The nitrogen-fixing symbiosis requires CbrA-dependent regulation of a DivL and CckA phosphorelay.

The cell cycle is a fundamental process involved in bacterial reproduction and cellular differentiation. For , cell cycle outcomes depend on its growth environment. This bacterium shows a tight coupling of DNA replication initiation with cell division during free-living growth.

Publisher Correction: Host-associated microbiomes are predicted by immune system complexity and climate.

Following publication of the original paper [1], it was reported that an error in the processing of Fig. 8 occurred. In the online HTML version of the article, Fig.

Host-associated microbiomes are predicted by immune system complexity and climate.

Background: Host-associated microbiomes, the microorganisms occurring inside and on host surfaces, influence evolutionary, immunological, and ecological processes. Interactions between host and microbiome affect metabolism and contribute to host adaptation to changing environments. Meta-analyses of host-associated bacterial communities have the potential to elucidate global-scale patterns of microbial community structure and function.
