Gliding cells of Myxococcus xanthus producing a BacM-mCherry fusion protein, which forms a fluorescent screw-like structure near one of the cell poles. (A) Cell of A+S+ strain EH362, which expresses bacM-mCherry; 48 h after spotting on TPM agar. (B) Cell of A+S− strain EH367, which expresses bacM-mCherry in the absence of bacM and pilQ; 60 h after spotting on TPM agar. Gliding was observed under phase contrast while BacM-mCherry fluorescence was recorded concomitantly. White bars represent 2 μm; reversals of gliding direction are marked by “Rev”. Note, that during gliding none of the screw structures changes its relative orientation within any of the cells (see corresponding Movies 2A and 2B).
