Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications.
Review in Journal of integrative plant biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Pentatricopeptide repeat (PPR) proteins constitute a large superfamily of nuclear-encoded proteins characterized by tandem helical repeats. They function as critical coordinators of nucleus-organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review summarizes recent advances in understanding the functional mechanisms of PPR proteins in major cereal and oilseed crops, with a focus on their roles in regulating seedling growth, stress responses, seed development, and cytoplasmic male sterility (CMS) restoration. We highlight how chloroplast-localized PPR proteins mediate RNA metabolism to ensure proper chloroplast biogenesis and seedling photosynthesis, while mitochondrial-targeted PPR proteins are crucial for RNA processing events that support respiration, embryo and endosperm development, and fertility restoration in CMS systems. We also describe how certain PPR proteins mediate biotic and abiotic stress responses through their functions in cold, drought, salt, and disease resistance, with specific members localized in chloroplasts or mitochondria. Finally, we outline unresolved questions regarding PPR protein complex assembly and environmental modulation, and highlight the emerging potential of engineered designer PPR (dPPR) proteins as programmable tools for precise RNA targeting and manipulation in organelles.
