Marine bacteria are the most abundant organisms on Earth; indeed, the worlds oceans contain as many as 1.18 10 29 prokaryotes and play a key role in climate regulation [32].Despite the vital role of microorganisms (photosynthetic and heterotrophic bacteria) in marine ecosystems, crucial in the major biogeochemical balances of the planet, their functioning is still not well 3. 2 In fact, most of the serotonin in your body is found in your gut, not your brain. A short summary of this paper. It is an evolutionarily conserved signaling cascade regulating numerous biological processes, including cell growth and fate decision, organ size control, and regeneration. This versatility originates from polyubiquitin chains, which can be linked in eight distinct ways. 2.1.
