Abstract

Forty unicyanobacterial cultures of the genus Scytonema were investigated, which had been isolated from several terrestrial habitats around the world (Europe, America, Southeast Asia, Australia, and Africa). The following were detected: four phycobiliproteins (allophycocyanin [aPC], phycocyanin [PC], phycoerythrocyanin [PEC], and phycoerythrin [PE]); six carotenoids (β-carotene, canthaxanthin, echinenone, isozeaxanthin, myxoxanthophyll, and zeaxanthin); 14 different mycosporines, including shinorine, stanierine, and asterina-330; and the presence of scytonemin. Three incidence patterns were determined for phycobiliproteins, carotenoids, mycosporine-like amino acid (MAA) compounds, and scytonemin from among the species belonging to the Scytonema genus, which were not related according to their biogeographic origins. The first was made up of species with aPC and PC, and β-carotene, canthaxanthin, echinenone, and zeaxanthin; they lacked MAAs but possessed scytonemin. The second was formed by species containing aPC, PC, and PE; and β-carotene, canthaxanthin, echinenone, isozeaxanthin, and myxoxanthophyll. They also presented MAAs and scytonemin. The third comprised species with a similar aPC, PC, and PEC pattern; β-carotene, canthaxanthin, and echinenone; shinorine-type MAA; and lacking scytonemin, which grew in dimly lit places. aPC, PC, PE, and PEC; isozeaxanthin, myxoxanthophyll, and zeaxanthin; shinorine, asterina-330, and mycosporine no 13; and scytonemin showed statistically significant variations between the three groups of Scytonema unicyanobacterial cultures. Our results suggest that the performance of the phycobiliproteins, carotenoids, MAA compounds, and scytonemin used as chemotaxonomic markers should be employed as a tool to taxonomically or phylogenetically study the Scytonema genus, thus improving the current morphology-based classification system.
