TL;DR: Despite the recent advances in the understanding of polyploid evolution, many exciting aspects remain under-investigated, and some of these include the consequences of genetic and genomic changes in naturalpolyploid populations, the physiological and ecological effects of polyPLoidy, and whether recurrent polyploidsy prompts evolution to repeat itself.

TL;DR: It is suggested that the unusual morphological features of the tetraploids are the result of convergent evolution and not shared ancestry, and neither the nuclear nor the chloroplast phylogeny supports monophyly of Tarasa as currently circumscribed.

TL;DR: It is shown that multiple origins of a polyploid species not only affect patterns of genetic variation in natural populations, but also contribute to differential patterns of gene expression and may therefore play a major role in the long-term evolution of polyploids.

TL;DR: The results suggest that regulation of gene expression is relaxed in a concerted manner upon hybridization, and new patterns of partitioned expression subsequently emerge over the generations following allopolyploidization.

TL;DR: Synthetic F1 hybrids between putative diploid progenitors are additive of their parental genomes, suggesting that polyploidization rather than hybridization induces genomic changes in Tragopogon.
