Effects of microtubule agents on the spatial and electrical properties of the plasma membrane inChara corallina.
Article in Planta, 1990. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The freshwater algaChara corallina Klein ex Willd., em. R.D.W. (=C. australis R.Br.) develops alternating outward (acid) and inward (alkaline) current areas on its surface when illuminated. Exposure of cells to vinblastine, colchicine, or oryzalin caused a reduction in and a shifting of this extracellular current pattern. Removal of these agents from the bathing media resulted in regeneration of the initial current profile. Because these agents all affect tubulin, microtubules may be responsible for orchestrating the transmembrane currents responsible for the acid and alkaline banding phenomenon. Analysis of the membrane potential showed a fast depolarization after vinblastine exposure; however, analysis of the current-voltage curve did not show a change in membrane conductance. A 30-min colchicine treatment decreased the conductance of the plasma membrane with either an hyperor a depolarization in the membrane potential. In contrast, although a 9-h exposure to oryzalin caused a major reduction in the extra-cellular current pattern, only minor changes were observed in the membrane potential and conductance. However, in the presence of oryzalin, the time constants in the light response of the membrane potential increased over this 9-h period. Collectively, these results implicate an involvement of microtubules in spatial control of plasma-membrane transport events inC. corallina.
