Diploidization and genome size change in allopolyploids is associated with differential dynamics of low- and high-copy sequences
Summary Recent advances have highlighted the ubiquity of whole-genome duplication (polyploidy) in angiosperms, although subsequent genome size change and diploidization (returning to a diploid-like condition) are poorly ...
Parental transposable element loads influence their dynamics in young Nicotiana hybrids and allotetraploids.
(Wiley on behalf of New Phytologist Trust, 2019-02)
The genomic shock hypothesis suggests that allopolyploidy is associated with genome changes driven by transposable elements, as a response to imbalances between parental insertion loads. To explore this hypothesis, we ...
