Missing steps of mitochondrial translation initiation identified in plants.
Article in bioRxiv : the preprint server for biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Translation initiation, the first step of the translation cycle, involves initiation factors (mtIF) 2 and 3 in mitochondria. mtIF3 release from the ribosomal small subunit was believed to be a prerequisite for the recruitment of the initiator tRNA. Here we use cryogenic electron microscopy to characterize plant mitochondria pre-initiation complexes and to reveal how plant mtIF3 binds the initiator tRNA and facilitates its accommodation in the decoding center.
