Summary
Using electron microscopy, more details have been found in the fine structure of dolipores in some basidiomycetes: 1. The pore channel may be closed by 1–3 membranes or plugs. 2. The parenthesome is covered by large plugs of material rich in ribosomes which is separated from the cytoplasm by endoplasmic reticulum. It is suggested that this “outer cap” controls the intercellular transport.
Zusammenfassung
Bei den Doliporen einiger Basidiomyceten sind weitere Differenzierungen bekannt geworden. 1. Der Porenkanal kann durch 1–3 Membranen oder durch Pfropfen verschlossen werden. 2. Das Parenthesom ist von einem ribosomenreichen Material bedeckt, das durch endoplasmatisches Reticulum vom übrigen Cytoplasma abgegrenzt wird. Diese “Abßenkappe” kontrolliert vielleicht den Stofftransport.
