Allopolyploidy is a peculiar process entailing the cohabitation of two (or more) divergent
genomes. Consequences on plant genomes are varied and can utlimately alter gene …

Gene expression dynamics is a key component of polyploid evolution, varying in nature,
intensity, and temporal scales, most particularly in allopolyploids, where two or more sub …

To study the consequences of hybridization and genome duplication on polyploid genome
evolution and adaptation, we used independently formed hybrids (Spartina× townsendii and …

In this study, we report the assembly and annotation of five reference transcriptomes for the
European hexaploid Spartina species (S. maritima, S. alterniflora and their homoploid …

Spartina species have a critical ecological role in salt marshes and represent an excellent
system to investigate recurrent polyploid speciation. Using the 454 GS-FLX pyrosequencer …

Gene and whole-genome duplications are widespread in plant nuclear genomes, resulting
in sequence heterogeneity. Identification of duplicated genes may be particularly …

Abstract Background The genus Spartina exhibits extensive hybridization and includes
classic examples of recent speciation by allopolyploidy. In the UK there are two hexaploid …

Spartina× townsendii arose during the end of the 19th century in England by hybridization
between the indigenous Spartina maritima and the introduced Spartina alterniflora, native to …

Allopolyploidy results from two events: the merger of divergent genomes and genome
duplication. Both events have important functional consequences for the evolution and …

Polyploidy and recurrent interspecific hybridization represent major features of Spartina
evolution, resulting in several superimposed divergent genomes that coexist in the currently …
