Proteomic Analysis Infers Optimized ATP-Production in Guard Cell Mitochondria.
Article in Physiologia plantarum. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Guard cells are highly specialised leaf cells which regulate leaf transpiration and carbon fixation. As such, they are instrumental in balancing water use efficiency and photosynthetic activity. This unique function of guard cells requires them to quickly accumulate solutes for ATP-dependent stomatal opening, but how this affects mitochondrial energy metabolism remains elusive. Using cell-type-specific affinity purification of Arabidopsis thaliana guard cell and mesophyll cell mitochondria, we aim at unravelling the enzymatic configuration of guard cell mitochondria in order to provide a first glance at the metabolic properties of these specialised organelles. When compared to their mesophyll cell counterparts, the use of alternative substrates for NADH production, a shift away from non-proton pumping respiratory enzymes, and a lower NADH re-oxidation rate suggest a specialised mode of ATP production in guard cell mitochondria. In addition, a lowered abundance of the mitochondrial import machinery also indirectly implies lower protein turnover rates in these organelles.
