THE OCCURRENCE OF CHLOROPHYLLS <i>C</i>₁ AND <i>C</i>₂ IN THE CHRYSOPHYCEAE¹

Abstract

ABSTRACT We analyzed 34 strains representing 25 species of Chrysophyceae for chlorophylls c 1 and c 2 using thin‐layer chromatography. Most organisms had both chlorophylls c 1 and c 2 in addition to chlorophyll a but 17 strains of 9 species of Synura and Mallomonas possessed only chlorophylls a and c 1 . These are the first chlorophyll c‐bearing algae which lack chlorophyll c 2 . We postulate 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.
