A novel connection between nucleotide and carbohydrate metabolism in mitochondria: sugar regulation of the Arabidopsis nucleoside diphosphate kinase 3a gene.
Article in Plant cell reports, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 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
Sugar metabolism is intricately connected with mitochondria through the conversion of sugars to ATP, and through the production of carbon skeletons that can be used in anabolic processes. Sugar molecules also take part in signalling cascades. In this study we investigated the impact of sucrose on the expression of the Arabidopsis thaliana Nucleoside Diphosphate Kinase gene family (NDPK, EC 2.7.4.6), focusing on NDPK3a, the product of which is located predominantly in mitochondria. Using quantitative PCR we show that the NDPK3a gene is subject to sucrose and glucose induction, while no other Arabidopsis NDPK gene are sucrose-inducible. The induction reaches a half-maximum after about 6 hours and is stable for at least 48 h. Sucrose and glucose inductions were found not to be affected by the presence of a hexokinase inhibitor, N-acetyl-glucosamine. Furthermore, turanose, a sucrose analogue that is not metabolised in plant cells, did not induce NDPK3a gene expression. An analysis of the NDPK3a gene revealed two WBOXHWISO1 boxes in the promoter region, elements that have previously been reported to be involved in sugar signalling in barley via the SUSIBA2 protein. SUSIBA2 belongs to the WRKY group of transcription factors. In this study we used two mutants containing T-DNA insertions in WRKY-genes, AtWrky4 and AtWrky34, to investigate the possible involvement of WRKY transcription factors in the sugar induction of NDPK3a.
