1 · What the graph read from it

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.

2 · The registry

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

Plants being sessile organisms exhibit unique features in ribosomes, which might aid in rapid gene expression and regulation in response to varying environmental conditions. Here, we present high-resolution structures of the 60S and 80S ribosomes from wheat, a monocot staple crop plant (Triticum aestivum). While plant ribosomes have unique plant-specific rRNA modification (Cm1847) in the peptide exit tunnel (PET), the zinc-finger motif in eL34 is absent, and uL4 is extended, making an exclusive interaction network. We note differences in the eL15-helix 11 (25S) interaction, eL6-ES7 assembly, and certain rRNA chemical modifications between monocot and dicot ribosomes. In eukaryotes, we observe highly conserved rRNA modification (Gm75) in 5.8S rRNA and a flipped base (G1506) in PET. These features are likely involved in sensing or stabilizing nascent chain. Finally, we discuss the importance of the universal conservation of three consecutive rRNA modifications in all ribosomes for their interaction with A-site aminoacyl-tRNA.
