The
sol-2 promoter drives expression of GFP in many head and tail neurons, including neurons that express the GLR-1 subunit, as well as the SOL-1 auxiliary subunit (Brockie et al., 2001a; Zheng et al., 2004). SOL-2 is also expressed in neurons that do not express either GLR-1 or SOL-1. SOL-2 is expressed in the command interneurons, as shown by coexpression of mCherry driven by the
nmr-1 promoter.
