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.
一项关于45种十字花科植物中rDNA位点的数量和染色体位置的调查。对于34种植物，首次通过双色荧光原位杂交对5S和45S rDNA位点进行了定位。这些数据显示了十字花科核型内rDNA的变异性，为（比较）遗传图谱提供了锚定位点，并且可能对十字花科植物中rDNA内转录序列类型的协同进化研究具有重要意义。
