Differences in the synthesis of chlorophyll a and chlorophyll b in the course of the chlorella vulgaris cell cycle


, : Differences in the synthesis of chlorophyll a and chlorophyll b in the course of the chlorella vulgaris cell cycle. Fiziologiya Rastenii (Moscow) 26(2): 378-382

Changes in the rates of chlorophyll a and b syntheses were investigated in synchronously dividing cells of C. vulgaris Beijer, and difference absorption spectra were measured in intact cells differing in age by 1 h. Chlorophyll b was synthesized with a constant rate during the 5-8th h of the light period and was not synthesized at other times of the cell cycle. The rate of chlorophyll a synthesis reached the maximal value by the 5-6th h of the light period. The chlorophyll a/chlorophyll b ratio varied from 3, at the onset and at the end of the light period, to 6.5 by the 5th h of the light period. During the cell cycle of Chlorella the synthesis of the light-harvesting chlorophyll-protein complex apparently occurs only after formation of the pigments of photosytem 1 and 2, and the individual spectra forms of chlorophyll a are incorporated by turns into the body of the photosynthetic membrane.
