The possible usefulness of polyamines as chemotaxonomic markers has been investigated in eukaryotic algae. Polyamines were analyzed in 12 species of primitive unicellular eukaryotic algae including some anomalous species. Norspermidine and norspermine in addition to putrescine and spermidine are widely distributed in most unicellular species of the algae. However, neither norspermidine nor norspermine was found in the taxonomically conflicting algae, Cyanophora and Glaucocystis, which contain cyanellae, or in a primitive red alga, Porphyridium. A thermoacidophilic eukaryotic alga, Cyanidium, is rich in both norspermidine and norspermine. Appreciable amounts of spermine and sym-homospermidine were detected only in the species belonging to the Rhodophyta (red algae).

1 This study was supported in part by Grants-in-Aid for Scientific Research from the Ministry of Education, Science and Culture of Japan.
