Gamma-tubulin is associated with a cortical-microtubule-organizing zone in the developing guard cells of Allium cepa L.
Article in Planta, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
A key event in the differentiation of elliptically shaped guard cells such as those in Allium is the formation of a radial array of cortical microtubules (Mts) which, by controlling the orientation of wall microfibrils, plays an important role in cell shaping. Previous experiments strongly indicated that the array is nucleated in a zone adjacent to the new ventral wall soon after cytokinesis. In order to further clarify the function of this zone, we performed dual immunolocalizations on Allium guard cells with anti-beta-tubulin, to detect Mts, and an antibody to gamma-tubulin, a protein known to be present at Mt-organizing centers in other species and recently identified in plants as well. gamma-Tubulin antibody stained the cortical zone adjacent to the ventral wall, while little or no fluorescence was present elsewhere along the radial Mt array or at other sites in the cell. The antibody also stained the mitotic poles and phragmoplast in guard mother cells, as it does in other material. No staining was seen when the primary antibody was omitted. The results are consistent with nucleation of the radial array at a cortical-Mt-organizing zone next to the ventral wall, and set the stage for more in-depth studies on the spatial and temporal control of Mt formation in differentiating cells.
