Mitochondrial Respiratory Metabolism in Salt‐Stressed Barley (Hordeum vulgare): TCA Cycle Activation With Limited GABA Shunt Engagement

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants maintain energy balance under salinity stress through increased respiration and energy use, processes also associated with reactive oxygen species generation. Although respiration imposes a high energy cost, mitochondrial respiration and the tricarboxylic acid (TCA) cycle activity are vital for ATP production and for providing electron ...

Beyond protein synthesis: the emerging role of arginine in poultry nutrition and host-microbe interactions

Frontiers in Physiology
Arginine is a functional amino acid essential for various physiological processes in poultry. The dietary essentiality of arginine in poultry stems from the absence of the enzyme carbamoyl phosphate synthase-I.

Plant NAOGAT (ArgJ) Structure Reveals Mechanism of Ornithine Biosynthesis, Preference for Acetylornithine and Susceptibility to Mangotoxin

Plant, Cell &Environment, EarlyView.
ABSTRACT Arginine metabolism in plants is targeted by phytopathogens such as Pseudomonas syringae strains, which produce toxins that affect enzymes of plant arginine metabolism, causing devastating infections in crops. In this work, the structural and functional properties of plant N‐acetylornithine glutamate acetyltransferase (NAOGAT), the key ...

The involvement of arbuscular mycorrhizal fungi in modulating polyamine metabolism and low-temperature tolerance enhancement in white clover

Frontiers in Plant Science
Sustained low temperatures can prevent white clover (Trifolium repens L.) from overwintering and regreening, making it difficult to revive the plants in the spring.

Perturbation of Spermine Homoeostasis Uncouples Hypersensitive Cell Death From Systemic Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

Putrescine Plays a Positive Role in Salt-Tolerance Mechanisms by Reducing Oxidative Damage in Roots of Vegetable Soybean

Journal of Integrative Agriculture, 2014
Polyamines play important roles in plant tolerance to environmental stress. With the aim of investigating the possible involvement of putrescine (Put) in salt-tolerance mechanisms in vegetable soybean roots, exogenous Put (10 mmol L−1) and its ...

Müller Glia Subtypes Define Neuro‐Glial Associations and Spatial Morphogen Axes in the Zebrafish Retina

Glia, Volume 74, Issue 11, November 2026.
Zebrafish Müller glia are heterogeneous in the early larval retina. Zebrafish Müller glia subtypes define a spatial axis of retinoic acid metabolism. Neuron‐associated glial programs identified in Zebrafish Müller glia are evolutionarily conserved in mammals. ABSTRACT Müller glia are instrumental macroglia of the vertebrate retina, once thought to be a

Essential Oral Single Nutritional Therapy Products for Inherited Metabolic Diseases: Evidence and Consensus Assessment Using a Modified Delphi Method

Journal of Inherited Metabolic Disease, Volume 49, Issue 6, November 2026.
ABSTRACT Nutritional therapy is critical in managing inherited metabolic diseases (IMDs), and includes specialized diets and single nutritional therapy products (sNTPs) such as vitamins, cofactors, and amino acids. Many sNTPs function as medicines, but are regulated as food (e.g., food supplements), which can limit access, reimbursement, and consistent

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, Volume 179, Issue 3, Page 418-433, November 2026.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...
