IAS Benjamin Meaker Visiting Professor Harald Schneider will lead a research discussion entitled "Whole genome duplication in plant evolution".

Synopsis: Whole genome duplications have been considered as a major mechanism in the evolution of land plants. Testing this hypothesis requires arguably different approaches to elucidate all crucial aspects of the evolution of polyploidy in land plants. The discussion seminar will highlight several crucial components by focusing on ferns in comparison to seed plants.

Whole genome duplications are frequently involved in the speciation processes of ferns leading to a high frequency of neopolyploid species whereas evidence for evolutionary innovations driven by paleopolyploidy is scarce in ferns. This pattern differ substantially from the pattern discussed in seed plants.

In this discussion meeting, I will introduce several aspects of the biology of ferns that may explain the high frequency of neopolyploidy whereas the role of whole genome duplication as innovation drivers is arguably limited in ferns. Special attention will be given to the question why whole genome duplication may influence the response of plants to increased extinction risks.
