Comparison among three models. A. Relationships between cell growth rate and either plasmid copy number. B. Relationships between cell growth rate and the total amount of exogenous DNA.. The black and red open squares represent the data for the host strains MG1655 and MDS42, respectively. The bars represent the standard errors of triplicates. The solid, broken and chained lines denote the regression lines for the three models represented by Eqs. 1 (model 1), 2 (model 2) and 3 (model 3), respectively.
