Summary
This comprehensive review examines the physiological, biochemical and hormonal mechanisms by which plants respond to and alleviate drought stress. The paper synthesises current understanding of adaptive pathways including osmolyte accumulation, antioxidant defence systems and hormone signalling that enable plant resilience under water limitation. The work provides a framework for understanding drought tolerance mechanisms across plant species.
Regional applicability
Findings are relevant to UK agriculture given increasing drought risk from climate change, particularly in southern and eastern regions. The mechanistic insights may inform breeding and agronomic strategies for crop drought tolerance in variable UK growing conditions.
Key measures
Plant physiological markers (osmotic potential, turgor pressure, stomatal conductance); biochemical indicators (soluble sugars, proline, antioxidant enzyme activity); phyto-hormonal levels (abscisic acid, gibberellins, auxins, cytokinins); drought stress severity indices
Outcomes reported
The study synthesises evidence on how plants' physio-biochemical and phyto-hormonal mechanisms respond to and mitigate drought stress. It likely reviews adaptive responses across plant taxa and examines the roles of plant hormones, osmolytes, antioxidants and other biochemical pathways in drought tolerance.
