Urine Metabolism Biomarkers Predict Preterm Infant Adiposity at Hospital Discharge

Molecular Nutrition &Food Research, Volume 70, Issue 6, 29 March 2026.
In this cohort of term and preterm infants, urinary amino acid and acylcarnitine concentrations varied by diabetes in pregnancy exposure and gestational age at birth, and certain patterns of urinary metabolites were differentially related to postnatal adiposity development in preterm infants of women with diabetes in pregnancy. ABSTRACT In infants born

Ions as Architects of DNA Nanostructures: Mechanisms, Simulations, and Technological Frontiers

Small Structures, Volume 7, Issue 3, March 2026.
Ions are not merely passive electrolytes but active regulators of DNA nanostructures. This review shows how ion valence, hydration, and specificity govern electrostatic screening, correlation, and confinement, enabling DNA origami, metallized DNA, nanopores, hydrogels, DNAzymes, molecular machines, and energy devices through integrated experimental and

Temporal Control Over Complex, Simple, and Multiphase Coacervates Using Ureolysis and Ammonium Carbonate Decomposition

ChemSystemsChem, Volume 8, Issue 2, March 2026.
A new strategy for temporal control over simple and complex coacervates is described here. The urea‐urease reaction results in the timed formation and/or destruction of complex coacervates after controllable delays. This strategy is easily adaptable to different time scales and polyelectrolyte pairs.

ODC1 Polyamine Metabolism Drives Prostate Cancer via AKT and Splicing

Journal of Cellular and Molecular Medicine, Volume 30, Issue 5, March 2026.
ABSTRACT Prostate cancer is an aggressive disease with limited quantifiable biomarkers. One gene of interest is ODC1, which encodes ornithine decarboxylase, the rate‐limiting enzyme converting ornithine to putrescine in polyamine metabolism. Although ODC1 is known to be involved in prostate cancer development, exactly how it drives the disease ...

Discrete and cell‐specific hypoxic responses in Arabidopsis roots resolved by single‐nuclei transcriptomics

New Phytologist, Volume 249, Issue 6, Page 2652-2667, March 2026.
Summary With the intensification of unpredictable flooding events because of global warming, there is a need to understand how root cells perceive and respond to oxygen deprivation. The use of high‐throughput single‐nuclei RNA‐sequencing (snRNA‐Seq) allows the examination of gene expression profiles in discrete cell types.

Cell‐Type‐Specific and Variety‐Specific Responses to Salt Stress in Wheat Root Revealed by Single‐Cell Transcriptomics

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1446-1464, March 2026.
ABSTRACT Soil salinization threatens the yield and quality of wheat. Roots are critical for the salt stress response, yet their cell‐type‐specific mechanisms remain unclear. We conducted the first single‐nucleus RNA sequencing analysis of wheat root tips from salt‐sensitive (CS) and ‐tolerant (DK) varieties under salt stress, profiling 188 270 high ...

The Effect of Seed Priming with Polyamine Spermine on Key Photosynthetic Parameters in Fusarium culmorum Infected Winter Wheat

Agronomy
Photosynthesis is a primary plant physiological process, which can easily be affected by various environmental factors, including biotic stressors. The exogenous application of different substances like plant growth regulators might benefit this process ...

New routes for spermine biosynthesis

Journal of Biological Chemistry
The polyamine spermine (Spm) is a flexible linear teraamine found in bacteria and eukaryotes and in all known cases is synthesized from triamine spermidine by addition of an aminopropyl group acquired from decarboxylated S-adenosylmethionine (dcAdoMet).

Induction of Synthetic Apomixis in Two Sorghum Hybrids Enables Seed Yield and Genotype Preservation Over Multiple Generations

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1712-1724, March 2026.
ABSTRACT Induction of apomixis, or clonal reproduction through seed, could economise commercial hybrid seed production and enable smallholder farmers to save and sow hybrid seed. Here, we demonstrate the synthetic induction of apomixis in two sorghum hybrids and show that the clonal hybrid seed can be maintained across multiple seed generations.
