Published: July 24, 2024

Abstract Plants adapt to changing environmental conditions by adjusting their growth physiology. Nitrate (NO3−) and ammonium (NH4+) are the major inorganic nitrogen forms for plant uptake. However, high NH4+ inhibits growth, roots undergo striking changes, such as inhibition of cell expansion division, leading reduced root elongation. In this work, we show that modulates metabolism developmental physiology inhibiting iron (Fe)-dependent Jasmonate (JA) signaling response in Arabidopsis (Arabidopsis thaliana). Transcriptomic data suggested availability regulates Fe JA-responsive genes. High levels led enhanced accumulation, which impaired balance suppressing JA biosynthesis response. Integrating pharmacological, physiological, genetic experiments revealed involvement Fe-derived responses regulating through modulation pathway during stress. The transcription factor MYC2 directly bound promoter NITRATE TRANSPORTER 1.1 (NRT1.1) repressed it optimize NH4+/Fe-JA adaptation Our findings illustrate intricate between nutrient hormone-derived pathways appear essential optimizing physiological metabolic NH4+/Fe

Phenotype Assessment and Putative Mechanisms of Ammonium Toxicity to Plants

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(6), P. 2606 - 2606

Published: March 13, 2025

Ammonium (NH4+) and nitrate (NO3−) are the primary inorganic nitrogen (N) sources that exert influence on plant growth development. Nevertheless, when NH4+ constitutes sole or dominant N source, it can inhibit growth, a process also known as ammonium toxicity. Over multiple decades, researchers have shown increasing interest in causes, mechanisms, detoxification strategies of Despite this progress, current investigations into mechanisms toxicity remain equivocal. This review initially presents comprehensive assessment phenotypes induced by Additionally, recapitulates existing toxicity, such ion imbalance, disruption phytohormones homeostasis, ROS (reactive oxygen species) burst, energy expenditure, rhizosphere acidification. We conclude alterations carbon–nitrogen (C-N) metabolism high may be one main reasons for SnRK1 (Sucrose non-fermenting 1-related kinase) might involved process. The insights proffered will facilitate exploration tolerance development NH4+-tolerant crops agricultural industries.
