Resumo
Ultrastructural analysis of intercellular migration of DNA-containing organelles (nuclei, mitochondria, and plastids) in tobacco microsporogenesis during cytomixis was conducted. It was demonstrated for the first time that the migrating part of the nucleus is covered with ribosomes and can contain the accumulation of nuclear pores. The possibility of mitochondrial migration between the plant cells was proven for the first time. It was demonstrated that mitochondria extremely rarely pass into neighboring cells, and their movement occurs through one cytomictic channel. In turn, plastids can generate the accumulations around cytomictic channels and actively migrate between the cells, even through small size cytomictic channels. It was established that plastids can pass into another cell through one or several cytomictic channels, and several plastids can also simultaneously migrate through one channel. The consequences of migration of DNA-containing organelles in the cells producing the pollen are discussed.
