Mutation of the pentatricopeptide repeat-SMR protein SVR7 impairs accumulation and translation of chloroplast ATP synthase subunits in Arabidopsis thaliana.

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
RNA processing, RNA editing, RNA splicing and translational activation of RNAs are essential post-transcriptional steps in chloroplast gene expression. Typically, the factors mediating those processes are nuclear encoded and post-translationally imported into the chloroplasts. In land plants, members of the large pentatricopeptide repeat (PPR) protein family are required for individual steps in chloroplast RNA processing. Interestingly, a subgroup of PPR proteins carries a C-terminal small MutS related (SMR) domain. Here we analyzed the consequences of mutations in the SVR7 gene, which encodes a PPR-SMR protein, in Arabidopsis thaliana. We demonstrate that SVR7 mutations lead to a specific reduction in chloroplast ATP synthase levels. Furthermore, we found aberrant transcript patterns for ATP synthase coding mRNAs in svr7 mutants. Finally, a reduced ribosome association of atpB/E and rbcL mRNAs in svr7 mutants suggests the involvement of the PPR-SMR protein SVR7 in translational activation of these mRNAs. We describe that the function of SVR7 in translation has expanded relative to its maize ortholog ATP4. The results provide evidence for a relaxed functional conservation of this PPR-SMR protein in eudicotyledonous and monocotyledonous plants, thus adding to the knowledge about the function and evolution of PPR-SMR proteins.
