Greenhouse gas emission and cadmium contamination in rice paddies: research progresses in trade-off relationships, influencing factors and synergistic mitigation measures

Frontiers in Sustainable Food Systems
Rice paddies, critical for global food security, confront dual challenges of greenhouse gas (GHG, e.g., CH4, N2O) emissions and cadmium (Cd) contamination.

Alteration of soil carbon and nitrogen pools and enzyme activities as affected by increased soil coarseness [PDF]

Biogeosciences, 2017
Soil coarseness decreases ecosystem productivity, ecosystem carbon (C) and nitrogen (N) stocks, and soil nutrient contents in sandy grasslands subjected to desertification. To gain insight into changes in soil C and N pools, microbial biomass, and enzyme

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Integrative analysis of endogenous phytohormones and transcriptomics reveals mechanism of light-induced callus formation in tea (Camellia sinensis) cuttings

BMC Plant Biology
Backgroud Cutting is the mainly asexual propagation method for tea plant, and moreover, callus formation is a key point for the survival rate of tea cuttings. As reported, light is crucial for callus formation of tea cuttings via influencing phytohormone

Volatile metabolomics highlights tea trichome's positive contribution to aroma and quality of white tea

Current Research in Food Science
Tea trichomes, rich in secondary metabolites, are hypothesized to significantly influence white tea aroma, yet their biochemical contributions remain unclear. This study investigated the volatile profiles of tea trichome and tea body across six white tea

Soil Fertility and Nutrient Management on Spodosol for Oil Palm [PDF]

, 2010
The research was carried out in Oil Palm Plantation in Ngabang, Landak Distric, West Kalimantan in May 2008. Composite soil samples were taken from the soils, in which the oil palms indicated the nutrient disorders. The aims of the research were to study

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Exploring the Use of High-Resolution Satellite Images to Estimate Corn Silage Yield Within Field

Remote Sensing
Corn (Zea mays L.) silage yield monitor data offer crucial insights into spatial and temporal yield variability. However, equipment’s sensor malfunctioning can result in data loss, and yield sensor systems are expensive to purchase and maintain.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.
