Mobilization of Stowaway-like MITEs in newly formed allohexaploid wheat species.
Article in Plant molecular biology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 29 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
Transposable elements (TEs) dominate the genetic capacity of most eukaryotes, especially plants, where they can account for up to 90 % of the genome, such as in wheat. The relationship between TEs and their hosts and the role of TEs in organismal biology are poorly understood. In this study, we have applied next generation sequencing, together with a transposon display technique in order to test whether a Stowaway-like MITE, termed Minos, transposes following allopolyploidization events in wheat. We have generated a 454-pyrosequencing database of Minos-specific amplicons (transposon display products) from a newly formed wheat allohexaploid and its parental lines and retrieved hundreds of novel MITE insertions in the allohexaploid. Clear mobilization of Minos was also seen by site-specific PCR analysis and sequence validation. In addition, using real-time qPCR analysis we observed an insignificant change in the relative quantity of Minos from the expected value of merging the two parental genomes, indicating that, despite its activation, no significant burst in Minos copy number can be seen in the newly formed allohexaploid. Interestingly, we found that CCGG sites surrounding Minos underwent massive hypermethylation following the allohexaploidization process. Our data suggest that MITEs have maintained their capacity for activity throughout the evolution of wheat and might be epigenetically deregulated in the first generations following allopolyploidization.
