Figure 3

Pharyngeal neuron defects in ten-1 mutants. Each series shows the following: a cartoon representation of the normal morphology of the examined neuron, photographs of the wild-type neurons visualized with a specific GFP reporter (N2; see materials and methods), and mutant animals (ok641) with typical defects indicated by arrowheads. (C) Shows a different focal plane of the worm shown in (B) to make the ends of the distal M2s visible. The arrowheads indicate a misplaced M2 neuron cell body (D), conspicuous varicosities (G, K, O), ectopic branches (H), misguided axons (L) or truncated axons (R). The scale bar in (B) represents 20 μm and applies to all photographs.
