irx-1 RNAi suppresses the dorsal (dorsal nerve cord) gain and ventral (ventral nerve cord) loss of SNB-1::GFP puncta (marking GABAergic neuro-muscular junctions) caused by the unc-55(e1170) mutation
ur280 suppresses dorsal guidance defects caused by the unc-6(rh46) mutation. ur280 and other suppressors, improve the ability of DA and DB motor axons to reach the dorsal cord in the unc-6(rh46) background.
