Characterization of replication origins in S. oneidensis MR-1. (A) Replicon copy numbers of different replication origins in S. oneidensis MR-1 determined by RT-qPCR. (B) GFP expression of various replication origins in S. oneidensis MR-1. S. oneidensis MR-1 harbored a single plasmid carrying pBBR1, p15A, pSC101, or ColE replication origin. In each case, the gfp gene was expressed from the same promoter, pTrc (no repressor lacO). The error bars (mean ± SD) were derived from triplicate experiments for each strain.
