METPO:1005037 · CLASS · SEEDED

A motility phenotype in which flagella are located near but not at the cell pole.

Trait evidence (2)

DOI:10.1128/JB.01405-06
The cell has two sets of flagellar systems, one thick flagellum and a few thin flagella, uniquely growing at subpolar positions.

Kanbe et al. describe two morphologically distinct Bradyrhizobium flagellar systems that both emerge from subpolar positions.
DOI:10.3390/biom10050774
Under the growth conditions commonly used in the laboratory, a single subpolar flagellum that traverses the cell membrane, is assembled on the surface.

Camarena and Dreyfus review the Rhodobacter sphaeroides Fla1 system as a second bacterial example of subpolar flagellation.
