The Effect of Myrtacine and Celastrol‐Enriched Extract on Cutibacterium acnes Extracellular Vesicles

open access: yesInternational Journal of Dermatology, EarlyView.
Myrtacine alone, Celastrol‐enriched extract alone, or the combination of both ingredients were added to the culture medium either before (preventive condition) or after (modulating condition) incubation with C. acnes IA1 extracellular vesicles (EVs) from healthy and acne skin in immortalized keratinocytes (HaCaT cells) and human skin explants.

Distinct Defence Mechanisms of Allelopathic Rice Against Quinclorac‐Susceptible and ‐Resistant Barnyardgrass: Involvement of Specific Metabolites and Rhizosheath Microbiota

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,

Unfolding Plant Defence: Endoplasmic Reticulum Stress Signalling at the Plant‐Pathogen Interface

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The endoplasmic reticulum (ER) stress response, a conserved proteostasis network, has emerged as a central hub that reprograms plant immunity during pathogen attack. This review synthesises how plants harness ER‐stress signalling to mount multilayered defences and how pathogens have evolved counterstrategies to subvert these pathways.
