Cupriavidus metallidurans: a species-non-specific and multifaceted plant growth-promoting bacteria.
Article in BMC plant biology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Here we report growth promoting effects of Cupriavidus metallidurans on plants, and provide evidence for the underlying mechanisms of the growth promoting effects. In a series of greenhouse experiments on tomato, maize, and wheat, complemented with genetic analysis of Arabidopsis mutants, we tested the effects of the bacteria on seed germination, root and shoot growth, metal uptake, gas exchange parameters, and stomatal and xylem traits in maize, wheat, and tomato plants. Results showed that the bacteria substantially accelerate seed germination, increase shoot and root biomass, enhance photosynthetic performance, acidify the rhizosphere, increase metal uptake, and modulate stomatal and xylem traits. Analysis of Arabidopsis mutants impaired in auxin or ethylene perception and signaling revealed that the growth promoting effects of the bacteria and accelerating seed germination is independent of auxin and ethylene. We conclude that the bacteria acidify the rhizosphere and thereby increase metal uptake. It increases stomatal density and xylem area leading to increased stomatal conductance and hydraulic conductivity, leading to increased photosynthesis. Altogether, our data suggest C. metallidurans as a plant growth-promoting bacteria with striking abilities to manipulate different plant traits including stomatal density and xylem structure.
