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 genes rbcS and rbcL encode, respectively, the small and large subunits of the photosynthetic carbon dioxide fixation enzyme ribulose bisphosphate carboxylase/oxygenase. There is a single rbcL gene in each chloroplast chromosome; a family of rbcS genes is located in the nuclear genome. These two genes are not expressed in mesophyll cells but are in adjacent bundle-sheath cells of leaves of the C4 plant Zea mays. Two regions of the maize gene rbcS-m3 are required for suppressing expression in mesophyll cells. One region is just beyond the translation termination site in the 3' region, and the other is several hundred base pairs upstream of the transcription start site. A binding site for a protein with limited homology to the viral, yeast, and mammalian transcription repressor-activator YY1 (Yin-Yang I), has now been identified in the 3' region. A maize gene for a protein with zinc fingers homologous to those of YY1 has been isolated, characterized, and expressed in Escherichia coli. The gene is designated trm1 (transcription repressor-maize 1). The protein TRM1 binds to the YY1-like site and, in addition, TRM1 binds to two sequence regions in the 5' region of the gene that have no homology to the YY1 site. Mutagenesis or deletion of any of these three sequences eliminates repression of rbcS-m3 reporter genes in mesophyll cells.
