Changes in ultrastructure of plasmodesmata during spermatogenesis in Chara vulgaris L
1Department of Plant Cytology and Cytochemistry, Institute of Physiology and Cytology, University of Łódź, ul. Banacha 12/16, PL-90-237, Łódź, Poland.
Abstract:
Two types of plasmodesmata are found within an antheridium of Chara vulgaris: open plasmodesmata filled with electron-transparent cytoplasm, and plugged plasmodesmata, filled with an osmiophilic dense substance. Open plasmodesmata occur only between cells synchronized completely in respect of their advancement in cell-cycle progression or differentiation. Plugged plasmodesmata connect different types of cells or cells of the same type at various stages of the cell cycle. Open plasmodesmata may become plugged, and vice versa. These changes are connected with the limitation or extension of synchronization of cellular divisions and differentiation within the groups of cells in the antheridium.
