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

New Phytologist, EarlyView.
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.

Dose-Dependent Effect of the Polyamine Spermine on Wheat Seed Germination, Mycelium Growth of Fusarium Seed-Borne Pathogens, and In Vivo Fusarium Root and Crown Rot Development

Agriculture
Wheat (Triticum aestivum L.) is a crucial global food crop. The intensive crop farming, monoculture cultivation, and impact of climate change affect the susceptibility of wheat cultivars to biotic stresses, mainly caused by soil fungal pathogens ...

Spermine modulates fungal morphogenesis and activates plasma membrane H+-ATPase during yeast to hyphae transition

Biology Open, 2018
Polyamines play a regulatory role in eukaryotic cell growth and morphogenesis. Despite many molecular advances, the underlying mechanism of action remains unclear.

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

Plant Biotechnology Journal, EarlyView.
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 ...

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

Plant Biotechnology Journal, EarlyView.
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.

Methyl Jasmonate Seed Priming Mitigates the Defence‐Growth Trade‐Off and Tailors Plant Response to Specific Pests

Plant, Cell &Environment, EarlyView.
ABSTRACT Seed defence priming is emerging as a novel, cost‐efficient and environmentally safe tool for pest management. It has been proposed as a means to uncouple the defence‐growth trade‐off in plants by enhancing defence responses with minimal fitness costs, but the mechanisms underlying this role remain elusive.

Geographic provenance and environmental growing conditions as factors influencing phytochemical composition of Arabica green coffee beans

Plant Biology, EarlyView.
Growth environment strongly influences green coffee bean biochemistry, linking phytochemical composition to adaptation under abiotic stress. Abstract This study explores how bioactive compounds in green coffee beans (Coffea arabica L.) vary across different geographic regions, addressing the key question of how environmental factors shape coffee ...

Polyamine stress at high pH in Escherichia coli K-12

BMC Microbiology, 2005
Background Polyamines such as spermine and spermidine are required for growth of Escherichia coli; they interact with nucleic acids, and they bind to ribosomes. Polyamines block porins and decrease membrane permeability, activities that may protect cells

Plasma proteomic profiling and molecular clustering reveal immune‐defined prognostic subtypes in lung adenocarcinoma

International Journal of Cancer, Volume 158, Issue 4, Page 858-865, 15 February 2026.
What's new? Lung adenocarcinoma shows considerable heterogeneity in disease progression and therapeutic response. Here, the authors analyzed tumor samples through proteomic profiling and applied network‐based clustering. They identified two distinct patient groups with different demographic, clinical, and molecular characteristics.

Spermine inhibits Endoplasmic Reticulum Stress - induced Apoptosis: a New Strategy to Prevent Cardiomyocyte Apoptosis

Cellular Physiology and Biochemistry, 2016
Background/Aims: Endoplasmic reticulum stress (ERS) plays an important role in the progression of acute myocardial infarction (AMI), in part by mediating apoptosis.
