Effects of UV Radiation on the Chlorophyte Host-Virus Interactions and MpoV-45T Virus Infectivity.

Polar seas are under threat of enhanced UV-radiation as well as increasing shipping activities. Considering the ecological importance of marine viruses, it is timely to study the impact of UV-AB on Arctic phytoplankton host-virus interactions and also test the efficacy of ballast water (BW) UV-C treatment on virus infectivity. This study examined the effects of: (i) ecologically relevant doses of UV-AB radiation on RCC2258 and its virus MpoV-45T, and (ii) UV-C radiation (doses 25-800 mJ cm) on MpoV-45T and other temperate algal viruses.
