    <t>(A–D)</t> <t>ChIP-seq</t> profiles showing Rob binding at the promoter regions of meoA (A), tolC (B), mlaF (C), and atpI (D). Blue tracks represent normalized ChIP-seq signal in the control strain (top) and Rob-tagged strain (bottom). Gene orientations are indicated by arrows; scale bar, 500 bp. (E) Schematic model of Rob-dependent transcriptional regulation. Rob binding upstream of target operons activates genes involved in outer membrane permeability ( ompF/ompD ), multidrug efflux ( tolC–acrAB2 ), and phospholipid transport ( mla operon). (F) Relative expression of selected Rob regulon genes measured by qPCR, shown as fold change normalized to wild type (WT). Data represent mean ± SD. The red dashed line indicates WT expression level. (G) Corresponding fold changes in gene expression derived from RNA-seq analysis, normalized to WT, confirming global upregulation of Rob target genes. (H) Efflux activity measured over time using a fluorescence-based assay. Rob mutant exhibits significantly higher efflux compared to the WT. Data are shown as mean ± SD; **** indicates P < 0.0001.
