These PCR reactions resulted in 3 kb amplicons which were cloned into the integration vector pNZ5319 [63] after prior digestion of the vector with SwaI and Ecl136II. Plasmids were transformed into competent cells of E. coli JM109 by electroporation as recommended by the manufacturer (Invitrogen). Plasmid DNA was isolated from E. coli using Jetstar columns (Genomed GmbH, Bad Oeynhausen, Germany) using the manufacturer’s recommended protocol. DNA sequencing (BaseClear, Leiden, The Netherlands) was performed to confirm the integrity of the cloned genes. The resulting plasmids containing the complete gene replacement cassettes were used

a Bold and underlined nucleotides signify overlapping ends with the Ecl-loxR and Pml-loxF primers. Statistical analysis Linear mixed effect models using restricted maximum likelihood (REML) were used to statistically compare the mean cytokine values of IL-10, IL-12, and IL-10/IL-12 produced in response to L. plantarum wild-type and mutant cells. The effect of the donor on the response variable was modeled as a random effect. The fixed effects in the model were the strains (WCFS1 [wild type], Δpts19ADCBR, Δlp_1953, ΔplnG, ΔplnEFI, and ΔlamA ΔlamR) and the growth phase at the time of harvest (exponential phase and stationary phase). Logarithmic transformations of [IL-10], [IL-12] and [IL-10]/[IL-12] yielded residuals that showed approximately normal distributions (data not shown) and, hence, were used as the response variables in the fitting procedure. Statistical analysis was performed using R http://​www.​r-project.​org, with the package “”nlme”" [65] for mixed effect modeling.
