Effects of inefficient transcription termination of rbcL on the expression of accD in plastids of 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
The plastid accD gene encodes one subunit of a multimeric acetyl-CoA carboxylase that is required for fatty acid biosynthesis. In Arabidopsis thaliana, the accD gene is transcribed by the nuclear-encoded phage-type RNA polymerase, and the accumulation of accD transcripts is subjected to a dynamic pattern during chloroplast development. However, the mechanisms underlying the regulation of accD expression remain unknown. Here, we showed that the inefficient transcription termination of rbcL due to the absence of RHON1 impaired the developmental profile of accD, resulting in the constitutive expression of accD during chloroplast development. Moreover, the accumulation of accD transcripts accordingly resulted in an increase in accD protein levels, suggesting that transcript abundance is critical for accD gene production. Our study demonstrates that the interplay between accD and upstream rbcL regulates the expression of accD and highlights the significance of transcriptional regulation in plastid gene expression in higher plants.
