FIGURE 5.2

A primordial nose. Immunoelectron microscopy shows that the chemoreceptor complex of E. coli bacteria is clustered at a discrete polar location of the cell’s inner membrane (arrow) (Maddock and Shapiro 1993). This cellular sequestration of chemoreceptive machinery represents an ancient forerunner of regional sensory specialization. (From Maddock, J.R., Shapiro, L. Science, 259, 1720, 1993.
