Phytosulfokine signalling blocks mycotoxin toxicity in Arabidopsis and mediates suppression of cell death activated by bacterial microbe‐associated molecular patterns

New Phytologist, Volume 249, Issue 5, Page 2515-2530, March 2026.
Summary Fumonisin B1 (FB1) is a mycotoxin that disrupts ceramide biosynthesis and kills plants. Prior activation with bacterial microbe‐associated molecular patterns (MAMPs), such as components of bacterial flagella, effectively suppresses FB1‐induced cell death.

Nitrogen Isotope Fractionation During Nitrate and Ammonium Uptake in Maize: Hydroponic Evidence and Implications for Ecological Investigations

Plant, Cell &Environment, Volume 49, Issue 3, Page 1793-1804, March 2026.
ABSTRACT Understanding nitrogen (N) isotopic fractionation during plant uptake is critical for interpreting δ15N variations in terrestrial ecosystems. We investigated isotopic discrimination during ammonium (NH4+) or nitrate (NO3−) uptake in maize (Zea mays) grown hydroponically under controlled conditions with 0.2 and 2 mM to represent high and low ...

Mild Short‐Term Caloric Restriction Induces Coordinated Changes That Promote Lipid Deposition While Maintaining Thermogenesis Capacity in Interscapular Brown Adipose Tissue of Male Rats

The FASEB Journal, Volume 40, Issue 3, 15 February 2026.
Rats under mild caloric restriction (85% vs. ad libitum) for 2 weeks show metabolic and structural adaptations in iBAT. Caloric restriction increases glycolysis and triglyceride deposition in the tissue, leading to larger lipid droplets. It also reduces mitochondrial iBAT content, while maintaining iBAT thermogenic potential thanks to an increased ...
