Summary

This meta-analysis synthesises experimental evidence on the role of arbuscular mycorrhizal fungi (AMF) in mediating plant responses to drought stress, with particular focus on biomass production, root morphology and nutrient acquisition. By pooling data across multiple peer-reviewed studies, the paper provides quantitative estimates of the benefit of AMF inoculation under water-deficit conditions, offering a more robust assessment than individual trials. The findings likely indicate that AMF colonisation confers significant positive effects on host plant performance under drought, with implications for sustainable crop management in water-limited environments.

UK applicability

Although the meta-analysis draws on global experimental data, the findings are broadly applicable to UK arable and horticultural systems where summer drought stress is an increasing concern under climate change. The evidence supporting AMF-mediated improvements in nutrient uptake and root development is relevant to UK efforts to reduce synthetic fertiliser inputs and improve crop resilience.

Key measures

Plant shoot and root biomass; root length, root volume and root surface area; nutrient uptake (likely N, P, K and micronutrients); effect size estimates (e.g. Hedges' d or response ratio) under drought versus well-watered conditions

Outcomes reported

The meta-analysis quantified the effects of arbuscular mycorrhizal fungi (AMF) inoculation on plant biomass, root morphological traits, and macro- and micronutrient uptake under drought stress conditions. Effect sizes were likely pooled across multiple crop species and experimental studies to assess the overall benefit of AMF colonisation under water-limited conditions.
