Concerted genomic and epigenomic changes accompany stabilization of Arabidopsis allopolyploids
During evolution successful allopolyploids must overcome 'genome shock'between
hybridizing species but the underlying process remains elusive. Here, we report concerted …

Homoeolog-specific retention and use in allotetraploid Arabidopsis suecica depends on parent of origin and network partners
Background Allotetraploids carry pairs of diverged homoeologs for most genes. With the
genome doubled in size, the number of putative interactions is enormous. This poses …

Impact of natural genetic variation on the transcriptome of autotetraploid Arabidopsis thaliana
Polyploidy, the presence of more than two complete sets of chromosomes in an organism,
has significantly shaped the genomes of angiosperms during evolution. Two forms of …
