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.

Ectopic Expression of ScALDH21 From a Desert Moss Enhances Cotton Resistance to Verticillium Wilt via the Modulation of Jasmonates and Phenylpropanoid Pathways

Plant Biotechnology Journal, EarlyView.
ABSTRACT Biotic stresses, particularly Verticillium wilt (VW), lead to a global decline in cotton yields. Here, we demonstrate that ectopic expression of ScALDH21, a gene from the desiccation‐tolerant moss Syntrichia caninervis Mitt. and absent in angiosperms, enhances cotton's resistance to VW.

Virocell Necromass Provides Limited Plant Nitrogen and Elicits Rhizosphere Metabolites That Affect Phage Dynamics

Plant, Cell &Environment, EarlyView.
ABSTRACT Bacteriophages impact soil bacteria through lysis, altering the availability of organic carbon and plant nutrients. However, the magnitude of nutrient uptake by plants from lysed bacteria remains unknown, partly because this process is challenging to investigate in the field.

Volatile Organic Compounds Emitted by Fungi Have Substantial Effects on Growth and Disease Resistance in Arabidopsis thaliana

Plant, Cell &Environment, EarlyView.
ABSTRACT Volatile organic compounds (VOCs) emitted by certain fungi have previously been suggested to modulate plant development and their response to stresses. While some fungal species, such as Trichoderma harzianum, are known to produce VOCs, the production of VOCs in other phylogenetically divergent species, such as Mucor mucedo, was previously ...

A Comparative Study of the Radical-scavenging Activity of the Phenolcarboxylic Acids Caffeic Acid, p-Coumaric Acid, Chlorogenic Acid and Ferulic Acid, With or Without 2-Mercaptoethanol, a Thiol, Using the Induction Period Method

Molecules, 2008
Phenolcarboxylic acid antioxidants do not act in vivo as radical-scavengers in isolation, but rather together with GSH (glutathione), a coantioxidant, they constitute an intricate antioxidant network.

Novel Amino Acid Changes Increase Phosphoenolpyruvate Carboxylase Output in planta

Plant, Cell &Environment, EarlyView.
ABSTRACT Characterization of previously reported Arabidopsis mutants with increased aluminum (Al) resistance (alr) resulting from greater release of Al‐chelating malate identified three unique amino acid substitutions that each impacts PHOSPHOENOLPYRUVATE CARBOXYLASE 1, a key anaplerotic carbon fixation enzyme.
