Beneath the Bark: Molecular Determinants of Adaptation and Infection in Bacterial Pathogens of Woody Hosts

Molecular Plant Pathology, Volume 27, Issue 8, August 2026.
Bacterial pathogens colonise woody hosts by integrating metabolic adaptation, effector‐mediated immune suppression, cell wall remodelling and EPS‐ and toxin‐supported persistence. ABSTRACT Bacterial pathogens of woody plants represent a pervasive yet underexplored threat to global agriculture and forestry, causing devastating diseases in fruit trees ...

ERF transcription factor StPti5 is a regulator of endophyte community maintenance in potato

New Phytologist, Volume 251, Issue 3, Page 1344-1360, August 2026.
Summary We have recently identified an ethylene response factor, StPti5, as a susceptibility factor that negatively regulates immune responses to diverse pathogens. Here, we investigated the role of StPti5 in the processes involved in the colonization of potato with beneficial organisms.

Endogenous RALF peptide function is required for powdery mildew host colonization

New Phytologist, Volume 251, Issue 4, Page 2073-2090, August 2026.
Model of RALF‐FER‐dependent effects on powdery mildew sporulation. Summary The receptor kinase FERONIA (FER) is a susceptibility factor for biotrophic powdery mildew fungal pathogens in Arabidopsis thaliana, but the underlying molecular mechanisms remain largely unknown. FER is required for the perception of endogenous RAPID ALKALINIZATION FACTOR (RALF)

Chemical treatment rescues reduced growth of the autoimmune mutant chs3‐2D without compromising its immune responses

Plant Biology, Volume 28, Issue 5, Page 1686-1697, August 2026.
We generated a compound by chemical modification that can efficiently rescue growth without decreasing the immune response of the chs3‐2D autoimmune mutants, thus chemically uncoupling its growth–defence trade‐off. Abstract Plant development in many species including Arabidopsis relies on the accurate balance between growth and defence.

ER-PM tether Syt1 limits cell-to-cell connectivity via plasmodesmata during innate immune responses in Arabidopsis

Cell Reports
Summary: Upon perception of microbe-associated molecular patterns (MAMPs), plants close plasmodesmata (PD) as part of their innate immune responses.

Probiotic Engraftment and Suppression of Canine Otitis Externa Pathogens by Probiotic Ear Drops

Veterinary Dermatology, Volume 37, Issue 4, Page 534-540, August 2026.
Background: Lactobacillaceae have shown promise with their potential to outcompete pathogens and restore a healthy microbial balance in otitis externa (OE). Hypothesis/Objectives: This study aimed to evaluate the presence of viable Lactobacillaceae over time and in vitro ability to inhibit the growth of common OE pathogens.

Spatial IMA1 regulation restricts root iron acquisition on MAMP perception

Nature
Iron is critical during host-microorganism interactions1-4. Restriction of available iron by the host during infection is an important defence strategy, described as nutritional immunity5. However, this poses a conundrum for externally facing, absorptive tissues such as the gut epithelium or the plant root epidermis that generate environments that ...

mamp-ml: A deep learning approach to epitope immunogenicity in plants

Abstract Eukaryotes detect biomolecules through surface-localized receptors, key signaling components. A subset of receptors survey for pathogens, induce immunity, and restrict pathogen growth. Comparative genomics of both hosts and pathogens has unveiled vast sequence variation in receptors and potential ligands, creating an ...

Funktionelle Analyse starker MAMP-responsiver synthetischer Promotoren

, 2015
Microbe-associated molecular pattern (MAMP) are for example molecules from pathogens that upregulate defense genes through specific cis-regulatory sequences. The basis of this work was the previous identification of novel MAMP-responsive cis-sequences from Arabidopsis thaliana. The aim of this work is the functional dissection of the two strongest MAMP-
