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.

Melatonin seed priming: A climate‐smart, green strategy to enhance abiotic stress tolerance in plants

Journal of Integrative Plant Biology, EarlyView.
This review synthesizes how melatonin seed priming preconditions seeds to enhance tolerance against diverse abiotic stresses. It highlights the underlying mechanisms and proposes an integrative roadmap of advanced molecular and breeding tools to design next‐generation, stress‐smart plants.

Determination of Phenolic Acids in Sugarcane Vinasse by HPLC with Pulse Amperometry

Journal of Analytical Methods in Chemistry, 2018
A reversed-phase liquid chromatographic separation with pulsed amperometric detection of phenolic acids at a glassy carbon electrode is described. Chromatographic separation was carried out in isocratic conditions using 0.20 mol·L−1 acetic acid (pH 5.0 ...

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.

Inhibition behaviours of some phenolic acids on rat kidney aldose reductase enzyme: an in vitro study

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
Aldose reductase (AR) inhibitors have vital importance in the treatment and prevention of diabetic complications. In this study, rat kidney AR was purified 19.34-fold with a yield of 3.49% and a specific activity of 0.88 U/mg using DE-52 Cellulose anion ...

Glucosides of Coumarinic and o -Coumaric Acids in the Tonka Bean

Science, 1963
The β-glucosides of coumarinic and o -coumaric acids were detected in extracts of cotyledons, exocarps, and seedling leaves of the tonka bean. The existence of these compounds and the presence of a β-glucosidase having specificity for coumarinyl glucoside suggest that the tonka bean synthesizes coumarin by a pathway

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 ...
