What is “the basal body part”? Basal body is an organelle of eukaryotic cell. If this means the connection of junctional pore tube and inner membrane, it is clearly seen in the figure, as well as in old paper by Halfen and Castenholz. A high quality figure is provided as Supplementary Figure S1. The “bulges” in the inner membrane are also visible. In the Line 183, the description was revised.
Overall, this study presents observations related to slime-mediated motility on multiple scales (molecular, single-filament and colony), and integrates these findings into a coherent model for the relationship between the cellular organization and the behavior of the colony.
