How new functions evolve fascinates many evolutionary biologists. Particularly captivating is
the evolution of rotation in molecular machines, as it evokes familiar machines that we have …

Archaea swim using the archaellum (archaeal flagellum), a reversible rotary motor
consisting of a torque-generating motor and a helical filament, which acts as a propeller …

In recent years, novel imaging approaches revolutionised our understanding of the cellular
and molecular biology of microorganisms. These include advances in fluorescent probes …

Diverse archaea, including many unknown species and phylogenetically deeply rooted taxa,
survive in extreme environments. They play crucial roles in the global carbon cycle and …

How complex, multi-component macromolecular machines evolved remains poorly
understood. Here we reveal the evolutionary origins of the chemosensory machinery that …

Histidine kinases are key components of regulatory systems that enable bacteria to respond
to environmental changes. Two major classes of histidine kinases are recognized on the …

Archaella are the swimming organelles in the Archaea. Recently, the first archaellum
regulator in the Euryarchaeota, EarA Mma, was identified in Methanococcus maripaludis …

The FrzCD chemoreceptor from the gliding bacterium Myxococcus xanthus forms
cytoplasmic clusters that occupy a large central region of the cell body also occupied by the …

Chemotaxis in Pseudomonas species is one of the most diversified and best-understood
signal transduction network. Most strains possess one or two sets of the chemotaxis genes …

The chemotactic sensory system enables motile bacteria to move toward favorable
environments. Throughout bacterial diversity, the chemoreceptors that mediate chemotaxis …
