Characteristics of the nblB mutant. (A) Pigmentation phenotype of hliNG and the nblB mutant in LL, in HL, and during sulfur starvation (−S). Each grouping has four colonies derived from four individual cell aliquots. (B) GUS activity in strain hliNG and the nblB-1 mutant following exposure to HL. (C) Hybridization of labeled probes specific for hliA and nblA to RNA isolated from strain hliNG (lanes 1 to 5) or the nblB-1 strain (lanes 6 to 10) after growth at 10 μmol of photons m−2 s−1 (lane 1 and 6) or following exposure to HL for 30 min (lanes 2 and 7), 1 h (lanes 3 and 8), 2 h (lanes 4 and 9), and 4 h (lanes 5 and 10). rRNA was used as a loading control.
