Unraveling the sequence dynamics of the formation of genus-specific satellite DNAs in the family solanaceae.

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
Tandemly repeated DNAs, referred to as satellite DNAs, often occur in a genome in a genus-specific manner. However, the mechanisms for generation and evolution for these sequences are largely unknown because of the uncertain origins of the satellite DNAs. We found highly divergent genus-specific satellite DNAs that showed sequence similarity with genus-specific intergenic spacers (IGSs) in the family Solanaceae, which includes the genera Nicotiana, Solanum and Capsicum. The conserved position of the IGS between 25S and 18S rDNA facilitates comparison of IGS sequences across genera, even in the presence of very low sequence similarity. Sequence comparison of IGS may elucidate the procedure of the genesis of complex monomer units of the satellite DNAs. Within the IGS of Capsicum species, base substitutions and copy number variation of subrepeat monomers were causes of monomer divergence in IGS sequences. At the level of inter-generic IGS sequences of the family Solanaceae, however, genus-specific motif selection, motif shuffling between subrepeats and differential amplification among motifs were involved in formation of genus-specific IGS. Therefore, the genus-specific satellite DNAs in Solanaceae plants can be generated from differentially organized repeat monomers of the IGS rather than by accumulation of mutations from pre-existent satellite DNAs.
