wdIs3[del-1::GFP + dpy-20(+)]. del-1 is expressed in the VB motor neurons beginning the the L2 larval stage. By the end of L2, del-1::GFP is also visible in a few VA motor neurons at the anterior end of the nerve cord. Expression of del-1::GFP in the VAs progresses in a wave from anterior to posterior, with all VAs expressing del-1::GFP by the adult stage. Thus, del-1::GFP is not expressed in the VAs during the L2 period in which unc-4 functions in those cells to establish synaptic inputs but is expressed in the VAs after they have been wired into the ventral cord circuit. del-1::GFP is also expressed in five neurons (VB1, VB2, SABVR, SABVL, VA1) in the retrovesicular ganglion at the anterior end of the ventral nerve cord. During the mid-L2 larval stage, del-1::GFP expression in the ventral nerve cord is largely restricted to the VB class of motor neurons.
