Structure and size variations between 12A and 12D homoeologous chromosomes based on high-resolution cytogenetic map in allotetraploid cotton.
Article in Chromosoma, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 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
Cotton is a model system for studying polyploidization, genomic organization, and genome-size variation because the allotetraploid was formed 1-2 million years ago, which is old enough for sequence divergence but relatively recent to maintain genome stability. In spite of characterizing random genomic sequences in many polyploidy plants, the cytogenetic and sequence data that decipher homoeologous chromosomes are very limited in allopolyploid species. Here, we reported comprehensive analyses of integrated cytogenetic and linkage maps of homoeologous chromosomes 12A and 12D in allotetraploid cotton using fluorescence in situ hybridization and a large number of bacterial artificial chromosomes that were anchored by simple sequence repeat markers in the corresponding linkage maps. Integration of genetic loci into physical localizations showed considerable variation of genome organization, structure, and size between 12A and 12D homoeologous chromosomes. The distal regions of the chromosomes displayed relatively lower levels of structural and size variation than other regions of the chromosomes. The highest level of variation was found in the pericentric regions in the long arms of the two homoeologous chromosomes. The genome-size difference between A and D sub-genomes in allotetraploid cotton was mainly associated with uneven expansion or contraction between different regions of homoeologous chromosomes. As an attempt for studying on the polyploidy homoeologous chromosomes, these results are of general interest to the understanding and future sequencing of complex genomes in plant species.
