Abb. 1: Chlamydiae, known as bacterial pathogens of humans, originally evolved in single-celled microorganisms long before gaining the ability to infect humans. The image shows soil amoeba (labeled in green) and their chlamydial symbionts (labeled in orange).

Chlamydiae expand our view on how intracellular bacteria evolve

Despite being intracellular symbionts, some chlamydiae could gain important genes through gene transfer from other bacteria.

Illustration of an Asgard archaeon. Under water, a roundish structure with several worm-like appendages. In some places the cell membrane (blue) is not drawn, so that the inside becomes visible: granular material connected with fine rods (orange). In the background, some bean-shaped structures (bacteria) and more Asgard archaea are blurred.

Fig. 1: Summary of atmospheric transport from the Tropical Pacific Ocean. Solid arrows show an increase in mass transport during El Niño; dashed arrows a decrease. Blue arrows show the transport of relatively moist air to anomalously moist local conditions (marked with blue shading), while brown arrows show transport of dry air to anomalously dry local conditions (brown shading). Red circles show transport of warm air aloft that favors stable conditions. Orange shading shows transport of anomalously greater amount of heat from the Pacific Ocean to the Tropical Atlantic.
