Molecular mechanism of endophytic bacteria DX120E regulating polyamine metabolism and promoting plant growth in sugarcane

Frontiers in Plant Science
IntroductionSugarcane endophytic nitrogen-fixing bacterium Klebsiella variícola DX120E displayed broad impact on growth, but the exact biological mechanism, especially polyamines (PAs) role, is still meager.MethodsTo reveal this relationship, the content

Weight Loss During Obesity Provokes Asparaginase‐Associated Liver Steatosis and Endoplasmic Reticulum Stress

The FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Lean mice and DIO mice were fed either a low‐fat maintenance diet (MD) or a high‐fat obesogenic diet (OD) during pegylated asparaginase exposure. OD exacerbated asparaginase‐induced weight loss and modestly increased liver triglycerides and ER stress in lean mice.

Preharvest potassium silicate treatments influence the morphological appearance and enhance nutritional composition of almond kernels

Journal of the Science of Food and Agriculture, Volume 106, Issue 5, Page 2800-2807, 30 March 2026.
Abstract BACKGROUND The almond industry requires new strategies to improve almond kernel quality. The use of biostimulants such as potassium silicate (KSi) is an eco‐friendly and non‐polluting alternative. The aim of this work was to investigate the preharvest application of KSi solutions at 2 and 20 mmol L−1 to ‘Peraleja’ almond trees during two ...

Review of Amino Acid Foliar Application as a Stress Mitigation Strategy: Unraveling the Protective Mechanisms Against Abiotic Stress

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT The foliar application of amino acids offers a promising strategy to mitigate multiple abiotic stresses—drought, salinity, heat and heavy metals—by enhancing plant physiological, biochemical and molecular responses. This review synthesises recent advances in understanding how external amino acids function as bio‐stimulants, focusing on ...

Polyamine Catabolism Revisited: Acetylpolyamine Oxidase Plays a Minor Role due to Low Expression

Cells
Biogenic polyamines are ubiquitous compounds. Dysregulation of their metabolism is associated with the development of various pathologies, including cancer, hyperproliferative diseases, and infections.

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.

Polyamine oxidase‐mediated killing of African trypanosomes

Parasite Immunology, 1982
African trypanosomes, Trypanosoma brucei brucei, T. vivax and T. congolense, were killed when incubated in vitro with ruminant sera in the presence of exogeneous spermidine, and were non‐infective for mice. Purified polyamine oxidase in the presence of spermidine‐mediated similar killing of trypanosomes.
