Journal of Agricultural and Food Chemistry, Journal Year: 2024, Volume and Issue: 72(30), P. 16674 - 16686

Published: July 18, 2024

The potential impacts of biodegradable and nonbiodegradable microplastics (MPs) on rhizosphere microbial nitrogen (N) transformation processes remain ambiguous. Here, we systematically investigated how (polybutylene succinate, PBS) MPs (polyethylene, PE) affect N by determining soil indicators typical Glycine max (soybean)-soil (i.e., red brown soils) systems. Our results show that altered pH dissolved organic carbon in MP/soil type-dependent manners. Notably, soybean growth displayed greater sensitivity to 1% (w/w) PBS MP exposure than since acidified the impeded nutrient uptake plants. In rhizosphere, negatively impacted community composition diversity, weakened (mainly denitrification ammonification), disrupted metabolism. Overall, it is suggested MPs, compared can more significantly influence ecological function plant-soil system.

Interaction of ammonium nutrition with essential mineral cations

Journal of Experimental Botany, Journal Year: 2023, Volume and Issue: 74(19), P. 6131 - 6144

Published: June 3, 2023

Plant growth and development depend on sufficient nutrient availability in soils. Agricultural soils are generally nitrogen (N) deficient, thus need to be supplemented with fertilizers. Ammonium (NH4+) is a major inorganic N source. However, at high concentrations, NH4+ becomes stressor that inhibits plant growth. The cause of stress or toxicity multifactorial, but the interaction other nutrients among main determinants plants' sensitivity towards supply. In addition, uptake assimilation provoke acidification cell external medium (apoplast/rhizosphere), which has clear impact availability. This review summarizes current knowledge, both physiological molecular level, nutrition essential mineral elements absorbed as cations, macronutrients (K+, Ca2+, Mg2+) micronutrients (Fe2+/3+, Mn2+, Cu+/2+, Zn2+, Ni2+). We hypothesize considering these nutritional interactions, soil pH, when formulating fertilizers may key order boost use NH4+-based fertilizers, have less environmental compared nitrate-based ones. we convinced better understanding interactions will help identify novel targets potential improve crop productivity.

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.

Nitrogen (N) holds a prominent position in the metabolic system of plants, as it is main constituent amino acids, which are basic building blocks proteins and enzymes. Plants primarily absorb N form ammonium (NH4+) nitrate (NO3−). However, most plants exhibit severe toxicity symptoms when exposed to NH4+ sole source. Addressing stress requires effective strategies, use silicon (Si) has shown promising results. there lack underlying studies on impact C:N:P stoichiometric balance role Si these ratios. In this study, we explored effects varying concentrations (1, 7.5, 15, 22.5, 30 mmol L−1) stoichiometry yield beetroot hydroponic conditions. Additionally, investigated whether application (2 could mitigate detrimental caused by toxic levels. The experiment followed randomized block design based 5 × 2 factorial scheme with four replicates.
