Starch accumulation (A) and degradation (B) in synchronized Chlamydomonas cells. (A) Averaged cellular starch content during 6 h illumination as determined by microscopic analysis (A; square, right axis) or by the enzyme-based assay (A; circle, left axis). Average of two independently performed experiments ± SD (n = 2) are given. (B) After 6 h illumination, starch degradation was initiated by the addition of DCMU (B; triangle and diamond) or by darkening (B; circle and square). The averaged cellular starch content was determined by microscopical analysis (B; diamond and square; right axis) or by the enzyme-based assay (B; cirlce and triangle; left axis). Means of two independently performed experiments ± SD are given (n = 2).
