蝙蝠科三种蝙蝠的G-带和C-带

对肺、心等进行组织培养,用空气干燥法制作染色体标本,对贵州3种蝙蝠即中华鼠耳蝠(Myotis chinensis)、西南鼠耳蝠(M.altarium)和亚洲长翼蝠(Miniopterus fuliginosus)进行了G-带、C-带带型分析。结果表明,2种鼠耳蝠的G-带基本相同,亚洲长翼蝠的G-带与两种鼠耳蝠有一定同源性;C-带核型中,中华鼠耳蝠和亚洲长翼蝠只有着丝粒带,而西南鼠耳蝠有的染色体有插入C-带和端位C-带。根据带型异同分析讨论了鼠耳蝠和长翼蝠间的进化关系。

G-bands and C-bands in 3 Species of Vespertilionidae

Chromosome preparations were made from culture cells from lung and heart tissues etc.The specimens were made by the standard air drying method.The G-and C-bands of 3 species of bats (Myotis chinensis,M.altarium and Miniopterus fuliginosus) from Guizhou were analyzed.The G-band technique reported by Seabright (1971) and C-band technique reported by Sumner (1972) were applied.The G-bands of Myotis chinensis and M.altarium were similar and partly homologous with those of Miniopterus fuliginosus.As to the C-bands,all the 3 species of bats possessed centromeric heterochromatin,but interstitial heterochromatin and terminal heterochromatin distributed only in some chromosomes of Myotis altarium.At last,the evolutionary relationship between the 2 different genera was discussed according to their similarities and differences in banded karyotypes.
