1 · What the graph read from it

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.

2 · The registry

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

Although maize (Zea mays) retrotransposons are recombinationally inert, the highly polymorphic structure of maize haplotypes raises questions regarding the local effect of intergenic retrotransposons on recombination. To examine this effect, we compared recombination in the same genetic interval with and without a large retrotransposon cluster. We used three different bz1 locus haplotypes, McC, B73, and W22, in the same genetic background. We analyzed recombination between the bz1 and stc1 markers in heterozygotes that differ by the presence and absence of a 26-kb intergenic retrotransposon cluster. To facilitate the genetic screen, we used Ds and Ac markers that allowed us to identify recombinants by their seed pigmentation. We sequenced 239 recombination junctions and assigned them to a single nucleotide polymorphism-delimited interval in the region. The genetic distance between the markers was twofold smaller in the presence of the retrotransposon cluster. The reduction was seen in bz1 and stc1, but no recombination occurred in the highly polymorphic intergenic region of either heterozygote. Recombination within genes shuffled flanking retrotransposon clusters, creating new chimeric haplotypes and either contracting or expanding the physical distance between markers. Our findings imply that haplotype structure will profoundly affect the correlation between genetic and physical distance for the same interval in maize.
