pathΔ/pathΔ mutants do not show significant defects in larval growth. pathΔ/pathΔ or pathΔ/Df(3L)BSC773 larvae show defects in C4da dendrite growth, with pathΔ/Df(3L)BSC773 mutants showing significant reductions in dendrite length compared to wild type. pathGFP/pathdg50 or pathGFP/pathΔ larvae show normal dendrite growth in C4da neurons.
