Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Metagenomic insights into the carbohydrate-active enzymes carried by the microorganisms adhering to solid digesta in the rumen of cows. [PDF]

PLoS ONE, 2013
The ruminal microbial community is a unique source of enzymes that underpin the conversion of cellulosic biomass. In this study, the microbial consortia adherent on solid digesta in the rumen of Jersey cattle were subjected to an activity-based ...

Lactobacillus acidophilus Metabolizes Dietary Plant Glucosides and Externalizes Their Bioactive Phytochemicals [PDF]

, 2017
Therapeutically active glycosylated phytochemicals are ubiquitous in the human diet. The human gut microbiota (HGM) modulates the bioactivities of these compounds, which consequently affect host physiology and microbiota composition.

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

Integrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing

Characterisation of a phylogenetically distinct PL25 family ulvan lyase from a seaweed biomass enriched metagenome

The FEBS Journal, EarlyView.
Ulvan is a polysaccharide available from green seaweed with beneficial properties for various applications. The full potential of ulvan requires enzymatic degradation of the polymer, thus producing ulvan oligosaccharides. This study expands the armoury of characterised ulvan lyases.

Molecular Dissection of Xyloglucan Recognition in a Prominent Human Gut Symbiont

mBio, 2016
Polysaccharide utilization loci (PUL) within the genomes of resident human gut Bacteroidetes are central to the metabolism of the otherwise indigestible complex carbohydrates known as “dietary fiber.” However, functional characterization of PUL lags ...

The Role of Petrimonas mucosa ING2-E5A^T in Mesophilic Biogas Reactor Systems as Deduced from Multiomics Analyses

Microorganisms, 2020
Members of the genera Proteiniphilum and Petrimonas were speculated to represent indicators reflecting process instability within anaerobic digestion (AD) microbiomes.
