1 · What the graph read from it

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.

2 · The registry

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 gene rbcL encodes the large subunit of the CO(2)-fixing enzyme ribulose-bisphosphate carboxylase. In previous work a target for photo-accelerated degradation of Chlamydomonas reinhardtii rbcL transcripts in vivo was found to lie within the first 63 nucleotides, and a sequence element required for increasing the longevity of transcripts of rbcL-reporter genes was found to occur between nucleotides 170 and 350. Photo-accelerated degradation of rbcL transcripts has been found to require nucleotides 21 to 41. Transcript nucleotides lying between 329 and 334 and between 14 and 27 are essential for stabilizing transcripts in vivo; mutations in either region reduce the longevity of transcripts. It is postulated that the effectiveness of photo-accelerated endonuclease attacks on the nucleotide 21 to 41 region is reduced by physical blockage or distortion of the target sequence by interacting proteins that associate with nucleotides in the 14 to 27 and 329 to 334 regions of the transcripts. Both the nucleotide +329 to +334 stabilizing sequence of rbcL and a transcription enhancing sequence that lies between +126 and +170 encode well conserved (cyanobacteria through angiosperms) amino acid sequences; the evolution of expression control elements within the protein coding sequence of rbcL is considered.
