Expression of selected L. plantarum WCFS1 genes upon tannic acid challenge.

aDesignated gene number for the annotated L. plantarum WCFS1 genome.bMean of fold change (FC) of genes selected in L. plantarum cultures grown in MRS supplemented with tannic acid (test) relative to growth in MRS without supplement (control). Data are for three independent cultures. n.d., not determined.cGenes were considered differentially expressed (highlighted in boldface type) when nominal p-values were dpbp2A is doubly grouped because is a putative PBP-encoding gene linked to GI-survival (see text and [13]).eThe relative expression level of the target gene is significantly different from the level observed in MRS lacking tannic acid at a level pfSignificantly different at a level pgSignificantly different at at a level p
