Macrotransposition and other complex chromosomal restructuring in maize by closely linked transposons in direct orientation.
Article in The Plant cell, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 27 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
Several observations indicate that compatible ends of separate, yet closely linked, transposable elements (TEs) can interact in alternative transposition reactions. First, pairs of TEs cause chromosome breaks with frequencies inversely related to the intertransposon distance. Second, some combinations of two TEs produce complex rearrangements that often include DNA adjacent to one or both elements. In pairs of TEs in direct orientation, alternative reactions involving the external ends of the two TEs should lead to the transposition of a macrotransposon consisting of both elements plus the intervening chromosomal segment. Such macrotransposons have been hypothesized previously based on deletions, but no macrotransposon insertions have been recovered. To detect macrotransposition, we have analyzed heritable chromosomal rearrangements produced by a chromosome-breaking pair of Ac and Ds elements situated 6.5 kb apart in direct orientation in a part of the maize (Zea mays) genome dispensable for viability. Here, we show that the postulated macrotransposon can excise and reinsert elsewhere in the genome. In addition, this transposon pair produces other complex rearrangements, including deletions, inversions, and reshuffling of the intertransposon segment. Thus, closely linked TE pairs, a common transposition outcome in some superfamilies, are adept at restructuring chromosomes and may have been instrumental in reshaping plant genomes.
