Polyspermy produces tri-parental seeds in maize.
Article in Current biology : CB, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 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
In flowering plants, two pairs of gametes participate in double fertilization. One of the two sperm delivered by the pollen tube (PT) fuses with the egg cell to form the zygote, whereas the second unites with the central cell to produce the endosperm [1]. Most animal species prevent polyspermy through a transient, fast block established by the depolarization of the egg membrane within milliseconds after encountering the first sperm, followed by a slow block generated through enzymatic changes in the extracellular matrix surrounding the egg [2]. Although in vitro fertilization experiments suggest that the maize zygote starts cell wall deposition within 30 seconds after fusion with a sperm [3], thereby preventing further fertilization events, it is unknown whether plant gametes prevent polyspermy by a fast block. Here, using a genetic approach, the absence of a fast block preventing polyspermy in the maize central cell is demonstrated. A putative polyspermy event involving the egg indicates the existence of tri-parental individuals, which may provide an alternative route to polyploidy, distinct from the one involving unreduced gametes.
