Abstract
Mineral nutrients spatiotemporally participate in the biosynthesis and accumulation of storage biopolymers, which directly determines the harvested grain yield and quality. Optimizing fertilizer nutrient availability improves the grain yield, but quality aspects are often underestimated. We hypothesize that extensive mineral nutrients have significant effects on the biosynthesis, content, and composition of storage proteins, ultimately determining physicochemical properties and food quality, particularly in the context of climate change. To investigate this, we hierarchized 16 plant mineral nutrients and developed a novel climate-nutrient-crop model to address the fundamental question of the roles of protein and starch in grain-based food quality. Finally, we recommend increasing the added value of mineral nutrients as a socioeconomic strategy to enhance agro-food profitability, promote environmental sustainability, and improve climate resilience.

Abstract
Onions (Allium cepa L.) are considered a salt-sensitive crop. However, to date, little evidence supports this claim and information about the physiological and metabolomic effects of Na+ accumulation in onion plants is lacking. The purpose of our research has been to assess changes in onion bulbs of three different cultivars after soil and foliar applications with moderate doses of chloride-free Na2SO4. The antioxidative defense mechanism in onion and the accumulation of Na+ within the plant has also been analyzed. Based on Na+ leaf and bulb concentrations, our findings demonstrate that Na+ is only transported from bulbs to leaves not vice versa, therefore foliar application does not lead to Na+ accumulation in the bulbs. Soil application with Na2SO4 results in an accumulation of Na+ in the leaves and bulbs, but with the exception of one onion variety this accumulation does not alter the metabolite profile of onions significantly. Even the K+ concentration and organic solute levels are unchanged after accumulation of Na+. Nevertheless, after Na2SO4 treatment, the antioxidative defense system moderately increases in onion bulbs. This study demonstrates that onion plants have the ability to exclude Na+ at moderate Na2SO4 treatment, and that the potential for quality onion production in soils with increased sodium concentration is much higher than previously assumed.

Abstract
Stomatal movements are enabled by changes in guard cell turgor facilitated via transient accumulation of inorganic and organic ions imported from the apoplast or biosynthesized within guard cells. Under salinity, excess salt ions accumulate within plant tissues resulting in osmotic and ionic stress. To elucidate whether (a) Na+ and Cl- concentrations increase in guard cells in response to long-term NaCl exposure and how (b) guard cell metabolism acclimates to the anticipated stress, we profiled the ions and primary metabolites of leaves, the apoplast and isolated guard cells at darkness and during light, that is, closed and fully opened stomata. In contrast to leaves, the primary metabolism of guard cell preparations remained predominantly unaffected by increased salt ion concentrations. Orchestrated reductions of stomatal aperture and guard cell osmolyte synthesis were found, but unlike in leaves, no increases of stress responsive metabolites or compatible solutes occurred. Diverging regulation of guard cell metabolism might be a prerequisite to facilitate the constant adjustment of turgor that affects aperture. Moreover, the photoperiod-dependent sucrose accumulation in the apoplast and guard cells changed to a permanently replete condition under NaCl, indicating that stress-related photosynthate accumulation in leaves contributes to the permanent closing response of stomata under stress.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2020; 746:141244.

Abstract
Global climate change has exacerbated flooding in coastal areas affected by soil salinization. Ammonium (NH4+) is the predominant form of nitrogen in flooded soils, but the role played by NH4+ in the plant response to salt stress has not been fully clarified. We investigated the responses of Arabidopsis thaliana, Oryza sativa, and Nicotiana benthamiana plants fed with NH4+. All species were hypersensitive to NaCl stress and accumulated more Cl- and less Na+ than those fed with NO3-. Further investigation of A. thaliana indicated that salt hypersensitivity induced by the presence of NH4+ was abolished by removing the Cl- but was not affected by the removal of Na+, suggesting that excess accumulation of Cl- rather than Na+ is involved in NH4+-conferred salt hypersensitivity. The expression of nitrate transporter NRT1.1 protein was also up-regulated by NH4+ treatment, which increased root Cl- uptake due to the Cl- uptake activity of NRT1.1 and the absence of uptake competition from NO3-. Knockout of NRT1.1 in plants decreased their root Cl- uptake and retracted the NH4+-conferred salt hypersensitivity. Our findings revealed that NH4+-aggravated salt stress in plants is associated with Cl- over-accumulation through the up-regulation of NRT1.1-mediated Cl- uptake. These findings suggest the significant impact of Cl- toxicity in flooded coastal areas, an issue of ecological significance.

Abstract
This study systematically investigated the phytotoxicity of chicken manure co-composted with tobacco powder and mushroom substrate on seed germination during active phase of composting. All compost products met the sanitation requirements specified in the Chinese national standard; however, only the mushroom substrate compost satisfied the maturity standard. From day 28, the composting entered the end of active phase and the concentrations of K+, Zn2+, Na+, Cu2+ and Fe3+ decreased gradually. Redundancy analysis indicated that the germination index, catalase and peroxidase activities was positively correlated with K+, Zn2+, Na+, Cu2+, Fe3+ and NO3--N, and negatively correlated with NH4+-N, Mg2+ and Ca2+, among which the most significant ions were Fe3+, Mg2+ and Zn2+ for all treatments. The malondialdehyde concentration of germinated seeds had adverse correlation with the above ions parameters.

Abstract
The study investigates the effect of cadmium (Cd), salinity (NaCl), and combined stress on rhizosphere pH, growth parameters, membrane leakage, and genotoxicity in Vicia faba. Germinated seeds were exposed for 48 h to 0.01 mM Cd(NO3)2 (Cd), 50 mM NaCl (S50), 150 mM NaCl (S150), and Cd-NaCl (CdS50 and CdS150). An accumulation of Cd and Na was found essentially in Vicia roots under each single stress factor associated with variations in rhizosphere pH. Additional NaCl in metallic solution significantly dropped the rhizosphere pH and decreased Cd concentrations in roots by 2.3 and 3.8 times for CdS50 and CdS150, respectively. Growth parameters (root length and fresh and dry matters), mitotic activity, and micronucleus formation were not influenced by Cd and low concentration of NaCl when applied separately or together, while 150 mM of NaCl, alone or combined with Cd, affected negatively all the studied parameters, as well as chromosome and nucleus stability. V. faba seems to reduce the transport of Cd in saline conditions and therefore salinity (50 mM) may act as a protection against Cd accumulation.
