Intron 7-driven GFP reporter fluorescence was first detected in two head neurons in post-gastrulating embryos; based on reporter gene expression, one of those neurons is likely to be AVG. The identification of this neuron as AVG in larval stages was confirmed by co-localization with two reporters,
glr-1::DsRed and
odr-2::DsRed (Chou et al., 2001; Maricq et al., 1995). The other unidentified cell had variable fluorescence. Fluorescence in
lin-11-
int-7p::GFP animals persisted in both neurons throughout the larval stages, but the intensity decreased with time. Adults showed faint expression mostly in AVG.
