Article Abstract
In this study, effect of nitrate-dependent suberization in maize root on cadmium (Cd) uptake and accumulation was investigated. Suberization in maize roots was significantly lower in plants grown with a high nitrate supply compared with low nitrate. This decrease was seen in the total amount of suberin, in which the aliphatic suberin amount was significantly decreased, whereas no difference in aromatic suberin content between different N-treatments. RNA-sequencing showed that suberin biosynthesis genes were upregulated in low nitrate treatment, which correlated well with the increased suberin content. Bioimaging and xylem sap analysis showed that reduced exodermal and endodermal suberization in roots of plants grown under high nitrate promoted radial Cd transport along the crown root. The enhanced suberization in crown roots of plants grown in low nitrate restricted the radial transport of Cd from epidermis to cortex via decreased accessibility to Cd related transporters at the plasmalemma. Also, under low nitrate supply, the Cd transport gene ZmNramp5 was upregulated in the crown root, which may enhance Cd uptake by root tip where exodermis and endodermis were not fully suberized. These results suggest that high nitrate supply enhances Cd uptake and radial transport in maize roots by reducing exodermal and endodermal suberization.

Objectives: Antibiotic resistance towards penicillin has been attempted to counter by chemically modifying ampicillin through the conjugation with silver nanoparticles (AgNPs). The current study optimizes the conditions for synthesizing and characterizing AgNP-ampicillin to quantify the conjugation extent, evaluate the antibacterial efficacy, and explore the underlying antibacterial mechanisms.
Materials And Methods: AgNPs were synthesized from silver nitrate by chemical reduction method, silica-coated with tetraethyl orthosilicate (TEOS) and amine functionalized by (3-aminopropyl) triethoxysilane (APTES), which was then conjugated with ampicillin via the carbodiimide chemistry.

The accumulation of nitrate (NO) from agricultural runoff poses a growing threat to ecosystems and public health. Converting nitrate into ammonia (NH) through the electrochemical nitrate reduction reaction (NORR) offers a promising strategy to mitigate environmental contamination while creating a sustainable circular route to fertilizer production. However, achieving high NH production and energy efficiency remains challenging.

In this study, copper-modified nanocarbon composites (OMC) were successfully prepared using two-dimensional carbon nanosheets as the material substrate, the low-temperature hydrothermal method as the main process, and copper nitrate as the modifier. The effects of the modifier dosage ratio, hydrothermal temperature, and residence time on the structure and hydrogen sulfide (HS) adsorption performance of OMC were investigated. The results show that the OMC with persistent free radicals and copper oxides prepared under the conditions of a mass ratio of copper nitrate to two-dimensional carbon nanosheets of 2, a hydrothermal temperature of 130 °C, and a time of 8 h, respectively, has the best adsorption performance for HS, with an adsorption sulfur capacity of up to 46.
