Constructing Lewis Acid-Base Pairs to Boost Electrocatalytic Hydrogenation of p-Nitrobenzoic Acid to Valuable p-Aminobenzoic Acid Using Water as the Hydrogen Source.

Electrocatalytic hydrogenation of toxic nitrobenzene to value-added aniline is of great significance in addressing the issues of energy crisis and environmental pollution. However, it is a considerable challenging and crucial to develop highly efficient and earth-abundant transition metal-based electrocatalysts with superior durability for the electro-hydrogenation of nitrobenzene due to the competitive hydrogen evolution reaction (HER). In this work, a facile approach is designed and introduced to constructing an integrated self-supported heterostructured Co Ni(OH)(CO)/Al(OH) nanoarrays (CoNiCH/Al(OH)) for the electrocatalytic reduction of nitrobenzoic acid (PNBA) to p-aminobenzoic acid (PABA) and its electrocatalytic mechanism for PNBA reduction is investigated.

Biological Characteristics of a Novel Bibenzyl Synthase () Gene from Catalyzing Dihydroresveratrol Synthesis.

Bibenzyl compounds are one of the most important bioactive components of natural medicine. However, as a traditional herbal medicine is rich in bibenzyl compounds and performs functions such as acting as an antioxidant, inhibiting cancer cell growth, and assisting in neuro-protection. The biosynthesis of bibenzyl products is regulated by bibenzyl synthase (BBS).

Waterlogging in soil restricts the growth of seedlings and inhibits the accumulation of lignans and phenolic acids in thorns.

, commonly known as Chinese Zaojiao, has important economic value and medicinal compounds in its fruits and thorns, making it widely cultivated artificially in China. However, the available literature on the impact of waterlogging on the growth of seedlings and the accumulation of metabolite compounds in its thorns is limited. To address this knowledge gap, seedlings were planted in soil supplemented with pindstrup substrate, which enhances the water-holding capacity of the soil.

Assessing inter-intraspecific variability of leaf vulnerability to embolism for 10 alpine Rhododendron species growing in Southwestern China.

Alpine Rhododendron species are prominent constituents and renowned ornamental plants in alpine ecosystems. Consequently, evaluating the genetic variation in embolism resistance within the genus Rhododendron and predicting their adaptability to future climate change is important. Nevertheless, the assessment of embolism resistance in Rhododendron species remains limited.

Early and Late Transcriptomic and Metabolomic Responses of 'Xiaotaohong' Petals to Infection with sp.

In recent years, petal blight disease caused by pathogens has become increasingly epidemic in . Breeding disease-resistant rhododendron is considered to be a more environmentally friendly strategy than is the use of chemical reagents. In this study, we aimed to investigate the response mechanisms of rhododendron varieties to petal blight, using transcriptomics and metabolomics analyses.

Transcriptomic, Physiological, and Metabolomic Response of an Alpine Plant, , to Waterlogging Stress and Post-Waterlogging Recovery.

Climate change has resulted in frequent heavy and prolonged rainfall events that exacerbate waterlogging stress, leading to the death of certain alpine trees. To shed light on the physiological and molecular mechanisms behind waterlogging stress in woody trees, we conducted a study of , a well-known alpine flower species. Specifically, we investigated the physiological and molecular changes that occurred in leaves of subjected to 30 days of waterlogging stress (WS30d), as well as subsequent post-waterlogging recovery period of 10 days (WS30d-R10d).

Untargeted metabolite profiling of petal blight in field-grown Rhododendron agastum using GC-TOF-MS and UHPLC-QTOF-MS/MS.

Petal blight caused by fungi is among the most destructive diseases of Rhododendron, especially Rhododendron agastum. Nonetheless, the metabolite changes that occur during petal blight are unknown. We used untargeted gas chromatography time-of-flight mass spectrometry (GC-TOF-MS) and ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) to compare the metabolite profiles of healthy and petal blight R.

Exotic Spartina alterniflora invasion increases CH while reduces CO emissions from mangrove wetland soils in southeastern China.

Mangroves are critical in global carbon budget while vulnerable to exotic plant invasion. Spartina alterniflora, one of typical salt marsh plant grows forcefully along the coast of China, has invaded the native mangrove habitats in Zhangjiang Estuary. However, the effects of S.

Elevated nitrogen metabolism and nitric oxide production are involved in Arabidopsis resistance to acid rain.

Acid rain (AR) can induce great damages to plants and could be classified into different types according to the different SO/NO ratio. However, the mechanism of plants' responding to different types of AR has not been elucidated clearly. Here, we found that nitric-rich simulated AR (N-SiAR) induced less leaves injury as lower necrosis percentage, better physiological parameters and reduced oxidative damage in the leaves of N-SiAR treated Arabidopsis thaliana compared with sulfate and nitrate mixed (SN-SiAR) or sulfuric-rich (S-SiAR) simulated AR treated ones.

[Network pharmacology-based study on mechanism of Yuanhu Zhitong Dropping Pills in the treatment of primary dysmenorrhea].

This study was designed to explore the mechanism of Yuanhu Zhitong Dropping Pills(YHZT) in the treatment of primary dysmenorrhea by pharmacological network technology and establish a research approach of "Compound-Target-Pathway-Disease" network. Twenty-eight compounds absorbed into blood including 22 prototype and 6 metabolites of YHZT were submitted to Pharm Mapper and Kyoto Encyclopedia of Genes and Genomes(KEGG) bioinformatics softwares to predict the target proteins and related pathways respectively. The network of "Compound-Target-Pathway-Disease" was constructed and analyzed using Cytoscape software.
