Abstract

Nucleolar organizer regions (NOR's) were demonstrated in metaphase chromosomes of the domestic rabbit. Oryctolagus cuniculus (L.) (New Zealand white strain) using silver staining. Sequential quinacrine banding and a modification of the Ag-AS silver precipitation technique with duplicate photography allowed identification of silver staining NOR's on the short arms of chromosomes 13, 16, and 20, as well as the telomeric region of the long arms of number 21 in some cells. Chromosomes 13, 16 and 20 all have subterminal to terminal centromeres, often showed satellites and secondary constrictions, and were sometimes involved in associations.

摘要

采用银染法在家兔（穴兔新西兰白兔品系）有丝分裂中期染色体上显示核仁组织区（NORs）。连续的喹吖因显带以及对Ag-AS银沉淀技术的改进并进行双重摄影，能够在13号、16号和20号染色体短臂上以及部分细胞中21号染色体长臂的端粒区域鉴定出银染的NORs。13号、16号和20号染色体均具有亚端粒到端粒的着丝粒，常显示出随体和次缢痕，并且有时会参与联会。
