Northern gel analysis of the early expression of hetR after nitrogen starvation in wild type and the hetR point mutant 216. The lane labels refer to hours postinduction. The 0.5-h 216 lane is blank, likely to be a result of sample degradation, and the 1.9-kb band in the 216 3.0- and 4.0-h lanes is distorted because of an air bubble during transfer of the RNA.
