Dynamics of mobile element activity in chalcone synthase loci in the common morning glory (Ipomoea purpurea).

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
Mobile element dynamics in seven alleles of the chalcone synthase D locus (CHS-D) of the common morning glory (Ipomoea purpurea) are analyzed in the context of synonymous nucleotide sequence distances for CHS-D exons. By using a nucleotide sequence of CHS-D from the sister species Ipomoea nil (Japanese morning glory [Johzuka-Hisatomi, Y., Hoshino, A., Mori, T., Habu, Y. & Iida, S. (1999) Genes Genet. Syst. 74, 141-147], it is also possible to determine the relative frequency of insertion and loss of elements within the CHS-D locus between these two species. At least four different types of transposable elements exist upstream of the coding region, or within the single intron of the CHS-D locus in I. purpurea. There are three distinct families of miniature inverted-repeat transposable elements (MITES), and some recent transpositions of Activator/Dissociation (Ac/Ds)-like elements (Tip100), of some short interspersed repetitive elements (SINEs), and of an insertion sequence (InsIpCHSD) found in the neighborhood of this locus. The data provide no compelling evidence of the transposition of the mites since the separation of I. nil and I. purpurea roughly 8 million years ago. Finally, it is shown that the number and frequency of mobile elements are highly heterogeneous among different duplicate CHS loci, suggesting that the dynamics observed at CHS-D are locus-specific.
