Phylogenetic analyses of conserved core genes have disentangled most of the ancient relationships in Archaea. However, some groups remain debated, like the DPANN, a deep-branching super-phylum composed of nanosized archaea with reduced genomes. Among these, the Nanohaloarchaea require high-salt concentrations for growth.

In addition of acting as obstacles to light radiations and chemical reactors, they are possible atmospheric oases for airborne microorganisms, providing water, nutrients and paths to the ground. Microbial activity was previously detected in clouds, but the microbial community that is active in situ remains unknown.

- - Despite their ecological importance, microbial eukaryotes in freshwater systems receive less research focus than prokaryotes, which can lead to biases in understanding their role in biogeochemical cycles.
- - The study identified around 100,798 operational taxonomic units (OTUs) of microbial eukaryotes, suggesting a total diversity of 200,000-250,000 species, with notable groups like Amoebozoa and Viridiplantae needing further study.
- - Network analysis highlights that Fungi, Stramenopiles, and Viridiplantae are crucial to lake ecosystems, and the research emphasizes the need for better metabarcoding data to enhance knowledge of microbial eukaryotic diversity.
Background: Two-component systems (TCS) play critical roles in sensing and responding to environmental cues. Azospirillum is a plant growth-promoting rhizobacterium living in the rhizosphere of many important crops. Despite numerous studies about its plant beneficial properties, little is known about how the bacterium senses and responds to its rhizospheric environment.
