Neurexin/nrx-1 expression in all neurons, but not in DVB alone, rescues starvation-induced DVB neurites in nrx-1 mutants. (A) Confocal z-stack maximum projections of DVB neuron in fed and mid-L4 starved nrx-1(wy778) males with control, DVB::nrx-1 (lim-6int4::birA::nrx-1), or neurons::nrx-1 (ric-19prom6::birA::nrx-1) transgenes at day 1 of adulthood. Bar, 10 μm) Quantification of (B) total neurite length and (C) neurite junctions for DVB in fed control and fed and mid-L4 starved nrx-1(wy778) males with control, DVB::nrx-1 (lim-6int4::birA::nrx-1), or neurons::nrx-1 (ric-19prom6::birA::nrx-1) transgenes at day 1 of adulthood.
