Organ-specific silencing of duplicated genes in a newly synthesized cotton allotetraploid.
Article in Genetics, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 103 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
Most eukaryotes have undergone genome doubling at least once during their evolutionary history. Hybridization followed by genome doubling (allopolyploidization) is a prominent mode of speciation in plants, leading to phenotypic novelty and changes in genome structure and gene expression. Molecular events that take place immediately after polyploid formation can be studied using newly synthesized allopolyploids. Here we studied the extent of gene silencing in a newly created and genomically stable allotetraploid cotton, of genotype AAGG, using an AFLP-cDNA display screen. Over 2000 transcripts were screened and approximately 5% of the duplicated genes in the allotetraploid were inferred to have been silenced or downregulated. Sequencing of 24 AFLP-cDNA fragments revealed genes with a variety of functions. Analysis by RT-PCR showed silencing or a strong expression bias toward one copy for 9 of 13 genes examined. Comparisons of expression patterns among eight organs in the allopolyploid showed that silencing and preferential expression are organ specific. Examination of silencing patterns in two other synthetic polyploids, of genotype AADD, showed that the same gene can be silenced independently in different genotypes. These results provide a detailed portrayal of gene silencing events that can occur following allopolyploidization and suggest epigenetic causal factors.
