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

Plant 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,

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Mechanisms of Gui Zhi Fu Ling Formula in Liver Fibrosis: Metabolomics and Gut Microbiota Analysis

eFood, Volume 7, Issue 3, June 2026.
Our study was based on the efficacy of the phenotype in an animal model and used multi‐omics to explore the mechanism of action of the compound. We found that Gui Zhi Fu Ling Formula may ameliorate hepatic fibrosis potentially associated with increased hepatic EPA and the expression of gut Pseudomonas.
