Translation of partially overlapping psbD-psbC mRNAs in chloroplasts: the role of 5'-processing and translational coupling.

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 chloroplast psbD and psbC genes encode the D2 and CP43 proteins of the photosystem II complex, and they are generally cotranscribed. We report studies on the basic translation process of tobacco psbD-psbC mRNAs using an in vitro translation system from tobacco chloroplasts. The primary transcript has an unusually long 5'-UTR (905 nt). We show that it is translatable. Processing of the 5'-UTR greatly enhances the translation efficiency of the psbD cistron. A striking feature is that psbD and psbC cistrons overlap by 14 nt. Removal of the psbD 5'-UTR plus the start codon and introduction of a premature termination codon in the psbD cistron considerably reduce the translation efficiency of the downstream psbC cistron. These results indicate that translation of the psbC cistron depends largely on that of the upstream psbD cistron and thus shows translational coupling; however, a portion is independently translated. These observations, together with the presence of monocistronic psbC mRNAs, suggest that the psbD and psbC cistrons are translated via multiple processes to produce necessary amounts of D2 and CP43 proteins.
