Regulatory sequences of orthologous petD chloroplast mRNAs are highly specific among Chlamydomonas species.

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 5' untranslated regions (UTR) of chloroplast mRNAs often contain regulatory sequences that control RNA stability and/or translation. The petD chloroplast mRNA in Chlamydomonas reinhardtii has three such essential regulatory elements in its 362-nt long 5' UTR. To further analyze these elements, we compared 5' UTR sequences from four Chlamydomonas species (C. reinhardtii, C. incerta, C. moewusii and C. eugametos) and five independent strains of C. reinhardtii. Overall, these petD 5' UTRs have relatively low sequence conservation across these species. In contrast, sequences of the three regulatory elements and their relative positions appear partially conserved. Functionality of the 5' UTRs was tested in C. reinhardtii chloroplasts using beta-glucuronidase reporter genes, and the nearly identical C. incerta petD functioned for mRNA stability and translation in C. reinhardtii chloroplasts while the more divergent C. eugametos petD did not. This identified what may be key features in these elements. We conclude that these petD regulatory elements, and possibly the corresponding trans-acting factors, function via mechanisms highly specific and surprisingly sensitive to minor sequence changes. This provides a new and broader perspective of these important regulatory sequences that affect photosynthesis in these algae.
