Bacterial Locomotion and Signal Transduction

This review of BLAST IV began with considerations of nonenteric bacteria that behave in strange (to the enterocentric mind) and wonderful ways. To close the circle, it is fitting that it should also end with an organism, like B. subtilis, that does things differently. These examples highlight the fact that we have just begun to unravel the marveously diverse solutions to environmental sensing and adaptive response that have evolved during nearly four billion years of prokaryotic life on earth.
