Researchers discovered that two species of marine bacteria work together to produce vitamin B12, essential for metabolism and survival of many marine organisms. The bacteria release building blocks into the water, which are then combined to form the vitamin through a complex process involving viral infection.
Researchers have proposed a new evolutionary model for the origin of the Bamfordvirae kingdom of viruses, suggesting a billion-year evolutionary arms race between two groups and their hosts. The study reveals strong evidence against a sister relationship between adenoviruses and NCLDVs, instead supporting a common ancestor with Mavericks.
Researchers found over 30,000 unknown viruses integrated into the DNA of single-celled eukaryotic organisms, including algae and human parasites. These 'virophages' may protect their hosts from giant virus infections by reprogramming them to build virophages.
Researchers uncover 25 novel virophage sequences, doubling the known number of these tiny viral parasites. This discovery sheds light on their ecological role and importance in shaping lake ecosystems.
Researchers found that giant viruses share genes with tiny virophages and transposable elements, suggesting they evolved from each other on multiple occasions. The study's complex network of evolutionary relationships challenges previous understanding of viral evolution.
