Antisense repression of the chloroplast triose phosphate translocator affects carbon partitioning in transgenic potato plants.
Article in Proceedings of the National Academy of Sciences of the United States of America, 1993. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 37 papers.
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 major chloroplast envelope membrane protein E29 is central for the communication between chloroplasts and cytosol. It has been identified as the triose phosphate translocator (TPT) exporting the primary products of the Calvin cycle (i.e., triose phosphates and 3-phosphoglycerate) out of the chloroplast in a strict counter exchange for Pi. To study the in vivo role of the TPT, transgenic potato plants were constructed that have a reduced expression of the TPT at both the RNA and protein level due to antisense inhibition. Chloroplasts isolated from these plants show a 20-30% reduction with respect to their ability to import Pi. The reduced TPT activity leads to a reduction of maximal photosynthesis by 40-60%, to a change in carbon partitioning into starch at the expense of sucrose and amino acids, and to an increase of the leaf starch content by a factor of approximately 3. At early developmental stages the inhibited plants are retarded in growth compared to the wild type.
