Repeated sequences and polyploidy play a central role in plant genome dynamics. Here,
we analyze the evolutionary dynamics of repeats in tetraploid and hexaploid Spartina …

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 …

In this paper, we examine how the Spartina system has helped our understanding of the
genomic aspects of allopolyploid speciation in the context of biological invasion. More …

Transposable elements (TE) induce structural and epigenetic alterations in their host
genome, with major evolutionary implications. These alterations are examined here in the …

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

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

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 …

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 …

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 …
