| 摘 要： | 于１９９２年６月－１９９３年４月，对钝顶螺旋藻质粒进行透射电镜观察及分子杂交研究。结果表明，利用层分子膜展开技术，能够观察到超螺旋以及闭合环形的质粒图象；Ｓ６质粒大小的平均值约为２．０ｋｂ，与电泳检测的结果稍有出科。斑点杂交结果表明，不同形态藻株Ｓ６、Ｆ３、Ｆ３弯与Ｆ３直质粒之间具有一定同源性，与染色体ＤＮＡ之间均显示同源性。对钝顶螺旋藻质粒的进一步研究将推动其基因工程育种的开展。

| Abstract: | Transmission electron microscopic observation and hybridization study of the Plasmid from Spirulina platensis were carried out from June, 1992 to April, 1993.Supercoiled and closed circular patterns were observed under a transmission electron Wicroscope. The size of the plasmid from S6 strain was about 2.0kb, which Was slightly different from the result of electrophoresis. Results of dot blotting show that plasmids from strains of S6, F3, F3 spiral and F3 stfaight differing in form are komologous to each other and are also homologous to chromosomal DNAs. |
