a
Complementation assays were performed as described in the legend to Fig. 3.
b
Phenotypes are designated as aerotactic (+), partially aerotactic (+/−) and non-aerotactic (−) as described in the text.
c
The diameter of partially aerotactic swarms was approximately 50% the diameter of aerotactic swarms. The rings of partially aerotactic swarms were also less well defined.
