In this chapter, we focus on aspects and effects of polyploidization in haploid-dominant plants, like bryophytes, which have a dominant haploid gametophyte and a reduced diploid sporophytic generation. What role does polyploidization play in the evolution of these organisms? Can we find evidence of ancient and recent polyploidization events in the genomes of extant bryophytes? What is the importance of auto- versus allopolyploidy? What is the extent of the paranome, i.e. the genomic fraction of paralogs, within a bryophyte genome? What is the prevalent model for functionalization of paralogs and which kind of functional classes of genes have been retained preferentially? We come to the conclusion that the established moss model P. patens and its siblings appears as a model ideally suited to study genome evolution through polyploidization and hybridization in haploid-dominant organisms. Moreover, due to the extensive range of morphological differences of the sporophyte, ranging from the elaborate F. hygrometrica to the vastly reduced P. patens morphology, Funariaceae are an excellent model to study gene-phene evolution. The fact that there is a low breeding barrier among the family also enables crossing and associated genetic studies.
