FIG. 4.

Induction ratios of LHCBM9 in C. reinhardtii CC124 following anaerobiosis by N₂ bubbling in comparison to sulfur depletion under aerobic or anaerobic conditions. N₂ bubbling, transcripts measured at zero O₂ production and under anaerobic H₂ production conditions; S deplete aerobic, S-depleted cultures bubbled with air to maintain aerobic conditions; S deplete anaerobic, anaerobiosis (microoxic conditions) induced by S depletion. Transcript levels were determined by qRT-PCR and compared to T0 from two to three independent biological replicates (shown are averages ± the standard error; hours show time after S depletion).
