Content overview: “First Cultivation of Heimdallarchaeia, Our Closest Archaeal Relatives, Sheds Light on Euka”. A team led by Hiroyuki Imachi and Masaru K. Nobu of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) and Satoshi Nakagawa of Kyoto University has successfully isolated and cultivated two strains of Heimdallarchaeia. These archaea are considered among the closest known archaeal rela These archaea are considered among the closest known archaeal relatives of eukaryotes—the domain that includes all animals, plants, and fungi.
The breakthrough, achieved after years of effort, opens new avenues for studying the evolutionary transition from simple microbes to complex cells. Heimdallarchaeia belong to the Asgard archaea, a group discovered in deep-sea sediments and hydrothermal vents. Their genomes contain many genes previously thought to be unique to eukaryotes, including those involved in membrane remodeling and intracellular trafficking.
