FIG 3.

R2lc activates AhR independent of AraT. (A) AraT is not the main driver of AhR activation by R2lc. (B) Deletion of the araT gene in 6475 does not significantly change the AhR activation level in L. reuteri 6475. Data shown represent averages of results from three biological replicates, and error bars represent standard deviations. Statistical significance between strains and the negative control was determined by the one-sample t test. Statistical significance between strains was determined with Student’s t test. ns, not significant; WT, wild type.
