Temperature modulates dominance of a superinfecting Arctic virus in its unicellular algal host

Complex virus-virus interactions can arise when multiple viruses coinfect the same host, impacting infection outcomes with broader ecological and evolutionary significance for viruses and host. Molecular interference of two dsDNA viruses which infect an important Arctic algal host, Micromonas polaris, was studied in co-infection experiments with the aim of elucidating some of these complex viral interactions.
