WHITE PANICLE1, a Val-tRNA Synthetase Regulating Chloroplast Ribosome Biogenesis in Rice, Is Essential for Early Chloroplast Development.

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
Chloroplasts and mitochondria contain their own genomes and transcriptional and translational systems. Establishing these genetic systems is essential for plant growth and development. Here we characterized a mutant form of a Val-tRNA synthetase (OsValRS2) from Oryza sativa that is targeted to both chloroplasts and mitochondria. A single base change in OsValRS2 caused virescent to albino phenotypes in seedlings and white panicles at heading. We therefore named this mutant white panicle 1 (wp1). Chlorophyll autofluorescence observations and transmission electron microscopy analyses indicated that wp1 mutants are defective in early chloroplast development. RNA-seq analysis revealed that expression of nuclear-encoded photosynthetic genes is significantly repressed, while expression of many chloroplast-encoded genes also changed significantly in wp1 mutants. Western-blot analyses of chloroplast-encoded proteins showed that chloroplast protein levels were reduced in wp1 mutants, although mRNA levels of some genes were higher in wp1 than in wild type. We found that wp1 was impaired in chloroplast ribosome biogenesis. Taken together, our results show that OsValRS2 plays an essential role in chloroplast development and regulating chloroplast ribosome biogenesis.
