A novel translocation event leads to a recombinant stable chromosome with interrupted centromeric domains in rice.
Article in Chromosoma, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Rice (Oryza sativa L.) centromeres are composed of 155-bp satellite repeats (CentO), centromere-specific retrotransposon (CRR), and a variety of other repeats. Previous studies have shown that CentO and CRR elements are both parts of the functional centromere/kinetochore complex. In this study, a naturally occurring karyotype rearrangement involving a reciprocal translocation between chromosomes 9 and 11 in an indica rice Zhongxian 3037 has been identified. The recombinant centromere in Chr11L·9L has two CentO tandem arrays, separated by a long array of 5S rDNAs. Chromatin immunoprecipitation and immunostaining showed that centromere-specific histone H3 (cenH3) variant was bound to the two flanking CentO arrays, but not to the 5S rDNAs residing between the CentO repeats. No obvious difference was detected in H3K4me2 and H3K9ac modification of the 5S rDNAs between the wild type and the mutant. Therefore, the translocation results in a recombinant stable chromosome with interrupted centromeric domains. A lack of cenH3 binding in 5S rDNA sequences residing within the centromeric core suggests that not all centromeric sequences confer centromere identity in rice.
