Figure 7. Embryonic expression and subnuclear localization of H1.X. (A,B) show H1.X::GFP fluorescence detection in a few cells in the periphery of a > 100-cell stage embryos. In (A), a fixed specimen shows a shallow fluorescence of the nucleoplasm and bright fluorescence of the nucleoli, whereas in (B), a live observation shows a shallow fluorescence in the cytoplasm and a bright fluorescence of the nucleoplasm. The brightest spots in the nucleoplasm correspond to the nucleoli. Bars, 20 um.
(A and A') GFP-SFT-4 localizes to reticularnetwork structures in the middle of intestinal cells (A) andpunctate structures beneath the cell surface (A'; arrows).GFP-SFT-4 expression was driven by sft-4 promoter.
