Improving the Synthesis of Degradable Cationic Nanogels for Nucleic Acid Delivery

Macromolecular Chemistry and Physics, Volume 227, Issue 1, 15 January 2026.
An improved robust strategy to generate biodegradable, cationic, core‐crosslinked, fully hydrophilic nanogels is presented. The cationic secondary amines of the crosslinker are first converted into hydrophobic Boc‐protected carbamates by a simple one‐pot reaction.

Non‐canonical nitric oxide signalling and DNA methylation: Inflammation induced epigenetic alterations and potential drug targets

British Journal of Pharmacology, Volume 183, Issue 1, Page 24-39, January 2026.
Abstract DNA methylation controls DNA accessibility to transcription factors and other regulatory proteins, thereby affecting gene expression and hence cellular identity and function. As epigenetic modifications control the transcriptome, epigenetic dysfunction is strongly associated with pathological conditions and ageing.

Conserved spatial patterning of gene expression in independent lineages of C4 plants

New Phytologist, Volume 249, Issue 1, Page 24-38, January 2026.
Summary C4 photosynthesis enhances carbon fixation efficiency by reducing photorespiration through the use of an oxygen‐insensitive carboxylase and spatial separation of photosynthesis between mesophyll and bundle sheath cells. The C4 pathway has evolved independently in > 60 plant lineages, but molecular mechanisms underpinning this convergence remain

The architecture of resilience: a genome assembly of Myrothamnus flabellifolia sheds light on desiccation tolerance and sex determination

New Phytologist, Volume 249, Issue 2, Page 1063-1084, January 2026.
Summary Myrothamnus flabellifolia is a dioecious resurrection plant endemic to southern Africa that has become an important model for understanding desiccation tolerance. Despite its ecological and medicinal significance, genomic and transcriptomic resources for the species are limited.

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).

Risks for human health related to the presence of plant lectins in food

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission asked the European Food Safety Authority (EFSA) to assess the risk related to the presence of plant lectins in food. Based on the available evidence, the CONTAM Panel considered only phytohaemagglutinin (PHA), a legume lectin from beans (Phaseolus sp.), for the risk characterisation.
