Abstract
In the current paper we described the application of primed in situ (PRINS) labeling approach for the chromosomal mapping of repetitive DNA sequences in Danube salmon (Hucho hucho) (2n = 82, NF = 112). PRINS was successfully performed with primers enabling amplification of 5S rRNA genes (minor rDNAs), NOR building DNA sequences (major rDNAs), and telomeric sequences. Two loci of 5S rRNA were observed on distinct chromosome pairs; the minor arrays were located interstitially on the long (q) arms of two large metacentrics (chromosomes No. 3) and the large clusters of 5S rDNAs were assigned to the short (p) arms of two subtelocentric chromosomes No. 18. Major rDNA clusters were observed on the p-arms of two submeta-subtelocentric chromosomes No. 10. These chromosomal areas were built with GC-rich chromatin what was proved in the course of chromomycin A3 (CMA3) staining performed sequentially. Major and minor rDNA families were not co-localized in the Danube salmon chromosomes.The distinct hybridization signals at the ends of all the chromosomes were provided in the course of PRINS with (CCCTAA) n primer. The chromosomal localization of rRNA genes and telomeric DNA sequences was discussed in the context of Salmonidae karyotype evolution.
