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

The widespread occurrence of epigenetic alterations in allopolyploid species deserves scrutiny that DNA methylation systems may be perturbed by interspecies hybridization and polyploidization. Here we studied the genes involved in DNA methylation in Nicotiana tabacum (tobacco) allotetraploid containing S and T genomes inherited from Nicotiana sylvestris and Nicotiana tomentosiformis progenitors. To determine the inheritance of DNA methyltransferase genes and their expression patterns we examined three major DNA methyltransferase families (MET1, CMT3 and DRM) from tobacco and the progenitor species. Using Southern blot hybridization and PCR-based methods (genomic CAPS), we found that the parental loci of these gene families are retained in tobacco. Homoeologous expression was found in all tissues examined (leaf, root, flower) suggesting that DNA methyltransferase genes were probably not themselves targets of uniparental epigenetic silencing for over thousands of generations of allotetraploid evolution. The level of CG and CHG methylation of selected high-copy repeated sequences was similar and high in tobacco and its diploid progenitors. We speculate that natural selection might favor additive expression of parental DNA methyltransferase genes maintaining high levels of DNA methylation in tobacco, which has a repeat-rich heterochromatic genome.
