The 'apparently'simple genomes of many angiosperms mask complex evolutionary histories.
The reference genome sequence for cotton (Gossypium spp.) revealed a ploidy change of a
complexity unprecedented to date, indeed that could not be distinguished as to its exact
dosage. Herein, by developing several comparative, computational and statistical
approaches, we revealed a 5× multiplication in the cotton lineage of an ancestral genome
common to cotton and cacao, and proposed evolutionary models to show how such a …
