polar flagellation

METPO:1005032 · CLASS · SEEDED

A motility phenotype in which one or more flagella are located at one or both poles of the cell.

DOI:10.1093/femsre/fuv034
Bacteria differ in number and location of their flagella that appear in regular patterns at the cell surface (flagellation pattern).

Schuhmacher et al. support treating the number and cellular position of flagella as a flagellation-pattern morphology class.
DOI:10.3390/biom10040533
Some bacterial species, such as the marine bacterium Vibrio alginolyticus, have a single polar flagellum that allows it to swim in liquid environments.

Kojima et al. give Vibrio alginolyticus as a direct bacterial example whose flagellum is positioned at a cell pole.
DOI:10.3390/biom10040533
Two regulators, FlhF and FlhG, function antagonistically to generate only one flagellum at the cell pole.

Kojima et al. connect FlhF/FlhG regulation to generation of a polar flagellum, supporting polar placement as a microbial flagellation phenotype.
