Expression of a des-2 lacZ fusion. This pattern is similar to that for deg-3 expression (7). Identified cells include the M1 head muscles (the staining in front of the IL2 neurons; these cells were identified by their structure in a des-2 gfp expressing strain), IL2 neurons (these cells disappear in unc-86 animals), FLP neurons (these cells disappear in mec-3 animals), PVD neurons (identified by the pattern of their processes using a des-2 gfp fusion and because they disappear in mec-3 and unc-86 animals), and PVC neurons (these cells disappear in deg-1 animals).
