zzEx10 [(pJE3) eff-1p::GFP + rol-6(su1006)]. Pick Rollers to maintain. eff-1p expression is observed in epithelia committed to fusion and in fused syncytia.

zzIs16 [(pJE3) eff-1p::GFP + rol-6(su1006)]. GFP+ Rollers. Chromosomal insertion of zzEx10. Integration site of zzIs16 not yet mapped, but it is not tightly linked to eff-1 II, unc-119 III, or jcIs1 IV. pJE3 has 7.5 kb of eff-1 upstream sequence inserted into pPD95.75, driving cytoplasmic GFP expression.
