a The ancestral Pxr blocks M. xanthus development in a DK1622/GJV1-derived genomic background. Spore production of the OC Δpxr strain carrying the pxr ancestor and the control strains are shown. Arrows indicate that no spores were observed at the lower limit of detection. Error bars represent standard deviations. b Northern blot showing the expression of Pxr-L and Pxr-S produced by the OC Δ pxr strain carrying the pxr ancestor and the control strains. The asterisk marks binding of the probe to non-Pxr RNAs
