The cytomictic channels in pollen mother cells of tobacco can be formed by two distinct ways: on the basis of plasmodesmata and de novo without any relation to ones. Cytomictic channels formation it was shown to be possible on the basis of single plasmodesma. It is not unlikely that special electron-dense bodies involve de novo formation of the channels. Also the role of cytomictic channels in the pollen development regulation is discussed.

Key words: cytomixis, pollen mother cells, cytomictic channels, plasmodesmata
