Improving nitrogen-use efficiency is an important path toward enhancing crop yield and alleviating the environmental impacts of fertilizer use. Ammonium (NH4+) energetically preferred inorganic N source for plants. The interaction NH4+ with other nutrients a chief determinant ammonium-use (AUE) tipping point ammonium toxicity, but these interactions have remained ill-defined. Here, we report that iron (Fe) accumulation critical factor determining AUE identified substance can enhance by manipulating Fe availability. under nutrition induces efflux in root system, reducing both growth Arabidopsis (Arabidopsis thaliana). Low external availability low plant status substantially protein N-glycosylation through Vitamin C1-independent pathway, thereby to increase during vegetative stage elevated supply. We confirm validity iron-ammonium species lettuce (Lactuca sativa). further show dolomite act as effective substrate subdue expression Phosphate Root 2 acidification rhizosphere. Our findings present strategy improve reveal underlying molecular-physiological mechanism.

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.

Manganese and phosphorus maize shoot concentrations are differently affected by nitrification inhibitor‐driven rhizosphere acidification

Soil Use and Management, Journal Year: 2024, Volume and Issue: 40(2)

Published: April 1, 2024

Abstract High soil pH can lead to Mn 2+ and P deficiency yield losses. In addition, it is unclear which process, nitrification‐induced acidification of bulk or nitrification inhibitor‐driven rhizosphere acidification, more effective in increasing availability shoot concentration. Thus, this topic was investigated study. Moreover, we also evaluated if applying NIs avoid with high buffering capacity. Two greenhouse experiments were carried out investigate the impact 3,4‐Dimethylpyrazole phosphate (DMPP) sandy subjected application different lime rates, simulating several capacity conditions. The utilized rates 0, 0.5, 1, 2 4 g CaCO 3 kg −1 . measured variables pH, availability, maize biomass production, as well concentrations. DMPP significantly reduced by 10% unlimed soil; however, promoted overall 30% limed both experiments. decreased concentration 24 21% I II, respectively. contrast, increased due 17% did not under highest rate (4 ) despite alleviating it. conclusion, beneficial for and, when performed increase soils, should consider likelihood causing deficiency.

Root phosphoenolpyruvate carboxylase activity is essential for Sorghum bicolor tolerance to ammonium nutrition

Plant Physiology and Biochemistry, Journal Year: 2023, Volume and Issue: 206, P. 108312 - 108312

Published: Dec. 25, 2023

Phosphoenolpyruvate carboxylase (PEPC; EC 4.1.1.31) is an enzyme family with pivotal roles in plant carbon and nitrogen metabolisms. A main role for non-photosynthetic PEPC as anaplerotic to load tricarboxylic acid (TCA) cycle skeletons that compensate the intermediates diverted biomolecule synthesis such amino acids. When plants are grown under ammonium (NH4+) nutrition, excessive uptake of NH4+ often provokes a stress situation. face stress, N assimilation greatly induced thus, requires supply coming from TCA cycle. In this work, we addressed importance root sorghum (Sorghum bicolor L. Moench), C4 cereal crop, nutrition. To do so, used RNAi lines display decrease expression SbPPC3 (Ppc3 lines), isoform, reduced activity. silencing provoked hypersensitivity, meaning lower biomass accumulation Ppc3 respect WT when growing The silenced presented deregulation primary metabolism highlighted by alteration normal functioning, which was evidenced organic acids Altogether, our work evidences PEPC, cycle, deal high external availability.
