Correlation analysis in an artificial filamentous cell. (A) The phase-contrast image of an artificial filamentous cell and beads (top) and the fluorescence image of this cell (bottom). Motors 1, 2, 3, and 4 represent bead-labeled flagellar motors whose rotation could be analyzed. In this filamentous cell, many fluorescent spots (>10) derived from GFP-CheW were randomly distributed along the length of the cell. This observation indicated that there were many lateral chemoreceptor patches in the cell. Bar, 1.0 μm. (B) Correlation analyses for the switching between each pair of flagellar motors. Red arrow indicates near-0-s peak of correlation. The distances between motors 1 and 2, 1 and 3, 1 and 4, 2 and 3, 2 and 4, and 3 and 4 were 2.2, 6.2, 6.8, 4.1, 4.7, and 0.7 μm, respectively.
