Rare Taxa Exhibit Disproportionate Cell-Level Metabolic Activity in Enriched Anaerobic Digestion Microbial Communities

mSystems, 2019
Microbial communities are composed of populations with vastly different abundances and levels of metabolic and replicative activity, ranging from actively metabolizing and dividing to dormant or nonviable.

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Structural insights into xyloglucan recognition by an ABC transporter from a Gram‐positive, thermophilic bacterium

The FEBS Journal, EarlyView.
Athe_2052 is an ABC transporter substrate‐binding protein that recognizes xyloglucan heptasaccharide (XXXG), a soluble breakdown product of plant xyloglucan. The crystal structure of Athe_2052, together with binding assays and computational modeling, shows how XXXG is recognized by this sugar transporter.

Ecological and genomic variation in ectomycorrhizal fungal exploration types

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EMF) produce mycelia with variable extension and complexity, which can be classified according to soil ‘exploration types’ (ETs). ETs have received attention as one of the few mycorrhizal trait frameworks, but without an empirical classification of ET functional diversity and environmental preferences, understanding and ...

A MYB‐Related Transcriptional Module Cooperatively Represses Xylem Development in Poplar

Plant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors play crucial roles in regulating plant growth and development, but the functions of the MYB‐related subfamily in woody plants remain poorly understood. In this study, we characterized PagMYBR028, an MYB‐related transcription factor from poplar ‘84 K’ (Populus alba × Populus glandulosa), which was predominantly ...

Simplified, High Yielding Extraction of Xylan/Xylo-Oligosaccharides from Palmaria palmata: The Importance of the Algae Preservation Treatment

Marine Drugs
The complex plant cell wall heteropolysaccharide xylan, and its breakdown products xylo-oligosaccharides and xylose, are value-added compounds with a plethora of potential applications in diverse areas.

Multiplexed Engineering of Disease Resistance and Lodging Tolerance in Wheat Via a Single Xylan Modifying Glycosyltransferase

Plant Biotechnology Journal, EarlyView.
ABSTRACT Breeding crops with robust disease resistance often compromises yield, a persistent challenge in agricultural improvement. We report that modifying cell wall architecture through a xylan‐specific glycosyltransferase successfully breaks this trade‐off in wheat.

SbWRKY62 Coordinates With SbERF096 to Activate Pterostilbene Biosynthesis and Targets a Xylanase Inhibitor Protein for Anthracnose Resistance in Sorghum

Plant, Cell &Environment, EarlyView.
ABSTRACT Sorghum anthracnose caused by Colletotrichum sublineola (C. sublineola) is a destructive disease leading to severe crop damages. Pterostilbene is a phytoalexin that contributes to defence responses in sorghum, but the transcriptional regulation of its biosynthesis remained poorly understood.

Cellulose Nanofibril (CNF) Films and Xylan from Hot Water Extracted Birch Kraft Pulps

Applied Sciences, 2019
The effects of xylan extraction from birch kraft pulp on the manufacture and properties of cellulose nanofibril (CNF) films were here investigated. Hot water extractions of bleached and unbleached kraft pulps were performed in a flow-through system to ...
