Host-selected mutations converging on a global regulator drive an adaptive leap towards symbiosis in bacteria [PDF]

, 2017
Host immune and physical barriers protect against pathogens but also impede the establishment of essential symbiotic partnerships. To reveal mechanisms by which beneficial organisms adapt to circumvent host defenses, we experimentally evolved ...

Signalling and regulation of plant development by carbon/nitrogen balance

Physiologia Plantarum, Volume 177, Issue 2, March/April 2025.
Abstract The two most abundant macronutrients in plant cells are carbon (C) and nitrogen (N). Coordination of their cellular metabolism is a fundamental factor in guaranteeing the optimal growth and development of plants. N availability and assimilation profoundly affect plant gene expression and modulate root and stem architecture, thus affecting ...

From Sweetness to Mouthfeel: A Review on Overcoming Sensory Barriers in Sugar‐Free Beverages

International Journal of Food Science, Volume 2025, Issue 1, 2025.
Background Over recent decades, considerable research has focused on understanding sweet taste mechanisms and developing new noncarbohydrate sweeteners due to rising noncommunicable diseases. New regulations limiting high sugar levels in food and beverages have driven innovation towards reduced‐sugar and sugar‐free products, often using noncarbohydrate

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 21: Suitability of taxonomic units notified to EFSA until September 2024

EFSA Journal, Volume 23, Issue 1, January 2025.
Abstract The qualified presumption of safety (QPS) process was developed to provide a safety assessment approach for microorganisms intended for use in food or feed chains. In the period covered by this Statement, no new information was found that would change the status of previously recommended QPS taxonomic units (TUs).

Membrane-bound glycerol dehydrogenase catalyzes oxidation of D-pentonates to 4-keto-D-pentonates, D-fructose to 5-keto-D-fructose, and D-psicose to 5-keto-D-psicose [PDF]

Bioscience, Biotechnology, and Biochemistry, 2017
Abstract A novel oxidation of D-pentonates to 4-keto-D-pentonates was analyzed with Gluconobacter thailandicus NBRC 3258. D-Pentonate 4-dehydrogenase activity in the membrane fraction was readily inactivated by EDTA and it was reactivated by the addition of PQQ and Ca2+. D-Pentonate 4-dehydrogenase was purified to two different subunits,

alpha-lipoic acid suppresses 6-hydroxydoparnine-induced ROS generation and apoptosis through the stimulation of glutathione synthesis but not by the expression of heme oxygenase-1 [PDF]

, 2008
We previously reported that the generation of reactive oxygen species (ROS) is the initial event in cell death induced by 6-hydroxydopamine (6-OHDA), an experimental model of Parkinsonism.

Exploiting Archaeal/Thermostable Enzymes in Synthetic Chemistry: Back to the Future?

ChemCatChem, Volume 16, Issue 21, November 11, 2024.
Thermostable and (hyper)thermophilic enzymes offer important opportunities for innovative, stereoselective and sustainable chemistry transformations. Many of these are archaeal enzymes that have evolved to operate under extreme conditions, including at elevated temperature.
