The Hyphal Tip Cell of Sclerotium Rolfsii: Cytological Observations

  • R. W. Roberson
Part of the NATO ASI Series book series (ASIH, volume 53)


The hyphal apex is a highly specialized region of the fungal cell where polarized growth and differentiation occur. Numerous cellular activities are involved in maintaining apical growth and morphogenesis in fungi. Among these are the apical migration of cytoplasmic vesicles transporting materials used for plasma membrane and wall formation, the incorporation of these vesicles into the Spitzenkorper in higher fungi, the positioning and movement of the Spitzenkorper in the apex, and the final delivery of vesicles from the Spitzenkorper to the apical plasma membrane. How the cell regulates and coordinates these events during hyphal growth and development is not totally clear, although it is assumed that the cytoskeleton is primarily involved (Bartnicki- Garcia et al., 1989; Howard and Aist, 1980; McKerracher and Heath, 1987; Tucker et al., 1986; Wessels, 1986).
