Special series on Antarctic Research

This special issue on Antarctic research in Biological Research comprises of recent studies, related to the discovery of several new enzymes and biotechnological applications. The desiccation resistance of an Antarctic moss Sanionia uncinata and antioxidant responses of Colobantus quitensis, one of the two vascular plants that exist in Antarctica, are presented. There is also research on heat shock protein 70 from a sea urchin, studies on the high levels of UV-B radiation in Antarctica, studies on the accumulation of UV B absorbing compounds in Antarctic bryophytes and a bryological study of site ASPA 125 in King George Island. These scientific contributions allow to expand the knowledge of Antarctic organisms and their potential applications.
