Unraveling the Unusual Subgenomic Organization in the Neopolyploid Free-Living Flatworm Macrostomum lignano.

ABSTRACT: Whole genome duplication (WGD) is an evolutionary event resulting in a redundancy of genetic material. Different mechanisms of WGD, allo- or autopolyploidization, lead to distinct evolutionary trajectories of newly formed polyploids. Genome studies on such species are important for understanding the early stages of genome evolution. However, assembling neopolyploid is a challenging task due to the presence of 2 homologous (or homeologous) chromosome sets and therefore the existence of the extended paralogous regions in its genome. Post-WGD evolution of polyploids includes cytogenetic diploidization leading to the formation of species, whose polyploid origin might be hidden by disomic inheritance. Earlier we uncovered the hidden polyploid origin of the free-living flatworms of the genus Mac
