Highly diverse and unknown viruses may enhance Antarctic endoliths’ adaptability
BackgroundRock-dwelling microorganisms are key players in ecosystem functioning of Antarctic ice free-areas. Yet, little is known about their diversity and ecology, and further still, viruses in these communities have been largely unexplored despite important roles related to host metabolism and nut...
