From: A positive feedback loop mediated by Sigma X enhances expression of the streptococcal regulator ComR
Transcriptome map showing expression of comR and its upstream region in S. mutans ΔcomS grown in the presence (black) or absence (light gray) of XIP in chemically defined medium. The images are superimposed to illustrate the differences in expression between the two conditions, starting next to the predicted intragenic SigX box. The axis on the left represent the log2 average of read counts of normalized individual duplicated samples for each condition, as detailed in material and methods.
