BraSto, a Stowaway MITE from Brassica: recently active copies preferentially accumulate in the gene space.
Article in Plant molecular biology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
We characterized a Brassica miniature inverted repeat transposable element (MITE) from the Stowaway superfamily, designated BraSto (Bra ssica Sto waway). BraSto copy number was assessed using real-time quantitative PCR in the two diploid species B. rapa (genome A) and B. oleracea (genome C) and the corresponding allotetraploid species B. napus (genome AC). Phylogenetic relationships among a set of 131 BraSto copies were then analyzed. BraSto appears to have been only moderately amplified in the Brassica genome and was still active recently with marks of proliferation in both diploid Brassica species, which diverged 3.75 million years ago, but also in the allotetraploid species after reuniting of the two differentiated genomes. We characterized insertion sites for low-divergence BraSto copies among the gene space of the B. rapa genome using bioinformatics approaches. For BraSto copies localized nearby or within genes, we observed frequent associations of BraSto with putative promoters and regulatory regions of genes, but exclusion from coding regions. In addition, BraSto was significantly similar to several Brassica expressed sequence tags (ESTs), including stress-induced ESTs. We also demonstrated the enrichment of BraSto sequences in binding sites for transcription factors and other regulatory elements. Our results lead to the question of a role for BraSto in the regulation of gene expression: this putative role, if further confirmed experimentally, would help to obtain a new insight into the significance of MITEs in the functional plant genome.
