Solid-like condensation of MORF8 inhibits RNA editing under heat stress in Arabidopsis.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Heat stress inhibits photosynthesis efficiency, thereby suppressing plant growth and crop yield. However, the mechanism underlying this inhibition is not fully understood. Here, we report that the multiple organellar RNA-editing factor 8 (MORF8) forms condensates with solid-like properties in chloroplasts upon heat stress. In vitro data show that the MORF8 condensation is intrinsically heat-dependent and primarily determined by its IDR (intrinsically disordered region). Purification and characterization of MORF8 condensates show that numerous editing factors including PPR proteins and MORFs are partitioned. We provide both genetic and biochemical evidence that MORF8 condensation inhibits chloroplast RNA editing. In agreement, we find that both heat stress and MORF8 condensation lead to reduced editing of RNAs encoding NADH dehydrogenase-like (NDH) complex and impaired NDH activity and photosynthesis efficiency. These findings uncover MORF8 as a putative chloroplastic thermosensor that mediates photosynthesis inhibition by heat and highlight the functional significance of solid material properties of biomolecular condensates.
