Occurrence of microtubules in the hyphae of Schizophyllum commune during intercellular nuclear migration

Summary

During the intercellular nuclear migration of the basidiomycete Schizophyllum commune cytoplasmic microtubules were frequently observed scattered in the hyphae around interphase nuclei and connected with a semiglobular structure at the poles of mitotic and postmitotic nuclei. Thus it seems possible that microtubules, which have been demonstrated to participate in the intracellular nuclear movements in the dikaryotic hyphae of the basidiomycetes, are also involved in the intercellular nuclear movements of these fungi. During hyphal fusion microtubules close to an interphase nucleus were connected with electron-dense structures. It is suggested that these structures are centers for the assembly of microtubules necessary for nuclear movements not associated with nuclear divisions.
