Membrane-associated σ factors disrupt rRNA operon clustering in Escherichia coli
Fig 3
Disruption of rrn clustering by heat stress and by FecI.
(A) Effect of heat stress on clustering of indicated rrn pairs. Other descriptions as in Fig 1. (B) Schematic summary of data in A. Each of the 7 rrn operons was visited at least once. (C) Response to rpoH induction of tested rrn pairs. +/− symbols are self-explanatory. (D) Effect of induced ectopic expression of five σ factors on rrnA-D distance, all placed under control of pTc with the same RBS. Data used for plotting Fig 3 graphs can be found in the Supplemental “S1 Data” file under appropriate figure headings. Created in BioRender. Ho, K. (2025) https://BioRender.com/g63t231.
