Plasma membrane-cell wall connections: Roles in mitosis and cytokinesis revealed by plasmolysis of Tradescantia virginiana leaf epidermal cells
Tradescantia virginiana leaf epidermal cells were plasmolysed by sequential treatment with 0.8 M and 0.3 M sucrose. Plasmolysis revealed adhesion of the plasma membrane to the cell wall at sites coinciding with cytoskeletal arrays involved in the polarisation of cells undergoing asymmetric divisions - cortical actin patch - and in the establishment and maintenance of the division site - preprophase band of microtubules and filamentous (F) actin. The majority of cells retained adhesions at the...[Show more]
