Fig. 5. The expression of histone H1.X::GFP in head neurons and marginal cells (A)
as well as in an excretory channel cell (C). H1.X::GFP is a cytoplasmic
protein in both cell types. The neuronal projections are visualized by
H1.X::GFP fluorescence. (B,D) are the corresponding Nomarski micrographs.
