Distinct Mechanisms Regulating Gene Expression Coexist within the Fermentative Pathways in Chlamydomonas reinhardtii

Figure 4

Diagram depicting the fermentative pathways of Chlamydomonas split into 3 functional subpaths based on response profile to circadian inputs, light (dark), and oxygen in cells synchronized to a 12 h : 12 h light : dark photoperiod and grown at 23°C. In red: LDH1, ADH1, ADH2, and PDC3 which are under circadian regulation. In green: PFL1 which did not show a circadian pattern of expression, nor did it respond to changes in light (dark) or oxygen. In blue: PFR1 and HYD1 which both show circadian expression patterns and are also responsive to changes in oxygen, but not to changes in light.
