Introgression of the chromosomal region with the Pi-cd locus from Oryza meridionalis into O. sativa L. during rice domestication.
Article in TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
key messageThe genotype of the Pi-cd locus found in blast-resistant rice variety Kitakurin, which is a cultivated rice from Japan belonging to Oryza sativa japonica, is identical to that of its wild relative O. meridionalis. Crop domestication from wild relatives to cultivated species has encompassed significant phenotypic changes. However, little is known about the genetic changes involved in domestication. Here, we surveyed the origin of the Pi-cd locus across Oryza species with AA genomes by comparison with the genome sequences of Hoshinoyume (HS), which does not carry the Pi-cd blast resistance gene, and Kitakurin (KK), which carries the Pi-cd blast resistance gene. We found that variety-specific transposons were enriched at the Pi-cd locus. The genotype of the Pi-cd locus characterized by transposons in HS and KK was specific to each Oryza species with the AA genome. The Kitaake (KT) genotype at the Pi-cd locus found in KK was identical only to that of O. meridionalis and distributed only in subgroups of japonica in the World Rice Collection and tropical japonica in the Japanese Rice Collection, whereas it was not present in O. rufipogon accessions. The distinct distributions of genotypes of the Pi-cd locus clearly demonstrated that the Pi-cd locus was introgressed from O. meridionalis into O. sativa, specific to tropical japonica.
