The occurrence of chlorophylls c sub(1) and c sub(2) in the Chrysophyceae

The authors analyzed 34 strains representing 25 species of Chrysophyceae for chlorophylls c sub(1) and c sub(2) using thin-layer chromatography. Most organisms had both chlorophylls c sub(1) and c sub(2) in addition to chlorophyll a but 17 strains of 9 species of Synura) and Mallomonas possessed only chlorophylls a and c sub(1). These are the first chlorophyll c-bearing algae which lack chlorophyll c sub(2). It was postulated that at least some of the silica-scaled algae including Mallomonas) and Synura may be distinct from other Chrysophyceae based upon pigmentation and other characters described in the literature.
