Mycosporine-like amino acids from coral dinoflagellates.
Coral reefs are one of the most important marine ecosystems, providing habitat for approximately a quarter of all marine organisms. Within the foundation of this ecosystem, reef-building corals form mutualistic symbioses with unicellular photosynthetic dinoflagellates of the genus Symbiodinium. Exposure to UV radiation (UVR) (280 to 400 nm) especially when combined with thermal stress has been ...
متن کاملPackaging of mycosporine-like amino acids in dinoflagellates
Synthesis of mycosporine-like amino acids (MAAs) can significantly protect phytoplankton cells against damaging ultraviolet (UV) radiation, depending on the concentration, type and cellular distribution of these UV sunscreens. We addressed the hypothesis that MAAs are concentrated around UV-sensitive organelles for improved efficiency, thereby increasing their ‘package effect’. This was investi...
متن کاملThe synthesis of mycosporine-like amino acids (MAAs) by cultured, symbiotic dinoflagellates.
We tested the hypothesis that there is a relation between phylotypes (phylogenetic types, as determined by restriction fragment length polymorphism (RFLP) and partial sequence analysis of the small subunit ribosomal RNA gene (SSUrDNA)) and the synthesis of mycosporine-like amino acids (MAAs) by symbiotic dinoflagellates under the influence of ultraviolet radiation (UV-B/A) and photosyntheticall...
متن کاملSurvey of ultraviolet radiation-absorbing mycosporine-like amino acids in organs of coral reef holothuroids*
Twelve deposit-feeding species of tropical holothuroid echinoderms (families Holothuriidae and Stichopodidae) were surveyed for the presence of UV-absorbing mycosporine-like amino acids (MAAs) during Austral summer at Hicks Reef, Great Barrier Reef (GBR). An additional species belonging to the Synaptidae was collected in Austral winter from Shrimp Reef, GBR. Tissues of all species contained MAA...
متن کاملMycosporine-Like Amino Acids: Potential Health and Beauty Ingredients
Human skin is constantly exposed to damaging ultraviolet radiation (UVR), which induces a number of acute and chronic disorders. To reduce the risk of UV-induced skin injury, people apply an additional external protection in the form of cosmetic products containing sunscreens. Nowadays, because of the use of some chemical filters raises a lot of controversies, research focuses on exploring nove...
