Enhancing plant drought tolerance through exogenous nitric oxide: a comprehensive meta-analysis.
Synthesis in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
backgroundDrought stress severely impacts plant growth and agricultural productivity, necessitating strategies to enhance drought tolerance. This meta-analysis synthesizes data from 48 peer-reviewed studies to evaluate the effects of exogenous nitric oxide (NO) on plant growth, photosynthesis, antioxidant defense, and osmoregulation under drought conditions.
resultsResults show that NO significantly improves shoot length, root length, shoot dry weight, and root dry weight by 66.60%, 29.38%, 26.71%, and 16.17%. Photosynthetic rate, stomatal conductance, intercellular CO₂, Leaf relative water content, total chlorophyll, chlorophyll a and b was also improved by 17.98%, 67.95%, 12.12%, 10.20%, 19.68%, 52.26%, and 39.91%, respectively. Antioxidant enzyme activities, including superoxide dismutase, catalase, peroxidase, and ascorbate peroxidase, were significantly elevated by 13.69%, 22.60%, 16.98%, and 19.33%, respectively. Oxidative stress markers, including hydrogen peroxide, superoxide, and malondialdehyde, were reduced by 18.63%, 22.01%, and 18.22%, respectively. Osmotic regulators, including proline, soluble sugars, and soluble proteins, were significantly increased by 17.01%, 18.34%, and 30.40%. Subgroup analyses reveal that NO's effectiveness is influenced by environmental factors, plant species, and application methods.
conclusionsThis meta-analysis confirms that exogenous NO significantly improves the growth, photosynthetic efficiency, antioxidant defense, and osmotic regulation of plant under drought stress. The heterogeneity of NO's effects under different conditions highlights the importance of improving application methods, concentrations, and environmental conditions. These findings encourage focused research and application strategies to maximize the benefits of NO in enhancing crop resilience, and promoting sustainable agricultural practices.
