A synthetic community promotes macadamia growth via root‐microbe interactions and systemic plant responses

iMetaOmics, EarlyView.
We employed an 18‐month pot experiment and an integrated multi‐omics approach to elucidate the potential mechanisms underlying synthetic community (SynCom)‐mediated macadamia growth promotion. SynCom inoculation enhanced soil nitrogen cycling and potential nutrient (e.g., iron) acquisition.

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Local renin angiotensin system and sperm DNA fragmentation

Asian Journal of Andrology, 2022
The renin angiotensin system (RAS) appears to influence male fertility at multiple levels. In this work, we analyzed the relationship between the RAS and DNA integrity.

Nitrogen Enrichment Enhances Soil Multifunctionality Through Distinct Drivers Across Urban, Suburban, and Rural Forests

Land Degradation &Development, EarlyView.
ABSTRACT The accelerating pace of urban expansion has profoundly reshaped urban–rural ecosystems, altering soil environments and impairing key ecological services. However, the combined impacts of urban expansion and atmospheric nitrogen (N) deposition on soil multifunctionality—the capacity to sustain multiple ecological processes—remain poorly ...

The internal sequence of the peptide-substrate determines its N-terminus trimming by ERAP1.

PLoS ONE, 2008
BackgroundEndoplasmic reticulum aminopeptidase 1 (ERAP1) trims N-terminally extended antigenic peptide precursors down to mature antigenic peptides for presentation by major histocompatibility complex (MHC) class I molecules.

Alpine Secondary Forest Types Influence Soil Microbial Community Structure and Enzyme Activities on the Eastern Qinghai–Tibet Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial communities and enzyme activities influence soil functions and tree growth in ecologically fragile alpine regions. However, differences in soil microbial communities among secondary forests remain poorly understood in the Qinghai–Tibet Plateau.

Root Order Dependent Changes in Fine‐Root Substrate and Soil Environment Regulate Soil Organic Nitrogen Fractions Under Acid Rain and Nitrogen Deposition

Land Degradation &Development, EarlyView.
ABSTRACT Acid rain and nitrogen deposition are important environmental stressors affecting soil nitrogen cycling in subtropical forests, whereas fine‐root decomposition represents a major pathway for soil organic nitrogen (SON) input and transformation.

Development of Hydroxamate Derivatives Containing a Pyrazoline Moiety as APN Inhibitors to Overcome Angiogenesis

Molecules, 2022
Aminopeptidase N (APN) was closely associated with cancer invasion, metastasis, and angiogenesis. Therefore, APN inhibitors have attracted more and more attention of scientists as antitumor agents.

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Anti-Inflammatory and Antitumor Effects of Hydroxytyrosol but Not Oleuropein on Experimental Glioma In Vivo. A Putative Role for the Renin-Angiotensin System

Biomedicines, 2018
Functional roles of the angiotensin peptides of the renin-angiotensin system (RAS) cascade can be analyzed through their corresponding proteolytic regulatory enzymes aspartyl aminopeptidase (ASAP), aminopeptidase A (APA), aminopeptidase B (APB ...
