In situ architecture of the nuclear pore complex of the higher plant Arabidopsis thaliana.
Article in Nature plants, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The nucleus is enclosed by the nuclear envelope, which contains nuclear pore complexes (NPCs). While NPCs have been well studied in vertebrates, yeast and algae, in situ structural data for higher plants is lacking. Here we show that individual nucleoporins of Arabidopsis thaliana and humans exhibit high structural similarity. We report an in situ NPC structure of higher plants, derived from A. thaliana root protoplasts using cryo-electron tomography, subtomogram averaging and homology-based integrative modelling. We present the AtNPC model based on predictions of A. thaliana nucleoporins (NUPs), supported by mass spectrometry. Here the AtNPC scaffold contains one Y-complex ring at the cytosolic and two at the nuclear ring. The AtNPC contains prominent NUP155 connector elements that are conserved in human NPCs but not in Chlamydomonas reinhardtii NPCs. Our model suggests that the ELYS homologue HOS1 plays an important role in the head-to-tail connection of Y-complexes in AtNPCs.
