a
Representative data from three assays of swim zone area and percent reduction in the absence and presence of ethanol (EtOH) for T4P alignment complex mutants and minor pilin mutants.
b
Negative percentages indicate strains where motility in ethanol was greater than that of the no ethanol control.
c
P values of statistical analysis comparing control and ethanol samples using two-way ANOVA.
