Cytomixis in plants: facts and doubts
Protoplasma, 2017The migration of nuclei between plant cells (cytomixis) is a mysterious cellular phenomenon frequently observable in the male meiosis of higher plants. Cytomixis attracts attention because of unknown cellular mechanisms underlying migration of nuclei and its potential evolutionary significance, since the genetic material is transferred between the ...

Cytological Techniques to Study Cytomixis in Plant Male Meiosis.
Methods in molecular biology, 2020In this chapter we describe cytological techniques to study cytomixis, a process of nuclear migration between plant cells, in squashed plant male meiocytes of Nicotiana tabacum and Secale cereale. To perform immunostaining or fluorescence in situ hybridization (FISH) on meiotic cells involved in cytomixis common protocols are modified.

Nucleoli migration coupled with cytomixis
Biologia, 2016Nucleolus was regarded as a mere ribosome-producing factory for many decades however, in the past two decades; this has come to the light that it is a plurifunctional nuclear domain which plays vital role in many cellular processes. Despite many advances, much remains to be revealed about the nucleolus association with cellular processes.

Cytoskeleton and nucleoskeleton involvement in processes of cytomixis in plants
Cell Biology International, 2019AbstractCytomixis is a form of cell‐to‐cell nuclear migration that involves the interaction of dynamic cytoskeletal components with the nucleus through signalling systems and linker complexes. In cytomixis two known mechanisms can be involved: actomyosin and/or microtubules and their associated motors.

Cytomixis in the cereal (Gramineae) microsporogenesis
Protoplasma, 2015The specific features in behavior of the nuclei and chromatin migrating through cytomictic channels as well as in formation of micronuclei in the cereal microsporogenesis have been studied. Immunofluorescence microscopy has allowed for demonstration that the tubulin cytoskeleton does not play a significant role in the intercellular migration of nuclei.

Migration of DNA-Containing Organelles between Tobacco Microsporocytes during Cytomixis
Russian Journal of Developmental Biology, 2018Ultrastructural 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.

How cytomixis can form unreduced gametes in tobacco
Plant Systematics and Evolution, 2015Cytomixis is migration of the nuclei between cells, widespread in various higher plant species. Most frequently, cytomixis takes place in microsporogenesis and is assumed to be a possible cause of unreduced gamete generation. In the present work the cytological mechanisms leading to a change in the cell chromosome number via cytomixis in tobacco ...

Analysis of cytomixis in tobacco microsporocytes with confocal laser scanning microscopy
Protoplasma, 2016Confocal laser scanning microscopy for the first time is used to examine the structure of the tobacco microsporocytes involved in the intercellular migration of nuclei (cytomixis). As is observed, the cytomictic channels are distributed over the surface of tobacco microsporocytes in a non-random manner and their number depends on the meiotic stage ...

High frequency of cytomixis observed at zygotene in tetraploid Lippia alba
Plant Systematics and Evolution, 2015Lippia alba (Verbenaceae) is an aromatic shrub recently described as a new tropical polyploid species with five distinct chromosome numbers (2n = 30, 38, 45, 60, and 90) with 2n = 30, 45, and 60 being the most frequent ones. Cytomixis is a cellular process known as the migration of genetic material mainly between meiocytes through cytoplasmic ...
