Metabolomic Effects of CeO₂, SiO₂ and CuO Metal Oxide Nanomaterials on HepG2 Cells [PDF]

open access: yes, 2017
Background: To better assess potential hepatotoxicity of nanomaterials, human liver HepG2 cells were exposed for 3 days to five different CeO2 (either 30 or 100 μg/ml), 3 SiO2 based (30 μg/ml) or 1 CuO (3 μg/ml) nanomaterials with dry primary particle ...

Calcium and Nitrogen Availability Controls Root Exudation in Hydroponically Cultured Barley

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Root exudation is a key component of plant‐rhizosphere interactome. It is increasingly evident that root exudates influence rhizospheric microbial communities and in turn can benefit plants through improved resource allocation. However, how suboptimal nutrient availability relates to control of root exudation is poorly understood.

Root Structural and Metabolic Plasticity Confers Tolerance to Salinity in Wild Barley Species Grown Under Waterlogging

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Salinity combined with waterlogging is a major abiotic stress that severely limits crop growth and yield. We investigated species‐specific adaptations to salinity under constant waterlogging conditions in the wild halophytic barleys Hordeum marinum and H. glaucum, compared with the cultivated H. vulgare.

Highly heterozygous Citrus changshan‐huyou Y. B. Chang originated from ancient hybridization between mandarin and pummelo and displayed distinct tissue‐specific allelic imbalance

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract The genus Citrus is characterized by a reticulate evolutionary history with frequent hybridization, making it an intriguing subject for genome evolution investigation. Citrus changshan‐huyou Y. B. Chang (Huyou) is a unique landrace first discovered in Zhejiang Province, China, with premium fruit quality.

The Extract of Rosa roxburghii Tratt Alleviates Pulmonary Fibrosis in Mice via Gut Microbiota‐Amino Acid Metabolism and JAK2/STAT3 Inhibition

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
The ethyl acetate extract of Rosa roxburghii Tratt (EAE) alleviated pulmonary fibrosis through modulation of gut microbiota‐amino acid metabolism and inhibition of the JAK2/STAT3 signaling pathway. Bioactive components and antioxidant capacity were evaluated across different polar extracts of Rosa roxburghii Tratt (RRTEs). The EAE exhibited the highest

Novel GH115 xylan α‐1,2‐glucuronidases with distinct preferences for xylan‐derived oligomers and polymers

open access: yesProtein Science, Volume 35, Issue 5, May 2026.
Abstract Natural polymers are promising sustainable materials for diverse applications. Xylans, major components of hemicellulose, exhibit origin‐dependent substitution patterns that determine their physicochemical properties. Targeted enzymatic modification of these substituents offers a mild and precise approach for tailoring the polymer's ...

Beneficial rhizobacteria and virus infection modulate the soybean metabolome and influence the feeding preferences of the virus vector Epilachna varivestis

open access: yesNew Phytologist, Volume 250, Issue 4, Page 2599-2618, May 2026.
Summary Beneficial rhizobacteria and viral pathogens can both alter host plant phenotypes, yet little is known about how their simultaneous presence influences plant metabolism and species interactions. We investigated how two rhizobacteria, Bradyrhizobium japonicum and Delftia acidovorans, together with bean pod mottle virus (BPMV), shape soybean ...
