Actin filament organization and polarity in pollen tubes revealed by myosin II subfragment 1 decoration.

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 actin cytoskeleton plays a crucial role in pollen tube growth. In elongating pollen tubes the organization and arrangement of actin filaments (AFs) differs between the shank and apical region. However, the orientation of AFs in pollen tubes has not yet been successfully demonstrated. In the present work we have used myosin II subfragment 1 (S1) decoration to determine the polarity of AFs in pollen tubes. Electron microscopy studies revealed that in the shank of the tube bundles of AFs exhibit uniform polarity with those close to the cell cortex having their barbed ends oriented towards the tip of the pollen tube while those in the cell center have their barbed ends oriented toward the base of the tube. At the subapex, some AFs are organized in closely packed and longitudinally oriented bundles and some form curved bundles adjacent to the cell membrane. In contrast, few AFs are dispersed with random orientation in the extreme apex of the pollen tube. Our results confirm that the direction of cytoplasmic streaming within pollen tubes is determined by the polarity of AFs in the bundles.
