Pressure regulation of the electrical properties of growing Arabidopsis thaliana L. root hairs.

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
Actively growing Arabidopsis thaliana L. (Columbia wild type) root hairs were used to examine the interplay between cell turgor pressure and electrical properties of the cell: membrane potential, conductance, cell-to-cell coupling, and input resistance. Pressure was directly modulated using a pressure probe or indirectly by changing the extracellular osmolarity. Direct modulation of pressure in the range of 0 to about 15 x 10(5) Pa (normal turgor pressure was 6.8 +/- 2.0 x 10(5) Pa, n = 29) did not affect the membrane potential, conductance, coupling, or input resistance. Indirect modulation of turgor pressure by adding (hyperosmotic) or removing (hypo-osmotic) 200 mM mannitol/sorbitol affected the potential and conductance but not cell-to-cell coupling. Hypo-osmotic treatment depolarized the potential about 40 mV from an initial potential of about -190 mV and increased membrane conductance, consistent with an increase in anion efflux from the cell. Hyperosmotic treatment hyperpolarized the cell about 25 mV from the same initial potential and decreased conductance, consistent with a decline in cation influx. The results are likely due to the presence of an "osmo-sensor," rather than a "turgor-sensor," regulating the cell's response to osmotic stress.
