Quantification of chlorophyll and carotenoid content of dark-grown lts1 and pds1 mutants.

Chlorophyll (Chl) and carotenoid quantities (represented as fmol/cell) were extracted from a total of 1×108 cells for each sample with 200 µl of acetone. Colored carotenoids detected in C. reinhardtii include α-carotene, β-carotene, lutein, violaxanthin, antheraxanthin, neoxanthin, loroxanthin, zeaxanthin. Total xanthophylls include lutein, loroxanthin, violaxanthin, antheraxanthin, neoxanthin, and zeaxanthin. Averages and standard deviations are from three independent cultures.
