dc.description.abstract | Mitochondria change their morphology and distribution depending on the metabolism and functional state of a cell. Here, we
analyzed the mitochondria and selected structures in female germ-line cysts in a representative of clitellate annelids – the white
worm Enchytraeus albidus in which each germ cell has one cytoplasmic bridge that connects it to a common cytoplasmic mass.
Using serial block-face scanning electron microscopy (SBEM), we prepared three-dimensional ultrastructural reconstructions of the
entire selected compartments of a cyst at the advanced stage of oogenesis, i.e. the nurse cell, cytophore, and cytoplasmic bridges of all
16 cells (15 nurse cells and oocyte). We revealed extensive mitochondrial networks in the nurse cells, cytophore and mitochondria
that pass through the cytoplasmic bridges, which indicates that a mitochondrial network can extend throughout the entire cyst.
e dynamic hyperfusion state was suggested for such mitochondrial aggregations. We measured the mitochondria distribution
and revealed their polarized distribution in the nurse cells and more abundant accumulation within the cytophore compared to the
nurse cell. A close association of mitochondrial networks with dispersed nuage material, which seems to be the structural equivalent
of a Balbiani body, not described in clitellate annelids so far, was also revealed. | pl_PL |
