Origin and genomic evolution of polyploid complexes in Melampodium (Asteraceae)

A combination of methods and techniques is used to analyze in detail the origin and evolution of allotetraploids and allohexaploids of Melampodium. Phylogenetic and phylogeographic approaches are employed to elucidate the evolutionary origin and history of this complex, and are complemented by in-depth analyses of genome evolution following polyploidization, with a focus on repetitive DNA. The comparative investigation of this polyploid complex addresses evolutionary questions concerning the impact of origin and evolutionary history of polyploids on the type and frequency of genomic changes contributing to speciation.
