Microbial Biostimulants for Drought Resilience in Plants: Mechanisms, Plant-Microbiome Interactions, and Sustainable Agricultural Applications.
Review in Plants (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Drought stress is one of the most significant challenges for global agriculture, adversely affecting crop yields and food security. In recent years, microbial biostimulants have emerged as a promising solution to enhance plant resilience against such abiotic stresses. This review explores the mechanisms by which microbial biostimulants, including beneficial bacteria and fungi, confer drought tolerance in plants. Key interactions between plants and their associated microbiomes are highlighted, emphasizing the roles of root-associated microbes in promoting plant growth, nutrient uptake, and stress mitigation. We examine microbial-induced plant responses, including improved water relations, photosynthetic performance, and osmotic adjustment. Additionally, the review examines the sustainability of microbial biostimulant use in agricultural practices, addressing their potential to reduce reliance on chemical inputs and improve soil health. Evidence from field studies across diverse crops is also discussed, highlighting the potential of microbial biostimulants to improve plant performance and yield stability under water-limited conditions while emphasizing the context-dependent nature of their efficacy. Furthermore, we underscore the importance of microbial diversity and community composition in maximizing the benefits of biostimulants. By integrating microbial biostimulants into conventional agricultural practices, farmers can enhance drought resilience, thereby contributing to sustainable food production systems. This review aims to provide a comprehensive understanding of the interactions between microbial biostimulants and plants under drought stress, and to highlight future research directions for optimizing their use in sustainable agriculture.
