用银染法分析了45只野生小鼠染色体上核仁组成区(Ag-NORs)的分布。所代表的四个亚种分别是肌肉分枝杆菌、磨牙分枝杆菌、卡氏分枝杆菌和巴氏分枝杆菌。在11条染色体(4、8、9、10、11、12、15、16、17、18和19)着丝粒附近观察到Ag-NORs，表明小染色体上的Ag-NORs占优势。前五个基因座以前从未被观察到。提示小鼠Ag-NORs的特异性可能与rDNA的染色体内和染色体间均质化有关。
A silver staining method was used to analyze the distribution of nucleolar organizer regions (Ag-NORs) on chromosomes of 45 wild mice (Mus musculus). The four subspecies represented were M. m. musculus, M. m. molossinus, M. m. castaneus, and M. m. bactrianus. Ag-NORs were observed near the centromeric regions of 11 chromosomes (4, 8, 9, 10, 11, 12, 15, 16, 17, 18, and 19), indicating a preponderance of Ag-NORs on smaller chromosomes. The first five loci have not been observed previously. It is suggested that a correlation may exist between the specific features of mouse Ag-NORs and the events involved in intra- and interchromosomal homogenization of rDNA.
