Transporter-mediated depletion of extracellular proline directly contributes to plant pattern-triggered immunity against a bacterial pathogen

Nature Communications
Plants possess cell surface-localized immune receptors that detect microbe-associated molecular patterns (MAMPs) and initiate defenses that provide effective resistance against microbial pathogens.

Pre‐diagnostic immunological markers of bacterial translocation and liver cancer risk: A nested case–control analysis of 12 prospective cohorts

International Journal of Cancer, Volume 158, Issue 7, Page 1801-1812, 1 April 2026.
What's new? Disruption of the gut–liver axis has been suggested to play an important role in liver carcinogenesis. However, limited prospective research has explored associations between potentially harmful gut‐derived bacterial products and liver cancer risk.

Amino Acid Sequence of Bacterial Microbe-Associated Molecular Pattern flg22 Is Required for Virulence

Molecular Plant-Microbe Interactions, 2008
Flagellin proteins derived from Pseudomonas syringae pv. tabaci 6605 and flg22Pa (QRLSTGSRINSAKDDAAGLQIA), one of the microbe-associated molecular patterns (MAMP) in bacterial flagellin, induce cell death and growth inhibition in Arabidopsis thaliana. To

Comparative conventional- and quantum dot-labelling strategies for LPS binding site detection in Arabidopsis thaliana mesophyll protoplasts

Frontiers in Plant Science, 2015
Lipopolysaccharide (LPS) from Gram-negative bacteria is recognized as a microbe-associated molecular pattern (MAMP) and not only induces an innate immune response in plants, but also stimulates the development of characteristic defense responses. However,

Bacillus velezensis 83 protects Arabidopsis thaliana against Botrytis cinerea by triggering JA‐, and SA‐dependent induced systemic resistance

Pest Management Science, Volume 82, Issue 3, Page 2532-2540, March 2026.
B. velezensis 83 protects the plant against B. cinerea, accumulating acetoin and activating jasmonic acid‐ and salicylic acid‐mediated defense responses. Abstract BACKGROUND Modern agriculture is based on the application of synthetic agrochemicals to control multiple abiotic and biotic stresses.

Beauveria Bassiana Triggers Soybean Systemic Resistance and Causes Sublethal Effects in Spodoptera frugiperda

Entomologia Experimentalis et Applicata, Volume 174, Issue 3, Page 236-250, March 2026.
The interaction of soybean plant and the endophytic microorganism Beauveria bassiana was evaluated by inoculating a single trifoliate leaf. The effects of this inoculation on the herbivory, larval development, and life traits of Spodoptera frugiperda were measured.

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.
