Extremely faint nuclear localized GFP in embryos, from an early stage. Pattern appears to be the same as described for other
pes-1 fusions (see Hope, I.A., ('94) Development, 120, 505-14) . Two more strains that were lost showed what looked to be the same expression pattern, with the signal intensity being higher in one of those strains than in the remaining 3 but the fluorescence intensity was still very weak. In the strain expressing more strongly, expression could be seen up to L1 when it was expressed in Z1 and Z4.
