Abstract

Electron-microscopic analysis of cytomictic channels formation in the pollen mother cells in tobacco at the stage of meiosis prophase I of anthers has been conducted. The cytomictic channels in the pollen mother cells in tobacco have been established to be formed under the basis of both single plasmodesmata and de novo with the involvement of specific electron-dense bodies. The role of cytomictic channels in microsporogenesis regulation is discussed.
