From minor loci to major players? Satellite DNA diversification in Crepis sensu stricto.

ABSTRACT: Crepis sensu lato (s.l.) comprises species with remarkable variation in genome size, chromosome number, and karyotype structure, making this genus a valuable model for studying genome and chromosome evolution. Studies in various plant systems have suggested that diversification and speciation may be accompanied by dynamic changes in the repetitive DNA fraction, including satellite DNAs (satDNAs). A complex approach consisting of molecular (cloning, dot-blot and Southern hybridisation), cytogenetic (fluorescent in situ hybridisation) and phylogenetic methods allowed assessing the chromosomal and genomic organisation of three satDNAs in 32 species from Crepis s.l.. In the present study, we posed a question of whether these satDNAs are specific to C. capillaris, supporting the "birth-and-deat
