Interspecific hybridization leads to new interactions among divergent genomes, revealing
the nature of genetic incompatibilities having accumulated during and after the origin of …

The maintenance of species integrity despite pervasive hybridization is ruled by the interplay
between reproductive barriers. Endogenous postzygotic isolation will shape the patterns of …

Background How new forms arise in nature has engaged evolutionary biologists since
Darwin's seminal treatise on the origin of species. Transposable elements (TEs) may be …

Transposable elements (TE s) are expectedly central to genome evolution. To assess the
impact of TE s in driving genome turnover, we used allopolyploid genomes, showing …

Wheat has one of the largest and most repetitive genomes among major crop plants,
containing over 85% transposable elements (TEs). TEs populate genomes much in the way …

Abstract Background Transposable elements (TEs) are a rapidly evolving fraction of the
eukaryotic genomes and the main contributors to genome plasticity and divergence …

Following allopolyploidization, nascent polyploid wheat species react with massive genomic
rearrangements, including deletion of transposable element-containing sequences. While …

It is becoming increasingly evident that interspecific hybridization at the homoploid level or
coupled with whole-genome duplication (ie allopolyploidization) has played a major role in …

Reciprocal exchanges of DNA (crossovers) that occur during meiosis are mandatory to
ensure the production of fertile gametes in sexually reproducing species. They also …

One of the most striking patterns of genome structure is the tight, typically negative,
association between transposable elements (TEs) and meiotic recombination rates. While …
