Identification and characterization of a new member of the SINE Au retroposon family (GmAu1) in the soybean, Glycine max (L.) Merr., genome and its potential application.
Article in Plant cell reports, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
A plant short interspersed element (SINE) was identified in Glycine max after re-sequencing of the soybean sequence characterized amplified region (SCAR) markers. Detailed analysis revealed that this newly recognized SINE element consisted of a tRNA-related region, a tRNA non-related region, direct flanking repeat sequences, and a short stretch of Ts at the 3'-terminal region. These features are similar to previously characterized SINEs. To investigate the evolution of the SINE retroposon, BLASTN was used to search against genome sequences of other plants. Since it is homologous with the retroposon Au in Aegilops umbellulata (wheat) and its homology in soybean, the SINE is named as GmAu1. Genome analysis of the Glycine max var. Willimas 82 uncovered more than 847 copies of GmAu1 per haploid genome of soybean. Examination of the regions flanking the inserted GmAu1 sequences indicated a preference for introns over exons or other noncoding regions. Considering the flanking insertion sequences, 146 primers were designed in order to detect insertion mutations by a PCR-based method. Seventy-seven primers displayed polymorphism and were used to develop corresponding GmAu1-based SCAR markers. The retroposon GmAu1 and its related SCAR markers identified in this study will prove valuable to future investigations into the genetic mapping, phylogeny, and evolution of the Glycine genus.
