Acipenseriformes is an order of ray-finned fishes, comprising 27 extant species of sturgeons and paddlefishes inhabiting waters of the Northern Hemisphere. The order has a basal position within Actinopteri (ray-finned fish minus polypterids) and is characterized by many specific morphological and genomic features, including high diploid chromosome numbers, various levels of ploidy between species, unclear sex determination, and propensity to interspecific hybridization. Recent advances in molecular genetics, genomics, and comparative cytogenetics produced novel data on different aspects of acipenseriform biology, including improved phylogenetic reconstructions and better understanding of genome structure. Here, we discuss the cytogenetic and genomic traits of acipenseriforms and their connection with polyploidization and tolerance to interspecific hybridization.
