A potential role for protein O-fucosylation during pollen-pistil interactions.
Article in Plant signaling & behavior, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Putative protein O-fucosyltransferases (POFTs) represent a large family of Glycosyl Transferase family 65 domain-containing proteins in land plants, with at least 39 proposed members in the Arabidopsis thaliana genome alone. We recently identified a member of this family, AtOFT1 (At3g05320), in which loss-of-function mutants display impaired sexual reproduction that was linked to a defective male gamete. Specifically, oft1 mutant pollen tubes are ineffective at penetrating the stigma-style interface leading to a drastic reduction in seed set and a nearly 2000-fold reduction in pollen transmission. Our findings establish that AtOFT1 plays a critical role in pollen tube penetration through the stigma/style in Arabidopsis and further suggest an important role for protein O-glycosylation events that potentially influence pollen tube mechanical strength or the ability to respond to positional guidance cues during the process of tube growth and fertilization.
