Figure 7. Model for direct and indirect Ppa-EGL-4 regulation of pharyngeal pumping rate on E. coli OP50.

Figure 7

The loss of Ppa-EGL-4 increases pumping rate directly by regulating pharyngeal neurons, as well as indirectly by increasing the number of animals with the narrower stenostomatous mouth form in the population.
