JGI-Enabled Research Finds Flagella in the Terrestrial Roots of Marine Bacteria

October 19, 2023

Scientists have discovered flagella in an unexpected place: hot spring-dwelling bacteria from the phylum Chloroflexota. Research shows that flagella were lost in other forms of Chloroflexota that adapted to marine environments hundreds of millions of years ago.

Studying the Tiniest Archaea, JGI Users Find a Genomic Switch of Friend or Foe

October 12, 2023

Within the archaeal domain, there is a group of tiny hitchhikers. These organisms are abundant and yet exceptionally small, with mini genomes to match. To fill in their nutrient gaps, they must latch onto a larger host — often, a fellow archaeal microbe. Recently, researchers used population genomics to find that while archaeal hitchhikers may often act as parasites, in other cases, they likely help their hosts.

JGI Researchers Provide a Perspective on Giant Virus Diversity

November 21, 2022

In the last thirty years, in environments all over the world, scientists have discovered giants among viruses. Culturing studies have been key to understanding these viruses’ host range, morphological structures, and infection strategies. More recently, researchers have employed cultivation-independent approaches to discover thousands of new giant viruses, rapidly expanding the diversity of the Nucleocytoviricota phylum. A new review provides a perspective on giant virus diversity, and how sequencing and bioinformatics have sped up the study of giant viruses.
