Unconventional cell division in the Caribbean Sea

(University of Vienna) Bacteria are immortal as long as they keep dividing. For decades it has been assumed that a continuous, proteinaceous ring is necessary to drive the division of most microorganisms. An international team led by Silvia Bulgheresi, University of Vienna, revealed that the symbiont of the marine roundworm breaks the ring dogma and divides without. These findings have been published in the current issue of Nature Microbiology.
