xnIs23 [cdc-42p::ZF1::GFP::cdc-42 + unc-119(+)]. xnEx342 [rab-3p::zif-1 + rab-3p::mCherry + rol-6(su1006)]. Pick Rollers to maintain. ZF1::GFP::cdc-42 is expressed ubiquitously and enriched at the plasma membrane. In embryos inheriting xnEx342, ZF1::GFP::cdc-42 is degraded and mCherry is expressed in neurons.
