Nuclei in unc-84(Δ556–861) embryos and larva do not display narrower NE spacing than wild type. (A–C) TEM performed on unc-84(n369) transgenic nuclei expressing unc-84(Δ556–861) revealed that NE spacing in embryos (A) and muscle nuclei (B and C) were indistinguishable from wild type. Bars, 500 nm. (D) Quantitation of the maximum nuclear membrane distance confirmed that PNS widths in unc-84(Δ556–861) muscle cells were not significantly different than wild type (P = 0.2785). The horizontal bars denote the mean values.
