Nuclear membrane localization during pollen development and apex-focused polarity establishment of SYP124/125 during pollen germination in Arabidopsis thaliana.
Article in Plant reproduction, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
key messageEstablishment of apex-polarity. Elongation of the pollen tube is a highly coordinated process involving polarized secretion of cell wall and membrane materials to the apical region. We investigated changes in the localization of soluble NSF attachment proteins (SNAREs) in developing pollen grains and the pollen tube for transgenic Arabidopsis expressing pollen-specific plasma-membrane Qa-SNAREs (SYP124, 125 and 131) fused with the green fluorescent protein (GFP). The expression of SYP124 and SYP125 was firstly detected in the microspore nuclear membrane during pollen mitosis II. Although SYP124, 125 and 131 accumulated throughout the cytosol in the mature pollen grain, GFP-SYP124 and GFP-SYP125 were highly concentrated in the apical or subapical regions of the elongating pollen tube with slightly different localization patterns, whereas GFP-SYP131 was uniformly localized to the plasma membrane of the pollen tube. The apex-focused polarity of GFP-SYP125 was established coincident with formation of a Ca(2+) gradient before pollen germination. These results suggest that SNAREs function differentially in the same cells and that at least two distinct membrane transport pathways are involved in the pollen development and the pollen tube germination and elongation.
