Flagellar regeneration. Mean flagellar length (micrometers) ± SEM versus time after deflagellation. C. reinhardtii were deflagellated at time 0 and then allowed to regenerate in minimal medium (M), or M containing 3 mg/ml colchicine, 10 μg/ml cycloheximide, or 50 μg/ml actinomycin D. Pooled data from an entire class (all groups in each of four lab sections, n = 17) were used for curves representing control (M) and colchicine conditions; pooled data from the subset of groups using each particular experimental condition were used for curves representing cycloheximide and actinomycin D (n = 5). Mean flagellar length of nondeflagellated controls measured at 0 and 105 min (9.3 μm) is indicated by the arrow.
