Based on our observations, compared with wheat, barley, and maize with relatively larger chromosomes, sunflower possesses smaller chromosomes and high-density cytoplasm.
But in sunflower, identification of individual chromosomes on a meiotic spread can be a problem because of the large number of chromosomes and high-density cytoplasm.
Z-series analysis (not shown) indicates that the nuclei of the PCP expressing cells within these zones reside near the basal region of this epithelium, to the hemolymph side of the high density nuclei, with PCP-positive cytoplasm extending through the epithelium from hemolymph side to cuticle side.
However, the effective persistence lengths of MTs in oocytes is likely shorter due to effects of cytoplasmic flows as well as high density of yolk granules and other obstacles in the cytoplasm that induce MT bending.
Cells with dense cytoplasm show a very high density of free ribosomes and contain many rough endoplasmic reticulum and mitochondria (Figure 4B).
Morphologically, Dysbindin is localized mainly in the cytoplasm with a perinuclear high density region in HEK293 cells and SY5Y cells; however, a faint immunoreaction was also seen within the nucleus (Figure 1B -a and -b).
Phosphorylation of serine residues is likely to play an important role in copper ATPase's regulation and trafficking (23), and in our experiments, the high level of serine phosphorylation may account for the high density of ATP7B associated with trafficking vesicles in the cytoplasm of cells subjected to a copper load.
This higher density in the cytoplasm was detectable even under phase contrast microscopy, which showed the cell cytoplasm carrying the nanoparticles with a granular structural pattern, while in the surrounding cells there were no signs of these structures (Figs. 4A, B).
At H22 p.i., the immature small forms reach high density and mature bacteria (both crescent and round forms) accumulate, filling the cell cytoplasm.
These nanoparticle-carrying cells not only appeared as individual cells in the parenquima, but "chains" of several adjacent parenchymatic cells (2 to 5) were also frequently observed carrying nanoparticle aggregates and with the same higher density in the cytoplasm (Figs. 5A, B).
