By the way, a table with all the prokaryotic multicellular species we could find is in the supplementary material. Did we miss a species you know? I'd love to keep expanding it with more multicellular prokaryotes. Always happy discuss this, and everything else about prokaryotic multicellularity.
Voir le postAnd this is the point. The diversity of living and extinct prokaryotic species, and of their multicellular solutions is bewildering. Multicellularity spans the whole tree of life. We need theories that account for the diversity of ways in which multicellularity -and with it development- evolves.
Voir le postAnd finally: evolution. Bacteria LOVE to turn multicellular. A predator threat? Evolve multicellularity. Starvation? Evolve multicellularity. Lots of salt? multicellularity. Little salt? multicellularity... Of course, different species respond differently to different ecological opportunities.
Voir le postWe then discuss the molecular implementation in prokaryotes of those 'hallmarks' that are typical of multicellularity. These are adhesion, cell communication, using gene regulation networks for cell differentiation, division of labour, and programmed cell death.
Voir le postThe point of the review is to think about bacteria and archaea as multicellular organisms. We discuss: - how prokaryotes form groups, and how their multicellular structures develop, be they biofilms, filaments, suspended aggregates... - and their "soft" similarity to some eukaryotic structures.
