CHLOROPLAST PIGMENTS OF CHLOROMONADOPHYCEAE
1Scripps Institution of Oceanography, La Jolla, California.
Abstract:
The chloroplast pigments of 2 species of Chloro-monadophyceae have been examined. Both Gonyo-stomum semen and Vacuolaria virescens possessed only one chlorophyll, chlorophyll a. Gonyostomum contained 4 carotenoids, but not fucoxanthin and peridinin. Vacuolaria also possessed 4 carotenoids which have been identified as β-carotene and the 3 xanthophylls commonly found in the Xanthophyceae (as represented by Tribonema aequale). These are antheraxanthin, lutein monoepoxide, and an hydroxy lutein monoepoxide-like xanthophyll. The taxonomic significance of these findings, the first for the Chloromonadophyceae, is discussed.
