Summary
This review examines the role of plant growth-promoting rhizobacteria (PGPR) as a biological strategy for alleviating drought stress in agricultural plants. It likely synthesises current understanding of the mechanisms through which PGPR — including ACC deaminase activity, phytohormone modulation, and enhanced root architecture — improve plant resilience under water-deficit conditions. The paper contributes to a growing body of literature exploring sustainable, microbiome-based alternatives or complements to chemical inputs for climate adaptation in agriculture.
UK applicability
Whilst the review is likely global in scope, the findings are broadly applicable to UK arable and horticultural systems facing increasing drought frequency due to climate change, and may inform future UK agri-environment or soil health policy on biological soil inoculants.
Key measures
Drought tolerance mechanisms; root colonisation; osmotic adjustment; phytohormone production; reactive oxygen species scavenging; plant biomass and growth parameters under water stress
Outcomes reported
The review examines mechanisms by which plant growth-promoting rhizobacteria (PGPR) confer drought tolerance in plants, likely covering physiological, biochemical, and molecular responses. It reportedly assesses the efficacy of PGPR inoculation in improving plant survival, growth, and productivity under water-deficit conditions.
