In bacterio replication of pZErO-2 by D. discoideum Twm1. E. coli BL21 strains each possessed two vectors; pET-23a:tetA either as an empty vector (−) or encoding Twm1 (+), and pZErO-2 with (+) or without (−) the NCRrnl or rnl region of the D. discoideum mitochondrial genome. Twm1 expression was induced by the addition of 1 mM IPTG. Relative pZErO-2 vector copy number (using primers for kanR) was quantified using qPCR against a single copy number bacterial gene, talB. Error bars represent the standard error. p values were calculated using Student’s t-test (*< 0.05; **< 0.001)
