Consistent with the previously described microinjections of the non-GFP constructs, only the full-length
ssu-1::GFP fusion rescued the suppression of the locomotion defect of
unc-1(null) by
ssu-1(
fc73). However, both constructs produced strong fluorescence in only two head neurons. Using the amphid stain DiI, these two head neurons were identified as the ASJ amphid neurons.
