The central cell nuclear position at the micropylar end is maintained by the balance of F-actin dynamics, but dispensable for karyogamy in Arabidopsis.

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 messageAdvances in Fertilization. In flowering plants, fertilization is initiated by the delivery of immotile sperm cells to the boundary between two female gametes, the egg cell and the central cell. During female gamete development in Arabidopsis, the nucleus of the central cell becomes positioned toward this boundary. How this specific polarized nuclear position is maintained is unclear and whether it plays a role in successful fertilization remains to be determined. By disrupting and manipulating F-actin dynamics in the central cell, we identified that the balance of F-actin dynamics is important for nuclear positioning in the central cell and that the presence of intact F-actin cables in the central cell correlates with successful karyogamy regardless of the central cell nuclear position. We also report that the surface of the central cell nucleus is enriched in F-actin. Thus, the central cell nucleus might also serve as a site that organizes F-actin cytoskeleton to promote sperm cell nucleus movement and karyogamy.
