▪ Abstract Here we review the biology of early generation neopolyploids and discuss the
profound changes that accompany their formation. Newly formed auto-and allopolyploids …

Polyploidy has long been recognized as a prominent force shaping the evolution of
eukaryotes, especially flowering plants. New phenotypes often arise with polyploid formation …

Allotetraploid oilseed rape (Brassica napus L.) is an agriculturally important crop. Cultivation
and breeding of B. napus by humans has resulted in numerous genetically diverse …

Polyploidy has contributed to the evolution of eukaryotes, particularly flowering plants. The
genomic consequences of polyploidy have been extensively studied, but the mechanisms …

Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Many previous studies have provided evidence for genome changes in polyploids, but there
are little data on the overall population dynamics of genome change and whether it causes …

Mitogen-activated protein kinase (MAPK) signaling plays a central role in transducing
extracellular stimuli into intracellular responses, but its role in mediating plant responses to …

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

A fundamental precept of evolutionary biology is that natural selection acts on phenotypes
determined by DNA sequence variation within natural populations. Recent advances in our …

The joining of different genomes in allotetraploids played a major role in plant evolution, but
the molecular implications of this event are poorly understood. In synthetic allotetraploids of …
