Multiple-copy cluster-type organization and evolution of genes encoding O-methyltransferases in the apple.
Article in Genetics, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Plant O-methyltransferases (OMTs) play important roles in secondary metabolism. Two clusters of genes coding for caffeic acid OMT (COMT) have been identified in the apple genome. Three genes from one cluster and two genes from another cluster were isolated. These five genes encoding COMT, designated Mdomt1-Mdomt5 (GenBank accession nos. DQ886018-DQ886022), were distinguished by a (CT)(n) microsatellite in the 5'-UTR and two transposon-like sequences present in the promoter region and intron 1, respectively. The transposon-like sequence in intron 1 unambiguously traced the five Mdomt genes in the apple to a common ancestor. The ancestor must have undergone an initial duplication generating two progenitors, and this was followed by further duplication of these progenitors resulting in the two clusters identified in this study. The distal regions of the transposon-like sequences in promoter regions of Mdomt genes are capable of forming palindromic hairpin-like structures. The hairpin formation is likely responsible for nucleotide sequence differences observed in the promoter regions of these genes as it plays a destabilizing role in eukaryotic chromosomes. In addition, the possible mechanism of amplification of Mdomt genes in the apple genome is also discussed.
