The Trojan Horse gene of the marine virus

Researchers at Technion Faculty of Biology discovered that marine viruses deploy a sophisticated Trojan horse maneuver to dismantle ocean bacteria's energy systems, using the breakdown products for self-replication. This process reduces global photosynthetic energy production by about 5% and could impact global carbon and oxygen cycles.
