Abstract:
... Biochar has been used to alleviate the contamination of antibiotic resistance genes (ARGs) in soil and to inhibit ARGs transfer from soil to plants. However, the effect of aged biochar on ARGs abundance in soil and ARGs enrichment in plants are scarcely investigated. In this study, a pot experiment was conducted to compare the effects of fresh and aged biochars on the accumulation of five typical ...

Abstract:
... Phosphate, as an important non-renewable agricultural resource, needs to be recovered from wastewater at mg/L scale. Calcite carbonate fine powder was used in P-recovery but could only work in recovering high concentration phosphate. Herein, a new strategy is explored using in situ-formed CaCO₃ microspheres (CaCO₃-in situ) to realize efficient and fast P-recovery by adding CaCl₂ and Na₂CO₃ solutio ...

Abstract:
... Sludge-derived biochar (BS) was prepared by pyrolyzing municipal sludge at different temperatures and was used to recover NH₄⁺–N and PO₄³⁻–P from urine. The effects of dosage, adsorption time, and urine concentration on the adsorption of NH₄⁺–N and PO₄³⁻–P were investigated, and the adsorbed BS was used as a fertilizer to study its effect on the growth of pakchoi cabbage. The Elovich model was mor ...

Abstract:
... Nowadays, remediation of soil contaminated with potentially toxic metal is a great international concern. In this study, a novel modified gangue material (MGE) is synthesized from coal gangue (GE) through a low-temperature assisted with alkali roasting method, and is applied to the immobilization of cadmium (Cd²⁺) in contaminated soil. The various instruments (SEM-EDS, FTIR, XRD, TGA, and XPS) are ...

Abstract:
... Plants synthesize phytochelatins to chelate in vivo toxic heavy metal ions and produce nontoxic complexes for tolerating the stress. Detection of the complexes would simplify the identification of high phytoremediation cultivars, as well as assessment of plant food for safe consumption. Thus, a confocal Raman spectroscopy combined with density functional theory and deep learning was used for chara ...
... Human intake of selenium (Se) mainly occurs through the food chain, and is largely dependent on the bioavailability of soil Se. Sulfur (S) and phosphorus (P) also as essential nutrients for plants, their antagonistic with Se effects on Se bioavailability should be considered. We conducted pot experiments to investigate the interaction effect on the bioavailability of Se in the soil using a sequent ...
... Vegetable production systems are hotspots of nitrous oxide (N₂O) emissions and antibiotic pollution. However, little is known about the interconnections among N₂O emissions, vegetable growth, and antibiotic contamination. To understand how plants regulate N₂O emissions from enrofloxacin (ENR)-contaminated soils, in situ N₂O emissions were measured in pot experiments with cherry radish and pakchoi. ...

Abstract:
... The prevalence of bacterial resistance caused by the application of animal manure has become an important environmental issue. Herein, the vertical migration of antibiotic resistance genes (ARGs) and pathogens in soil and vegetables after the application of different fertilizers was explored. The results showed that the application of composted manure considerably enhanced the abundance of most AR ...

Abstract:
... Pakchoi (Brassica rapa L. Chinensis) is an important vegetable in Asia. Pseudomonas palleroniana is one of the specific spoilage organisms (SSOs) of fresh-cut pakchoi. The purpose of this study was to investigate changes to the endogenous metabolic spectrum of violet light (405 nm) with regard to food spoilage bacteria from fresh-cut pakchoi using ultrahigh-performance liquid chromatography-tandem ...

Abstract:
... Blue light can improve the nutritional value of vegetables grown in greenhouse, while the mechanisms about the biosynthesis and accumulation of glucosinolates regulated by light signaling still unknown. Here, the soluble amino acid and glucosinolate profiles under supplementary different blue light intensities (T50, T100, T150) for 10 days were investigated in green-leaf and red-leaf pakchoi. The ...
... Zinc oxide nanoparticles (ZnO NPs) widely used have caught the attention of researchers, nevertheless, phytotoxicity, bioaccumulation, and potential risks thereof to the green leafy still have knowledge defects. A pot experiment was intended to cultivate pakchoi (Brassica chinensis L.) following root exposure to ZnO NPs and Zn²⁺. ZnO NPs promoted plant growth and Zn accumulation, formed a dose-dep ...

Abstract:
... The rapid development of greenhouse vegetable production (GVP) in densely populated areas may cause the heavy metal/metalloid accumulation in soil and pose a threat to human health. In this study, 180 pairs of topsoil and pak choi (Brassica chinensis L.) samples were collected from GVP fields in Xi’an city in Northwest China to analyze health risks of Cd, Cr, Pb, and As in soil and pak choi combin ...

Abstract:
... Cadmium (Cd) immobilization in the cell wall is responsible for Cd detoxification in Cd-accumulating cultivars. Lignin is the dominant constituent of the secondary cell wall (SCW), but its role in Cd compartmentalization is poorly understood. The mechanism of Cd compartmentalization by lignin was thus investigated herein. Lignin content and composition, as well as related genes and proteins, were ...

Abstract:
... Nitrate accumulation is one of the main factors of secondary soil salinization in protected horticulture in China. Previous studies have shown that a low red(R)/far-red (FR) ratio can improve the salt tolerance of plants under NaCl stress. However, the effect of a low R/FR ratio on plant growth under nitrate stress is not clear. In order to explore the effect of a low R/FR ratio on the adaptabilit ...

Abstract:
... Lead (Pb) poses an adverse effect on plant growth and development. Glycinebetaine (GB) plays an important role in plants response to stress environment. The study was performed to examine the potential of exogenous GB (0.5, 1, 2, and 5 mM) in alleviating Pb toxicity, the physiological and biochemical responses in pakchoi under 100 μM Pb stress by hydroponic experiment. Pb stress significantly decr ...
... Selenium (Se) can be used to counteract cadmium (Cd) toxicity in plants. However, mechanisms underlying the alleviation of Cd toxicity by Se have not been completely elucidated, especially those by which Se reduces Cd translocation. A hydroponic experiment was performed to illustrate the regulatory mechanisms of Cd transport by selenate (Se (VI)) in pakchoi (Brassica rapa L., LvYou 102). The resul ...
