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.

Cytomixis with actual transfer of chromatin material has been recorded in 6 woody species, from early prophase to telophase-II. It is more common at early stages of meiosis. Number of pollen mother cells involved vary from 2–8. As a consequence of chromatin migration both hypo and hyperploid meiocytes are seen inSerissa foetida, Symplocos chinensis ...

Cytoskeleton and nucleoskeleton involvement in processes of cytomixis in plants
Cell Biology International, 2017AbstractCytomixis 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.

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 ...

A rise of ploidy level influences the rate of cytomixis in tobacco male meiosis
Protoplasma, 2015The effect of plant ploidy level on the rate of cytomixis in microsporogenesis has been analyzed with the help of a unique model, the collection of tobacco plants of different ploidies (2n = 2x = 24, 4x = 48, 6x = 72, and 8x = 96). As has been shown, the rate of cytomixis proportionally increases in 6x and 8x cytotypes, being rather similar in 2x and ...

Chromosoma, 1976
Cytomixis is a spontaneous process occurring through the formation of cytoplasmic bridges between adjacent pollen mother cells. This phenomenon was observed in the pollen mother cells of 3 genotypes of Lolium perenne which had been subjected to directional selection for productivity of green material.

Cytomixis in Agropyron cristatum
Genome, 1987An Agropyron cristatum plant (CB-9-41), crested wheat grass, and its vegetative clones have been identified that contain pollen mother cells that have a gain or a loss in chromatin (DNA). CB-9-41 was identified during the course of an experiment to determine the effectiveness of colchicine on the doubling of the chromosome complement.

Distribution of telomeres in the tobacco meiotic nuclei during cytomixis
Cell Biology International, 2015AbstractCytomixis is the migration of nuclei from one cell to another in higher plants, most frequently observable during microsporogenesis, which has a potential evolutionary significance. Currently, a major challenge is to label the chromatin migrating between cells to clarify its further fate.

An ultrastructural study of cytomixis in tobacco pollen mother cells
Protoplasma, 2011Intercellular chromatin migration (cytomixis) in the pollen mother cells of two tobacco (Nicotiana tabacum L.) lines was analyzed by electron microscopy during the first meiotic prophase. The maximal manifestation of cytomixis was observed in the pachytene.

Cytological Techniques to Study Cytomixis in Plant Male Meiosis
2019In 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.
