All living cells sense and respond to changes in external or internal conditions. Without that
cognitive capacity, they could not obtain nutrition essential for growth, survive inevitable …

Echoing the repeated convergent evolution of flight and vision in large eukaryotes,
propulsive swimming motility has evolved independently in microbes in each of the three …

Archaea play indispensable roles in global biogeochemical cycles, yet many crucial cellular
processes, including cell-shape determination, are poorly understood. Haloferax volcanii, a …

Bactofilins are rigid, nonpolar bacterial cytoskeletal filaments that link cellular processes to
specific curvatures of the cytoplasmic membrane. Although homologs of bactofilins have …

Some microbes display pleomorphism, showing variable cell shapes in a single culture,
whereas others differentiate to adapt to changed environmental conditions. The pleomorphic …

Compared with the extensive knowledge on cell division in model eukaryotes and bacteria,
little is known about how archaea divide. Interestingly, both endosomal sorting complex …

Live-cell imaging has revolutionized our understanding of dynamic cellular processes in
bacteria and eukaryotes. Although similar techniques have been applied to the study of …

In most bacteria, cell division depends on the tubulin homolog FtsZ and other proteins, such
as SepF, that form a complex termed the divisome. Cell division also depends on FtsZ in …

Tubulin superfamily (TSF) proteins are widespread, and are known for their multifaceted
roles as cytoskeletal proteins underpinning many basic cellular functions, including …

CetZ proteins are archaea-specific homologs of the cytoskeletal proteins FtsZ and tubulin. In
the pleomorphic archaeon Haloferax volcanii, CetZ1 contributes to the development of rod …
