  Genome-wide duplication events are thought to have contributed to diversification of plants.We study incipient and recent polyploidization to understand the molecular mechanisms involved.Using the Arabidopsis system we analyze the genetic components that lead to successful hybridization and establishment of polyploids.I will describe loci that affect dosage-sensitive responses important in the success of interploidy and interspecific crosses.These loci are consistent with the involvement of both chromatin regulation in the hybrid endosperm and maternal contribution to seed development.
