Abstract

pRm1132f isolated from Sinorhizobium meliloti is a group III rolling-circle-replicating (RCR) plasmid. At least seven of eight open reading frames in the nucleotide sequence represented coding regions. The minimal replicon contained a rep gene and single- and double-stranded origins of replication. Detection of single-stranded plasmid DNA confirmed that pRm1132f replicated via an RCR mechanism.

摘要

从苜蓿中华根瘤菌中分离出的pRm1132f是一种III型滚环复制(RCR)质粒。核苷酸序列中的八个开放阅读框中至少有七个代表编码区。最小复制子包含一个rep基因以及单链和双链复制起点。单链质粒DNA的检测证实pRm1132f通过RCR机制进行复制。
