Widespread occurrence of mycosporine-like amino acid compounds in scleractinians from French Polynesia

A survey of 23 species of scleractinians, belonging to seven families and 8 genera, collected from two different areas in French Polynesia, showed that all specimens possessed between four and seven UV-absorbing compounds, identified as mycosporine-like amino acids (MAAs). In all, 11 different MAAs molecules were found, of which two were previously unknown. Palythine and mycosporine-glycine were the most abundant MAAs in the corals. With few exceptions, most specimens of each species possessed the same pattern of MAAs. Similarly, species from the same genus also had very similar qualitative composition of MAAs, although quantities of individuals MAAs varied from specimen to specimen. This suggests that MAAs are ancient and evolutionarily well conserved.
