An
egl-46 transcriptional reporter confirmed the previously published expression pattern for
egl-46 in the FLP, HSN and PVD neurons and other neurons in the head. In addition, the
egl-46 reporter colocalized with
egl-13::gfp reporter (expressed in BAG, URX, AQR and PQR) in the BAG neurons at the L2 and L3 stages of larval development; suggesting that
egl-46 is expressed during short temporal window in the BAG neurons, as has been observed in other neurons previously (WU et al. 2001). Note: we only rarely observed colocalization with the BAG marker, suggesting that the
egl-46 promoter drives expression in the BAG neurons in a transient manner.
