TL;DR: The genome sequence of segmental allotetraploid peanut is reported and suggests that diversity generated by genetic deletions and homeologous recombination helped to favor the domestication of Arachis hypogaea over its diploid relatives.

TL;DR: It was found that artificial demethylation had little or no effect on apospory, whereas it induced a significant depression of parthenogenesis, which suggested that factors controlling repression of Parthenogenesis might be inactivated in apomictic Paspalum by DNA methylation.

TL;DR: The representation and chromosome distribution of ALI in peanut was almost additive of those of the parental species suggesting that the spontaneous hybridization of the two parental species of peanut followed by chromosome doubling would not have induced a significant burst of ALi transposition.

TL;DR: The constancy of the Cx values observed in the polyploids compared to those of the parental species suggests that the allopolyploidization event that originated the cultivated peanut did not induce significant changes in the genome size.

TL;DR: The participation of satDNA sequences in the karyotype diversification of wild diploid Arachis species can be explained, at least in part, by the differential representation of ATR-2 among the different species or even among the chromosomes of the same complement.
