Summary
This narrative review synthesises current understanding of how plant hormones orchestrate root exudation—a critical process mediating plant-soil interactions. The authors examine eight major hormone classes and their roles in regulating exudate composition, rhizosphere microbial associations, nutrient mobilisation, and stress responses. The review identifies knowledge gaps, particularly the limited integration of controlled laboratory studies with field-based complexity, and proposes emerging tools such as hormone-responsive biosensors and metabolomics to advance agricultural application.
Regional applicability
The review is a synthesis of mechanistic plant biology with potential global relevance; however, it does not report empirical field data and thus regional applicability to United Kingdom agricultural conditions cannot be directly assessed from this abstract. Translation to UK farming contexts would require integration with field-based studies in temperate climates and validation under local soil and climatic conditions.
Key measures
Qualitative synthesis of hormone-regulated exudate profiles; mechanisms of hormone signalling in root development and exudation; effects on nutrient acquisition, soil structure, microbial dynamics, and plant stress resilience
Outcomes reported
The study synthesised recent findings on how eight major plant hormones (auxins, cytokinins, gibberellins, abscisic acid, ethylene, jasmonates, salicylic acid, brassinosteroids, and strigolactones) regulate root exudate composition and rhizosphere interactions. It examined hormone signalling pathways, crosstalk mechanisms, and their roles in nutrient mobilisation, stress defence, and beneficial microbial associations.
