Differential impact of retrotransposon populations on the genome of allotetraploid tobacco (Nicotiana tabacum).

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
LTR-retrotransposons contribute substantially to the structural diversity of plant genomes. Recent models of genome evolution suggest that retrotransposon amplification is offset by removal of retrotransposon sequences, leading to a turnover of retrotransposon populations. While bursts of amplification have been documented, it is not known whether removal of retrotransposon sequences occurs continuously, or is triggered by specific stimuli over short evolutionary periods. In this work, we have characterized the evolutionary dynamics of four populations of copia-type retrotransposons in allotetraploid tobacco (Nicotiana tabacum) and its two diploid progenitors Nicotiana sylvestris and Nicotiana tomentosiformis. We have used SSAP (Sequence-Specific Amplification Polymorphism) to evaluate the contribution retrotransposons have made to the diversity of tobacco and its diploid progenitor species, to quantify the contribution each diploid progenitor has made to tobacco's retrotransposon populations, and to estimate losses or amplifications of retrotransposon sequences subsequent to tobacco's formation. Our results show that the tobacco genome derives from a turnover of retrotransposon sequences with removals concomitant with new insertions. We have detected unique behaviour specific to each retrotransposon population, with differences likely reflecting distinct evolutionary histories and activities of particular elements. Our results indicate that the retrotransposon content of a given plant species is strongly influenced by the host evolutionary history, with periods of rapid turnover of retrotransposon sequences stimulated by allopolyploidy.
