C. elegans fmi-1/flamingo and Wnt pathway components interact genetically to control the anteroposterior neurite growth of the VD GABAergic neurons

► VD neurons have axons that are misdirected posteriorly in fmi-1 mutants. ► fmi-1 functions independent of the core PCP pathway genes, prkl-1 and vang-1. ► The Wnt signaling genes, dsh-1 and lin-17, work in a parallel pathway. ► Defects occur in the early axon extension from the cell body.
