Molecular and chromosomal evidence for allopolyploidy in soybean.
Article in Plant physiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 85 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
Recent studies have documented that the soybean (Glycine max) genome has undergone two rounds of large-scale genome and/or segmental duplication. To shed light on the timing and nature of these duplication events, we characterized and analyzed two subfamilies of high-copy centromeric satellite repeats, CentGm-1 and CentGm-2, using a combination of computational and molecular cytogenetic approaches. These two subfamilies of satellite repeats mark distinct subsets of soybean centromeres and, in at least one case, a pair of homologs, suggesting their origins from an allopolyploid event. The satellite monomers of each subfamily are arranged in large tandem arrays, and intermingled monomers of the two subfamilies were not detected by fluorescence in situ hybridization on extended DNA fibers nor at the sequence level. This indicates that there has been little recombination and homogenization of satellite DNA between these two sets of centromeres. These satellite repeats are also present in Glycine soja, the proposed wild progenitor of soybean, but could not be detected in any other relatives of soybean examined in this study, suggesting the rapid divergence of the centromeric satellite DNA within the Glycine genus. Together, these observations provide direct evidence, at molecular and chromosomal levels, in support of the hypothesis that the soybean genome has experienced a recent allopolyploidization event.
