Abstract

A survey is given about the number and chromosomal position of rDNA loci in 45 Brassicaceae species. For 34 species, 5S and 45S rDNA loci have been localized by two-colour fluorescence in situ hybridization for the first time. These data show the variability of rDNA within karyotypes of the Brassicaceae, provide anchor points for (comparative) genetic maps, and might be important for studies on concerted evolution of internal transcribed sequence types of rDNA in cruciferous plants.
