Chromosomes of Iberian Leuciscinae (Cyprinidae) Revisited: Evidence of Genome Restructuring in Homoploid Hybrids Using Dual-Color FISH and CGH

Popis výsledku v původním jazyce

Iberian Leuciscinae have been used in many studies as models to explore topics such as hybridization, allopolyploidy, modes of reproduction, and evolution. This article focuses on the contribution of cytogenomics to foster research in this group of cyprinid fish. Conventional and molecular banding results were reviewed, facilitating comparative analysis between nase and chub taxa inhabiting Portuguese freshwaters. Hybridization is known to occur within both Chondrostoma s.l. and Squalius genera althoughpolyploidy has only been reported in the latter; the reasons behind such differential genome flexibility remain unidentified. FISH tools allowed recognizing additional chromosome markers, confirming NOR polymorphism and distinguishing species and theirhybrids. Recombination and genome instability were detected in homoploid and polyploid hybrid genomes supporting active NOR transposition. However, the multiplication of rDNAs in these species does not seem to be associated with Rex3 retr
