Phenotyping of Chlamydomonas under N depletion and recovery. a A time course (0, 5, 25, 72, 77, 96 h) was sampled and cell number was measured as well as variation in the fresh weight (b). Chlorophyll a plus b concentration (c) and maximum quantum efficiency of photosystem II (Fv/Fm) (d) were measured for each time point. Total lipids amount (e) and starch measurement (f) in C. reinhardtii under nitrogen stress (Up to 72 h) and nitrogen recovery (72–96 h) (n = 4)
