Comparative inference of illegitimate recombination between rice and sorghum duplicated genes produced by polyploidization.
Article in Genome research, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 47 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
Whole-genome duplication produces massive duplicated blocks in plant genomes. Sharing appreciable sequence similarity, duplicated blocks may have been affected by illegitimate recombination. However, large-scale evaluation of illegitimate recombination in plant genomes has not been possible previously. Here, based on comparative and phylogenetic analysis of the sequenced genomes of rice and sorghum, we report evidence of extensive and long-lasting recombination between duplicated blocks. We estimated that at least 5.5% and 4.1% of rice and sorghum duplicated genes have been affected by nonreciprocal recombination (gene conversion) over nearly their full length after rice-sorghum divergence, while even more (8.7% and 8.1%, respectively) have been converted over portions of their length. We found that conversion occurs in higher frequency toward the terminal regions of chromosomes, and expression patterns of converted genes are more positively correlated than nonconverted ones. Though converted paralogs are more similar to one another than nonconverted ones, elevated nucleotide differences between rice-sorghum orthologs indicates that they have evolved at a faster rate, implying that recombination acts as an accelerating, rather than a conservative, element. The converted genes show no change in selection pressure. We also found no evidence that conversion contributed to guanine-cytosine (GC) content elevation.
