This research discovered eight new viruses infecting marine microorganisms called Halophytophthora that live in coastal waters. This is the first time these types of viruses have been found in marine organisms of this group. The study helps us understand the complex relationships between viruses and marine life. Impacts on everyday life: – Improves our understanding of marine ecosystem health and functioning – Provides insights into evolution of viruses in marine environments – May help explain patterns of marine plant diseases – Could lead to better management of coastal habitats – Advances knowledge of virus diversity in ocean environments
