Summary
This review synthesises current mechanistic understanding of drought stress responses in staple crops, covering physiological and molecular pathways including osmotic adjustment, reactive oxygen species management, and abscisic acid signalling. It likely evaluates a range of management approaches — including agronomic, genetic, and biotechnological interventions — for improving drought resilience. The paper is positioned as a forward-looking resource identifying research gaps and practical strategies for securing staple crop productivity under increasingly water-limited conditions.
UK applicability
Whilst the review is international in scope and primarily oriented towards drought-vulnerable regions, its findings are increasingly relevant to UK arable systems as summer drought frequency rises under climate change projections; insights into crop stress physiology and management could inform UK variety selection and agronomic practice.
Key measures
Drought tolerance mechanisms (osmotic adjustment, antioxidant response, stomatal regulation); crop yield under water deficit; stress signalling pathways; management intervention efficacy
Outcomes reported
The review examines physiological, molecular, and biochemical mechanisms by which staple crops respond to drought stress, and evaluates current and emerging management strategies to mitigate yield losses under water deficit conditions.
