Direct interaction between glyoxysomes and lipid bodies in cotyledons of the Arabidopsis thaliana ped1 mutant.
Article in Protoplasma, 2001. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 45 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
During germination and subsequent growth of fatty seeds, higher plants obtain energy from the glyconeogenic pathway in which fatty acids are converted to succinate in glyoxysomes, which contain enzymes for fatty acid beta-oxidation and the glyoxylate cycle. The Arabidopsis thaliana ped1 gene encodes a 3-ketoacyl-CoA thiolase (EC 2.3.1.16) involved in fatty acid beta-oxidation. The ped1 mutant shows normal germination and seedling growth under white light. However, etiolated cotyledons of the ped1 mutant grow poorly in the dark and have small cotyledons. To elucidate the mechanisms of lipid degradation during germination in the ped1 mutant, we examined the morphology of the ped1 mutant. The glyoxysomes in etiolated cotyledons of the ped1 mutant appeared abnormal, having tubular structures that contained many vesicles. Electron microscopic analysis revealed that the tubular structures in glyoxysomes are derived from invagination of the glyoxysomal membrane. By immunoelectron microscopic analysis, acyl-CoA synthetase (EC 6.2.1.3), which was located on the membrane of glyoxysomes in wild-type plants, was located on the membranes of the tubular structures in the glyoxysomes in the ped1 mutant. These invagination sites were always in contact with lipid bodies. The tubular structure had many vesicles containing substances with the same electron density as those in the lipid bodies. From these results, we propose a model in which there is a direct mechanism of transporting lipids from the lipid bodies to glyoxysomes during fatty acid beta-oxidation.
