Motility of the flagellar mutants in liquid and semisolid agar compared to cells carrying the wild-type allele
| Allele | Swimming behavior in liquid medium | Relative chemotaxis ring size on: |
|
|---|---|---|---|
| 0.35% agar | 0.30% agar | ||
| Wild type | Alternative run and tumble | 1 | 1 |
| M1 | Cell bodies wobble more | 0.5 | 0.5 |
| M2 | Only tumble, never swim in a straight line | 0 | 0 |
| M3 | Nonmotile | 0 | 0 |
| M12 | Tumble, cells may swim in a line of <2 μm | 0 | 0.1 |
| M13 | Nonmotile | 0 | 0 |
| M23 | Almost indistinguishable from the wild type | 0.9 | 0.9 |
| M123 | Cell bodies wobbled more and with longer runs | 0 | 0.4 |
