Describes the changes in the structure and distribution of plasmodesmata during the development of C. vulgaris anterydiostanów and C. tomentosa since the creation of the 24-cell germ to form mature spermatozoidów. These changes are associated with well-defined stages of differentiation, and may provide for adjustment of the structure and function of plasmodesmata in intercellular communication to the changing situation morphogenetic. It has been suggested that regulatory mechanisms symplastycznej the development and operation of the plant are universal.
