Flagellar filament formation is increased in a STM1267 deletion mutant.

<p>Top: Histogram of counted flagella per cell body of the wildtype, a STM1267::FRT and STM3363::FRT deletion mutant. The average filament numbers per cell based on a Gaussian non-linear regression analysis is indicated in the figure. Bottom: Flagellar filament formation was analyzed by flagellin immunostaining using α-FliC primary and α-rabbit conjugated Alexa Fluor 488 secondary antibodies (green) in a strain background locked for <i>fliC</i> expression. The membrane was stained with FM-64 (red) and DNA with DAPI (blue). Scale bar = 2 μm.
