Site specific cytosine methylation in rice nonautonomous transposable element nDart.
Article in Plant molecular biology, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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 mobile nonautonomous element nDart, which is active in intact rice plants, exhibits locus specific transposition. Due to the high homogeneity of nDart elements, the locus specificity of nDart transposition might be controlled by factors other than genetic differences. In this study, we elucidated the regulation of the locus specificity of nDart transposition. The difference of transpositional activities in 10 nDart elements among rice varieties exhibiting nDart transposition was clearly correlated with the methylation state of nDart elements. Both hyper- and hypo-methylated nDart elements were inactive, while site specific methylation in both subterminal regions was identified in active nDart loci. The specific methylation sites contain the pentamer motif GCC/ACG. The repeated motifs in the subterminal region of nDart elements may contribute to the stable secondary structure of nDart elements with low free energy. Our results suggested that site specific cytosine methylation may loosen the stable secondary structure of the nDart element to allow it to bind TPase, which then perform the excision of nDart elements from genomic loci.
