Abstract
High copy number plasmids have been identified in six out of 25 wild-type strains of the cellular slime mould Dictyostelium discoideum, a model organism in developmental biology (Loomis, 1982). The characterization of three plasmids, from the NC4 (Ddp1), WS380B (Ddp2) and OHIO (Ddp3) wild isolates, is presented here. We show that they are nuclear associated and non-homologous to the mitochondrial DNA and extrachromosomal ribosomal DNA.
摘要
在细胞黏菌盘基网柄菌（发育生物学中的一种模式生物，Loomis，1982）的25个野生型菌株中，有6个已鉴定出高拷贝数质粒。本文介绍了来自NC4（Ddp1）、WS380B（Ddp2）和OHIO（Ddp3）野生分离株的三种质粒的特征。我们表明它们与细胞核相关，并且与线粒体DNA和染色体外核糖体DNA不同源。
