Expression of bprJ2 in BPLOW. RNA was extracted at t = 10 h from a non-modulated B. pertussis culture (lane 1), from a MgSO4 modulated culture (lame 2), from a nicotinic acid modulated culture (lane 3) and from a BPLOW culture (lane 4). BprJ1 and BprJ2 transcript positions are indicated. L, RNA size ladder. RNA sizes are indicated in nucleotides in the left margins of each panel. The detection of 5S rRNA was used as loading control.
